Any outdoor antenna must be located away from all power lines.

OUTDOOR ANTENNA GROUNDING

If an outside antenna is connected to your tuner or tuner-

preamplifier, be sure the antenna system is grounded so as to

provide some protection against voltage surges and built-up static

charges. Article 810 of the National Electrical Code, ANSI/NFPA No.

70-1984, provides information with respect to proper grounding of

the mast and supporting structure, grounding of the lead-in wire to

an antenna discharge unit, size of grounding conductors, location of

antenna discharge unit, connection to grounding electrodes and

requirements for the grounding electrode.

a. Use No. 10 AWG (5.3mm2) copper, No. 8 AWG (8.4mm2)

aluminium, No. 17 AWG (1.0mm2) copper-clad steel or bronze

wire, or larger, as a ground wire.

b. Secure antenna lead-in and ground wires to house with stand-off

insulators spaced from 4-6 feet (1.22 - 1.83 m) apart.

c. Mount antenna discharge unit as close as possible to where lead-

in enters house.

d. Use jumper wire not smaller than No.6 AWG (13.3mm2) copper,

or the equivalent, when a separate antenna-grounding electrode

is used. see NEC Section 810-21 (j).

IMPORTANT SAFETY INSTRUCTIONS

1. REAR PANEL CONNECTIONS

3. FRONT PANEL CONTROLS

2. ANTENNA CONNECTION

4. REMOTE CONTROL HANDSET

10. NAD-LINK IN, OUT

The NAD-Link connector is used to pass commands from other

units fitted with NAD-Link connectors. This allows centralised

control of a complete system, and also allows some of the basic

functions of other NAD components (such as a CD player or

cassette-deck) also equipped with NAD-Link to be controlled with

the amplifier's remote control. To function with such other units,

connect the C730's NAD-Link Out to the NAD-Link In on the other

unit. NAD-Link connectors can be daisy-chained, IN to OUT, so

that a whole system can be controlled from the remote control

facilities of one unit.

NOTES:

It is advisable not to connect NAD-Link if these units that

have their own built-in remote control command receiver and are

positioned together, in direct view from the remote control

handset. If you are unsure, try operating the products without

NAD-Link first; If the unit responds to the remote control

command, it will not be necessary to connect NAD-Link.

Never loop the last unit back to the first NAD unit in the NAD-Link

chain. Unplug all units from the mains before connecting or

disconnecting NAD-Link.

11. SOFT CLIPPINGTM

When an amplifier is driven beyond its specified power output, a

hard, distorted sound can be heard on very loud sounds. This is

caused by the amplifier cutting off or "hard clipping" the peaks of

sound that it was not designed to reproduce. The NAD Soft

ClippingTM circuit gently limits the output of the system to

minimise audible distortion if the amplifier is overdriven.

If your listening involves moderate power levels you may leave the

Soft ClippingTM switch to Off. If you are likely to play at high levels,

that could stretch the amplifier's power capability, then switch Soft

Clip On.

12. 12V TRIGGER OUT

This output allows to remotely switch on or off ancillary

equipment such as a tuner, power amplifier, etc. which are also

equipped with a 12V trigger input. This can also be an AC outlet

power strip equipped with a 12V trigger input. The 12V trigger

output is activated whenever the unit is in switched to normal

operational mode from Stand-by or Off.

For switching Stand-by/Power On of an external component

through the C730, connect the12V-trigger output of the C730 to

the remote component's DC input jack. The plug required is a

standard 3.5mm Mini-Jack plug ("mono"): The tip is the live or

+ connection, the shaft of the input jack is the 12V-trigger - or

ground connection.

NOTES:

Check the specifications of the Trigger input terminal on the

other components to ensure these are compatible with the C730's

12V-trigger output. NAD components equipped with 12V input

triggers are fully compatible with the C730's 12V output trigger.

The C730's 12V-trigger output voltage is 12V DC. The total

maximum current must not exceed 200mA. Typically, NAD 12V

input triggers draw less than 10mA of current. Before making any

connections to any 12V trigger input or output, make sure all

components are disconnected from the AC mains.

Failure to observe the above may result in damage to the C730 or

any ancillary components attached to it. If in doubt over the

connections, installation and operation of the 12V trigger output

consult your NAD dealer.

13. SPEAKERS

Connect the right speaker to the terminals market "R +" and

"R-" ensuring that the "R+" is connected to the "+" terminal on

your loudspeaker and the "R-" is connected to the loudspeaker's

"-" terminal. Connect the terminals marked "L+" and "L-" to the

left speaker in the same way.

Always use heavy duty (16 gauge; 1.5mm, or thicker) stranded wire

to connect loudspeakers to your NAD C730. The high-current binding

post terminals can be used as a screw terminal for cables terminating

in spade or pin sockets or for cables with bare wire ends.

BARE WIRES AND PIN CONNECTORS

Bare wires and pin sockets should be inserted into the hole in the

shaft of the terminal. Unscrew the speaker terminal's plastic

bushing until the hole in the screw shaft is revealed. Insert the pin

or bare cable end into the hole and secure the cable by tightening

down the terminal's bushing.

Ensure bare wire from the speaker cables does not touch the back

panel or another socket . Ensure that there is only 1/2" (1cm) of

bare cable or pin and no loose strands of speakers wire.

NOTE:

Make sure the speaker impedance is 4 ohms or more

when connecting only one pair of speakers; make sure the

speaker impedance for all speakers is over 8 ohms when

connecting two sets of speakers.

14. AC LINE CORD

Plug the AC power cord into a live AC wall socket. Make sure all

connections have been made before connecting to mains.

15. SWITCHED AC OUTLET

The AC power cord of another component may be plugged into

this accessory outlet. Components plugged into this outlet will be

switched On and Off by the POWER button on the front panel or

by the ON and STAND-BY button on the remote control handset.

NOTE:

The total power consumption of any components

connected to the AC outlets may not exceed 100 Watts.

FRONT PANEL CONTROLS (FIG 3)

1. POWER ON/OFF

Press the POWER button to switch the receiver On. The Stand-by

indicator (No. 2) over the power button will light up amber and

after a short pause will turn to green to indicate the receiver is

now ready for normal operation.

Pressing the POWER switch again will turn the unit OFF

completely, it will not respond to the remote control.

QUICK START

1. Connect the speakers to the Speaker terminals and sources to

the relevant input sockets on the rear.

2. Plug in the AC power cord.

3. Press the POWER button to turn on the NAD C730.

4. Press the required input selector.

5. For radio listening, connect AM and FM antenna.

6. Press the AM/FM button to select AM or FM reception.

7. Press Preset/Tune button so that "PRESET" isn't lit in display;

the tuner is now in Tune mode.

8. Use Preset/Tune

to select a station.

NOTES ON INSTALLATION

Your NAD C730 should be placed on a firm, level surface. Avoid

placing the unit in direct sunlight or near sources of heat and

damp. Allow adequate ventilation. Do not place the unit on a soft

surface like a carpet. Do not place or it in an enclosed position

such a bookcase or cabinet that may impede the air-flow through

the ventilation slots. Make sure the unit is switched off before

making any connections.

The RCA sockets on your NAD C730 are colour coded for

convenience. Red and white are Right and Left audio respectively,

and yellow for NAD Link. Use high quality leads and sockets for

optimum performance and reliability. Ensure that leads and

sockets are not damaged in any way and all sockets are firmly

pushed home.

For best performance, use quality speaker leads of 16 gauge

(1.5mm) thickness or more. If the unit is not going to be used for

some time, disconnect the plug from the AC socket.

Should water get into your NAD C730, shut off the power to the

unit and remove the plug from the AC socket. Have the unit

inspected by a qualified service technician before attempting to

use it again. Do not remove the cover, there are no user-

serviceable parts inside. Use a dry soft cloth to clean the unit.

If necessary, lightly dampen the cloth with soapy water. Do not use

solutions containing benzol or other volatile agents.

REAR PANEL CONNECTIONS (FIG 1)

1. FM ANTENNA

A ribbon wire FM antenna is included and should be connected to

the FM connector at the rear of the unit using the supplied

"balun" adapter (see fig 2). The ribbon aerial should be mounted

on a vertical surface and placed so that it forms a "T".

Experiment with placement of the antenna to find the position that

gives the best signal strength and lowest background noise. An

inadequate FM signal normally results in high levels of hiss,

especially in stereo, and interference from external electrical

sources. In areas of poor FM reception, the tuner section's

performance can be improved by using an externally mounted FM

antenna. A qualified aerial installer will be able to advise and fit a

recommended aerial for your reception conditions.

2. AM ANTENNA

An AM loop antenna is supplied with the NAD C730 and is

required for AM reception. To connect the AM antenna, first press

the keys on the Antenna terminals downwards. Insert the bare

antenna wires into the two terminal holes and push the connector

keys upwards again to secure the connection (see fig 2).

Test various positions for the antenna but always ensure the loop

is placed vertically for best reception. Placing the antenna close to

large metal items such as metal shelves or radiators may interfere

with reception.

3. DISC INPUT

Input for additional line level input signals such as CD, Mini Disc

player or the output signal from a step-up amplifier for a

turntable. Use a twin RCA-to-RCA lead to connect the auxiliary

unit's left and right "Audio Outputs" to this input.

4. CD INPUT

Input for a CD or other line-level signal source. Use a twin RCA-

to-RCA lead to connect the CD player's left and right "Audio

Outputs" to this input. The NAD C730 only accepts analogue

signals from your CD player.

5. VIDEO INPUT

Input for the audio signal from a stereo VCR (or stereo

TV/Satellite/Cable receiver) or other line-level audio source.

Using twin RCA-to-RCA leads, connect to the left and right "Audio

Out" of the unit to these inputs. Note: These are audio inputs only.

6. AUX INPUT

Input for additional line level input signals such as another CD

player. Use a twin RCA-to-RCA lead to connect the auxiliary unit's

left and right "Audio Outputs" to this input.

7. TAPE 2 IN, OUT

Connections for analogue recording and playback to an audio

tape recorder of any type. Using twin RCA-to-RCA leads, connect

to the left and right "Audio Output" of the tape machine to the

TAPE 2 IN sockets for playback. Connect the left and right "Audio

Input" of the tape machine to the TAPE 2 OUT sockets for

recording.

8. TAPE 1 IN, OUT

Connections for analogue recording and playback to a secondary

audio tape recorder of any type. Using twin RCA-to-RCA leads,

connect to the left and right "Audio Output" of the tape machine

to the TAPE 1 IN sockets for playback and tape monitoring.

Connect the left and right "Audio Input" of the tape machine to the

TAPE 1 OUT sockets for recording.

9. PRE OUT

The NAD C730 allows for the connection of a different or additional

power amplifier. If you are using an external stereo power

amplifier, use a twin RCA-to-RCA lead to connect to the left and

right "Audio Input" of the Power amp to the PRE OUT 1 sockets.

NOTES:

Always turn the C730 and associated external power

amplifiers off before connecting or disconnecting anything to the

PRE-OUT sockets.

The PRE-OUT output signal will be affected by the NAD C730's

volume and tone control settings.

NAD C730 Stereo AM/FM Receiver

8. PRESET/TUNE

The Preset/Tune button toggles between two different modes:

a) Preset mode: In this mode you can use the Tune/Preset

buttons (No. 9) to select a Preset. When Preset Mode

is selected "PRESET" will scroll once through the display and

the PRESET indicator lights up in the display.

b) Tune mode: By pressing the Preset/Tune button (No. 9)

you can engage automatic or manual tuning

respectively down or up the frequency band. When Tune mode

is selected, "TUNE" will scroll through the display once.

9. PRESET/TUNE

AND

The function of these buttons depends on the tuning mode

selected with the Preset/Tune button (No. 8). The Preset/Tune

button toggles between the two operation modes:

a) Preset mode (indicated in the display area): Press the

(down) button to scroll to a lower number Preset; press the

(up) button to scroll to a higher Preset number. This is a

"wrap-around" function, so that going from the highest

number Preset, the tuner will go to the lowest Preset number

or vice-versa when tuning either up or down.

b) Tune mode: Press the

(down) or

(up) button for

more than 1 second to engage automatic tuning respectively up

or down the frequency band. The tuner will search

automatically for the first reasonably strong radio station,

where it will stop. Press the Down/Up button again for 1

second to start searching again.

By briefly tapping the

(down) or

(up) buttons you can

engage manual tuning respectively up or down the frequency band

for precise tuning to a specific frequency. With each successive tap

of the keys, the tuner will take 0.05 MHz steps on FM so you can

accurately tune into the desired frequency. For AM the tuning steps

are set at 10 kHz (120V version) or 9 kHz (230V version).

This tuning mode can also be useful when trying to receive a radio

station, which is too weak for the auto search mode. When tuned

accurately to a station, "TUNED" will light up in the display. The

muting circuit, however may suppress very weak radio station

signals. If such a very weak station is in stereo it will have a high

level of background hiss. Switching to Mono Mode and

disengaging the muting circuit by depressing the FM MUTE/MODE

button (No. 5) will allow the station to be heard and will cancel

most or all of this background noise.

NOTES:

Automatic tuning is available on both FM and AM.

Even if the C730 is in Tune Mode, the remote control's Preset Up

and Down buttons will only change presets.

The Preset/Tune

and

buttons are also used in

conjunction with the Memory (No. 4) and Display (No. 7) buttons

to add and memorise user defined names to Presets. Refer to the

separate chapter "Storing, Recalling and Labelling Presets" for

more information.

10. DISPLAY AREA

The display area gives all vital information on the status of the

receiver. Displayed are:

· Which input is selected

· Volume MUTE On

· Tape Monitor engaged

· Tone Defeat On

· Band and frequency of current station, RDS PS (station name),

or RDS Radio Text. The latter two only if RDS is available; select

using the Display button (No. 7).

· If an FM Stereo broadcast is received.

· If the FM station also broadcasts RDS.

· If "Memory" has been engaged

· Preset number if the current station is stored in the tuner's

memory bank.

· If Blend and FM Mute/Mode are switched On.

· Radio Signal Strength. The bars just below "ANTENNA" indicate

the radio station's signal strength. The more bars are lit, the

stronger the station.

NOTE:

The infrared sensor, which receives commands from a

remote control (not supplied), is located on the left side of the

display window. There must be a clear line-of-sight path from the

remote control to this window; if that path is obstructed, the

remote control may not work.

11. VOLUME

The VOLUME control adjusts the overall loudness of the signals

being fed to the loudspeakers. It is motor driven and can be

adjusted from the remote control handset. The VOLUME control

does not affect recordings made using the Tape outputs but will

affect the signal going to the Pre-amp output (Pre Out).

On the remote control handset, press the MUTE Button to

temporarily switch off the sound to the speakers and headphones.

Mute mode is indicated by "MUTE" flashing in red in the display

area. Press MUTE again to restore sound. Mute does not affect

recordings made using the Tape outputs but will affect the signal

going to the Pre-amp output (Pre Out).

12. HEADPHONE SOCKET

A 1/4" stereo jack socket is supplied for headphone listening and

will work with conventional headphones of any impedance.

Inserting a headphone jack into this socket automatically switches

off the loudspeakers. The volume, tone and balance controls are

operative for headphone listening. Use a suitable adapter to

connect headphones with other types of sockets, such as 3.5mm

stereo "personal stereo" jack plugs.

REMOTE CONTROL

STANDBY/ON button (No.1)

When the receiver is switched On, pressing the green On/Off

button on the remote handset will put the receiver into Standby

mode and the Power indicator will turn amber. The amber Power

indicator shows that power is being supplied, but the system is

currently in the Standby Mode. Press again to switch the receiver

On from Stand-by mode.

ON and OFF buttons (No.2)

Besides the On/Off toggle function of the green button (No. 1), the

NAD C730 remote also has a separate On and Off button. This can

be particularly useful to keep components within a system "in-

sync": This way all components will switch to stand-by when Off is

pressed or switch to operating mode when On is pressed, instead

of some components switching On when the receiver is switched

to Stand-by. (Note that the other components have to be capable

of responding to the separate On and Off commands as well).

Press the ON button to switch the unit from Stand-by to the

operating mode; The Stand-by indicator (Fig. 2; No. 2) will turn

from amber to green to indicate the receiver is ready for use.

Press the OFF button to switch the unit to the Stand-by mode: The

Stand-by indicator will light up amber.

NOTE:

In Stand-by mode the C730 uses very little power.

However, it is recommended that you switch the unit totally off if

it is not going to be used for more than a couple of days. Switch

off completely by pressing the POWER button on the front panel

(No. 1), all lights will extinguish.

2. STAND-BY INDICATOR

This indicator lights up green during normal operation. In Stand-

by mode the indicator will light up amber. Refer to section 1 in

this chapter for more information. The indicator will blink when

the receiver receives a remote control command from the

supplied handset.

If the receiver goes into "protection" mode the Led will flash

continuously at a rate of two flashes per second. This can occur if

there is a short circuit in the speaker wiring. Switch the unit off

totally using the Power button on the front panel (No 1) and

check all the cables and connections both at the receiver side and

at the loudspeakers side. Once all the connections are restored

correctly, switch the Power button (No 1) on, with the volume

initially set low and then resume normal operation. If the problem

persists, switch of the power completely and consult your dealer.

3. BLEND

Weak or remote stereo radio stations are sometimes received with

noise and hiss as the antenna signal is too weak. By switching the

tuner to mono will reduce the amount of noise and hiss but at the

expense of any stereo information. The NAD Blend feature will

allow you to reduce the amount noise and hiss but still retain

some level of stereo separation, instead of mono. The Blend

button toggles between engaging or disengaging the Blend feature;

when engaged, "BLEND" lights up in the display.

NOTE:

The "Blend" status can be stored for individual presets.

Refer to the separate chapter "Storing, Recalling and Labelling

Presets" for more information.

4. MEMORY

The Memory is used to store stations into the Preset Memory bank

and to store user defined names for non-RDS Preset stations. When

Memory is pressed during normal operation, the Preset number

and the red "MEMORY" indicator will flash in the Display Panel. If

no other buttons are pressed within 12 seconds, the receiver will

revert to its previous state. Refer to the separate chapter "Storing,

Recalling and Labelling Presets" for more information.

5. FM MUTE/MODE

This button combines two functions; it switches the receiver's

tuner section from Stereo to Mono and disengages the muting

circuitry at the same time. The muting circuit will mute the tuner

in between radio stations when searching or tuning. This way the

tuning noise is avoided.

The muting circuit however may suppress very weak radio station

signals. If a weak station is in stereo it will have a high level of

background hiss. Switching to Mono Mode and disengaging the

muting circuit by depressing the FM MUTE/MODE button will

allow the station to be heard and will cancel most or all of this

background noise.

In normal operation the mute circuit is engaged, the display

indicates "FM MUTE". Press the FM Mute/Mode button to

disengage the muting circuit and switch from stereo to mono

reception. "FM MUTE" in the display will extinguish. Press the FM

Mute/Mode switch again to return to Auto Stereo FM operation.

NOTE:

The "FM Mute/Mode" status can be stored for individual

presets. Refer to the separate chapter "Storing, Recalling and

Labelling Presets" for more information.

6. AM/FM

The AM/FM button switches the tuner from the AM band to the FM

band and vice-versa. The Display Panel shows the frequency of the

tuned station and which band is selected. The FM tuning is in 0.05

MHz increments, AM tuning is in 9 kHz or 10 kHz increments,

depending on the version.

7. DISPLAY

With stations carrying RDS information, The Display button scrolls

between three different display modes, each successive push of

the button engages the next one of the three modes:

a) In the default mode, the station's RDS name is displayed,

Program Service (PS; normally the station's calling letters, BBC

R3, for instance).

b) From the default mode, press the button once to view Radio Text

(RT). This can be additional information such as the presenter's

or program's name; what song is playing, etc. This text scrolls

continuously over the 8 alphanumeric display segments.

c) Press the button from the display RT mode to display the station

frequency. Press again to return to the default mode (a).

When tuned to a non-RDS station

The Display button toggles the display to show either the station

frequency or user entered station name. If no user name was

entered the display will indicate "NO RDS".

The Display button is also used to label non-RDS stations with a

name. Refer to the separate chapter "Storing, Recalling and

Labelling Presets" for more information.

DELETING A STORED PRESET

You can empty a Preset by deleting the stored information:

· Select the Preset to be emptied.

· Press and hold the Memory button (No. 4) and Display button

(No.7) for two seconds. The preset number and the text

"DELETE" will flash in the display.

· Press only the display button again (within default time of 8

seconds) to confirm you want to delete this preset. The text

"DELETED" and "--" as the Preset number appear in the

display for a couple of seconds.

LABELLING A PRESET

When a station is transmitting RDS information, your NAD C730

will automatically show the station initials. Although the Tuner

automatically shows the frequency of any other AM or non-RDS

Preset station, it also allows you to type in the station name to

make it easier to identify which station is stored in the Memory

Preset. To enter a name:

1) Select the Preset you want to attach a name to.

2) Press and hold the Display button (No. 7) for two seconds. The

first space in the Station Data area of the Display Panel will

flash.

3) Press either the Tune/Preset

(No. 9) button to

scroll and select the first character (see Character list below

for reference).

4) Press Display to move one place to the right to enter the next

desired character.

5) Use the Tune/Preset buttons again to select the next character

in the name.

6) Repeat steps 3 to 5 until name is complete or all eight places

have been filled (up to 8 characters).

7) Press Memory once to finish the labelling procedure. Press

Memory again to store the completed name.

There are 37 characters available including a blank space.

NOTE:

This function is only available for non-RDS stations. RDS

stations will always display their transmitted name and cannot be

over-written.

TO MAKE A RECORDING

When any source is selected, its signal is also fed directly to any

tape machine connected to the TAPE 1 or TAPE 2 OUTPUTS on the

rear panel for recording.

TAPE TO TAPE COPYING

You can copy between two tape machines connected to your NAD

C730. Put the source tape in the recorder connected to Tape 2 and

the blank tape into the recorder connected to Tape 1. By selecting

TAPE 2 Input, you can now record from Tape 2 to Tape 1 and

monitor the signal coming from the original tape.

REMOTE CONTROL HANDSET (FIG 4)

The Remote Control handset handles all the key functions of the

NAD C730 and has additional controls to remotely operate NAD

Tuners, Cassette and CD machines. It will operate up to a distance

of 16ft (5m). Alkaline batteries are recommended for maximum

operating life. Two AAA (R 03) batteries should be fitted in the

battery compartment at the rear of the Remote Control handset.

When replacing batteries, check that they have been put in the right

way round, as indicated on the base of the battery compartment.

Please refer to previous sections of the manual for a full

description of individual functions.

When a command from the remote control is received, the Stand-

by/protection indicator will blink. Note that the indicator may also

blink when receiving commands not necessarily for the C730 but

for other components in the system.

1. STANDBY/ON BUTTON

When the amplifier is switched On, pressing the green On/Off

button on the remote handset will put the NAD-370 into Standby

mode and the Power indicator will turn amber. The amber Power

indicator shows that power is being supplied to the NAD-370, but

the system is currently in the Standby Mode. Press again to switch

the amplifier On from Stand-by mode.

2. POWER ON & OFF

Besides the On/Off toggle function of the green button (No. 1), the

NAD C730 remote also has a separate On and Off button. This can

be particularly useful to keep components within a system "in-

sync": This way all components will switch to stand-by when Off is

pressed or switch to operating mode when On is pressed, instead

of some components switching On when the amplifier is switched

to Stand-by. (Note that the other components have to be capable

of responding to the separate On and Off commands as well).

Press the ON button to switch the unit from Stand-by to the

operating mode; The Stand-by indicator (Fig. 2; No. 2) will turn

from amber to green and the indicator for the last selected input

will blink and light up. Press the OFF button to switch the unit to

the Stand-by mode: The Stand-by indicator will light up amber.

3. SPEAKERS A & B

These buttons are inoperative on the C730

4. MUTE

Press the MUTE Button (No. 4) to temporarily switch off the sound

to the speakers and headphones. Mute mode is indicated by

"MUTE" flashing in red in the display area. Press MUTE again to

restore sound. Mute does not affect recordings made using the

Tape outputs but will affect the signal going to the Pre-amp output

(Pre-Out).

5. INPUTS

The input selector buttons (No. 5) perform the same functions as

the buttons labelled the same on the front panel. There are a few

differences and extra functions with the remote control handset

however:

The TUNER AM & FM buttons select the Tuner input and

respectively the AM or FM waveband. The receiver will tune to the

last station selected on either AM or FM band.

NOTE:

The Video 2 and Video 3 input selector buttons are

inoperative.

13. INPUT SELECTORS

These buttons select the active input to the NAD C730 and the

signal sent to the loudspeakers, the Tape outputs and the PRE OUT

sockets. The buttons on the remote control handset duplicate

these buttons, with the exception of the tuner input; see below.

The display indicates which input has been selected.

DISC Selects a line-level source connected to the DISC sockets as

the active input.

CD Selects the CD (or other line-level source) connected to the

CD sockets, as the active input.

VIDEO Selects the VCR (or stereo TV/Satellite/Cable receiver)

connected to the VIDEO sockets, as the active input.

AUX Selects a line-level source connected to the AUX sockets, as

the active input.

TUNER Selects the tuner as the active input. The receiver will

return to the last selected preset or frequency. The remote control

handset has separate buttons for AM and FM; pressing either one

will select the tuner as the active input and revert to the last station

tuned to on respectively the AM or FM band.

TAPE 2 Selects Tape 2 as the active input.

TAPE 1 Monitor Selects the output from a tape recorder when

playing back tapes or monitoring recordings being made through

the Tape 1sockets. Press the Tape 1 button once to select it and

again to return to the normal input selection.

Tape 1 is a tape Monitor function which does not override the

current input selection. For example, if the CD is the active input

when TAPE 1 is selected, then the CD signal will continue to be

selected and sent to both the TAPE 1, and TAPE 2 OUTPUT sockets,

but it is the sound from recorder connected to Tape 1 that will be

heard on the loudspeakers. When Tape 1 Monitor is selected,

"TAPE 1" is indicated in the alphanumeric section of the display

for 3 seconds before it defaults to indicating the active input again.

The red box next to the preset number section in the display

indicating "TAPE MONITOR" will remain lit until Tape 1 is

disengaged again.

NOTE:

The remote control handset with the C730 supplied is of a

universal NAD type, designed to operate several NAD models. Some

buttons on this handset are inoperative as the functions aren't

supported by the C730. The Video 2, Video 3 input selector

buttons, tuner Bank button, speakers A and Speakers B buttons on

the remote control handset are inoperative in the case of the C730.

NOTE:

Make certain that the volume control is turned to

minimum (fully anti-clockwise) before connecting or

disconnecting headphones. Listening at high levels can damage

your hearing.

14. BASS & TREBLE CONTROLS

The NAD C730 is fitted with BASS and TREBLE tone controls to

adjust the tonal balance of your system.

The 12 o'clock position is "flat" with no boost or cut and a detent

indicates this position. Rotate the control clockwise to increase

the amount of Bass or Treble. Rotate the control anti-clockwise to

decrease the amount of Bass or Treble. The Tone controls do not

affect recordings made using the Tape outputs but will affect the

signal going to the Pre-amp output (Pre Out).

15. TONE DEFEAT

The TONE DEFEAT switch by-passes the tone control section of the

NAD C730. If the Tone Controls are not normally used and left in

the 12 o'clock position, then it is advisable to switch out the Tone

Control section altogether by using this switch. In the "out"

position, the Tone Control circuits are active, pushing the TONE

DEFEAT switch "in" bypasses the Tone Control section.

16. BALANCE

The BALANCE control adjusts the relative levels of the left and right

speakers. The 12 o'clock position provides equal level to the left

and right channels. A detent indicates this position.

Rotating the control clockwise moves the balance towards the

right. Rotating the control anti-clockwise moves the balance to the

left. The BALANCE control does not affect recordings made using

the Tape outputs but will affect the signal going to the Pre-amp

output (Pre Out).

STORING, RECALLING

AND LABELLING PRESETS

Up to 30 presets in total can be stored in the C730's memory bank;

these can be any mix of either AM or FM stations. When scrolling

through the presets, empty preset places will be skipped; it is thus

possible to go from preset No. 4 to No. 7 without having seen No.

5 and 6. With the presets you can also store whether you want

Blend (No. 3) and FM Mute/Mode (No. 5) to be activated as well

every time you recall the preset.

TO STORE A PRESET

· Tune to the radio station you wish to enter into a Preset (refer

to this chapter's section 9). If the station is transmitting RDS

information, the RDS indicator will light up and station initials

or name will be shown in the Display Panel. If a non-RDS

station is found, then just the frequency will be shown.

· Select Blend (No. 3) or FM Mute/Mode (No. 5) if desired.

· To store that station as a Preset, press Memory (No. 4). The

Preset number and the red "MEMORY" indicator are flashing

in the Display Panel. The lowest available empty preset number

will be shown. If no other buttons are pressed within 8

seconds, the tuner will revert to its previous state.

· Press Memory again to store the preset. If you wish to assign a

different preset number, press either the Preset/Tune

button to select the desired preset number. You can over-

write an existing preset. If the preset number already has been

assigned, "MEMORY" will stop blinking, but the preset will

continue to blink. When you have selected the desired preset

number, press Memory again to store the station.

NOTES:

You can enter a new station into an unused Preset or

over-write an existing programmed Memory Preset. By doing this

you will replace all the data previously held on that Preset number.

When Memory is pressed during normal operation, the Preset

number and the red "MEMORY" indicator will flash in the Display

Panel. If no other buttons are pressed within 8 seconds, the tuner

will revert to its previous state. The Memory Presets have a memory

back-up, so they will remain stored for several weeks even if the

Tuner is switched off or unplugged from the mains supply.

RECALLING A PRESET

· To select a Preset station, check if Preset mode is engaged (the

display indicates "PRESET"). If not, press the Preset/Tune

Mode button (No. 8); "PRESET" will now light up in the

display.

· Press either the Preset/Tune

buttons (No. 9)

until the right Preset is found and shown in the Display Panel.

Any unused Presets will be skipped; this avoids having to scroll

through empty presets.
