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 volt-
age surges and built-up static charges. Section 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 dis-
charge unit, connection to grounding electrodes and requirements for the
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
d. Use jumper wire not smaller than No.6 AWG (13.3mm2) copper, or the equiva-
lent, when a separate antenna-grounding electrode is used. see NEC Section

NOTES ON INSTALLATION.
Your NAD 317 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 it in an
enclosed position such a bookcase or cabinet that
may impede the air-flow through the ventilation slots.
Switch the unit off before making any connections.
The RCA connectors on your NAD 317 are colour
coded for convenience. Red and white are Right and
Left audio respectively, and yellow for NAD-Link.
The NAD 317 comes with RCA leads for basic con-
nections. Where additional leads are required, use
high quality leads and connectors for optimum perfor-
mance and reliability. Ensure that leads and connec-
tors are not damaged in any way and all connectors
are firmly pushed home.
For best performance, use quality speaker leads of
16 gauge 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 317, 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-ser-
viceable parts inside.
Use a dry soft cloth to clean the unit. If necessary,
lightly dampened the cloth with soapy water. Do not
use solutions containing benzol or other volatile
REAR PANEL CONNECTIONS.
1. CD INPUT

a twin RCA-to-RCA lead to connect the CD player left
and right `Audio Outputs' to this input. The NAD 317
only accepts analogue signals from your CD player.
2. 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.
3. TUNER INPUT
Input for a Tuner or other line-level signal source.
Use a twin RCA-to-RCA lead to connect the Tuner
left and right `Audio Outputs' to this input.
4. 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.
5. TAPE 1 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 1 IN
connectors for playback and tape monitoring.
Connect the left and right `Audio Input' of the tape
machine to the TAPE 1 OUT connectors for record-
6. TAPE 2 IN, OUT

Connect the left and right `Audio Input' of the tape
machine to the TAPE 2 OUT connectors for record-
7. PRE OUT, MAIN IN
Connections to an external pre-amplifier, power
amplifier or processor, such as a surround-sound
decoder. In normal use these should be connected
together using the links supplied. To connect your
NAD 317 to external processor or amplifier sections
first remove these links. Use a twin RCA-to-RCA lead
to connect to the left and right `Audio Input' of the
Power amp or processor to the Pre Out connectors.
Connect the left and right `Audio Output' of the Pre-
amp or processor to the Main In connectors.
Note: The Pre-Out output signal will be affected by
the NAD 317's volume and tone control settings.
8. NAD-LINK IN, OUT
The NAD-Link connector is used to pass com-
mands from the remote control handset to and from
other units fitted with NAD-Link connectors. This
allows centralised control of a complete system or
gives system control from more than one room. To
function with other units, connect the NAD 317'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.
A single NAD-Link connection from a hi-fi system in
a second room will allow remote control of Multi
Speaker terminals for speakers with an impedance
of 4 ohms or more.
Connect the right speaker to the terminals marked
`R +' and `R-' ensuring that the `R+' is connected to
the `+' terminal on your loudspeaker and the `R-' is
NAD 317 STEREO AMPLIFIER
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 or thicker)
stranded wire to connect loudspeakers to your NAD
The high-current binding post terminals can be
used as a screw terminal for cables terminating in
spade or pin connectors or for cables with bare wire
These should be slotted under the terminal's screw
bushing, which is then fully tightened. Ensure the
connector is tightly secured and there is no danger of
bare metal from spade connectors touching the back
panel or another connector, as this may cause dam-
BARE WIRES AND PIN CONNECTORS
Bare wires and pin connectors 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.
Avoid any danger of bare metal from the speaker
cables touching the back panel or another connector.
Ensure that there is only 1/2" (1cm) of bare cable or
pin and no loose strands of speaker wire.
10. SOFT CLIPPING
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 cut-
ting off or `hard clipping' the peaks of sound that it
was not designed to reproduce. The NAD Soft
Clipping circuit gently limits the output of the system
to minimize audible distortion if the amplifier is over-
If your listening involves moderate power levels you
may leave the Soft Clipping switch to Off. If you are
likely to play at high levels, that could stretch the
amplifier's power capability, then switch Soft Clipping
The Soft Clipping LED on the front panel will illumi-
nate when the amplifier is in Soft Clipping mode.
11. BRIDGE SWITCH
The NAD 317 can be used as part of a higher
power stereo or home-theatre system, by connecting
additional power amplifiers. If the power amp section
in the NAD 317 is to be used to drive a single speak-
er, then use the Bridge switch to run the left and right
power amplifiers as a single channel, high power unit.
Set the Bridge switch to the `Bridge' position and con-
nect the speaker to the terminals marked `L +' and
`R+' ensuring that the `L+' is connected to the `+' ter-
minal on your loudspeaker and the `R+' is connected
to the loudspeaker's `-' terminal. In Bridged mode left
channel is taken as the input and the NAD 317 will
produce approximately 240W into an 8 ohm loud-
speaker. In this mode, the amplifier sections will react
as though the speaker impedance has been halved.
So speakers with very low impedances (under 4 )
are not recommended as they may cause the amplifi-
er's thermal cut-out to operate if played at high levels.
The Bridge LED on the front panel will illuminate
when the amplifier is in Bridge mode.
12. AC LINE CORD.
After you complete all connections to the preampli-
fier, plug the AC line cord into a "live" AC socket.
13. AC CONVENIENCE OUTLETS (U.S.
CANADIAN MODELS ONLY
The AC power cords of other units in the audio
system can be connected directly to the AV 711's
unswitched AC outlets. If another stereo component
is plugged into the UNSWITCHED AC outlet, power
will be supplied whether your AV711 is on or off.
FRONT PANEL CONTROLS.
POWER, SPEAKERS AND HEADPHONE
Pressing the POWER switch turns the unit On and
after a short pause, the Power indicator LED will illu-
minate green. Pressing the POWER switch again will
turn the amplifier Off.
When the NAD 317 is switched On, pressing the
Standby button on the remote handset will put the
NAD 317 into Standby mode and the Power indicator
will turn amber. The amber Power indicator shows
that power is being supplied to the NAD 317, but the
system is currently in the Standby Mode.
CAUTION: When in Standby, power is still supplied
to your NAD 317. You should switch it off using the
front panel Power switch when it is not being used for
long periods of time.
2. 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 loudspeak-
ers. The volume and tone and balance controls are
operative for headphone listening. Use a suitable
adapter to connect headphones with other types of
connectors, such as 3.5mm stereo `personal stereo'
Warning: Make certain that the volume control is
turned to minimum (fully anti-clockwise) before con-
Listening at high levels can damage your hearing.
3. BASS & TREBLE CONTROLS
The NAD 317 is fitted with BASS and TREBLE tone
controls to adjust the tonal balance of your system.
