QUICK START
1. Connect the RCA or XLR outputs to a power amplifier or active
loudspeakers.
2. Plug in the AC Mains cable.
3. Press the POWER button to turn the S100 on.
4. Press the required input selector.
NOTES ON INSTALLATION
Your S100 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 as a
bookcase or cabinet that may impede the airflow through the
ventilation slots.
Switch the unit and all ancillary equipment off before making any
connections. The RCA connectors on your S100 are colour coded for
convenience. Red and white are Right and Left audio respectively,
and yellow for NAD-Link.
The S100 comes with RCA leads for basic connections. Where
additional leads are required, use high quality leads and connectors
for optimum performance and reliability. Ensure that leads and
connectors are not damaged in any way and all connectors are firmly
pushed home. If the unit is not going to be used for some time,
disconnect the plug from the AC socket.
Should water get into your S100, 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
1. IEC AC MAINS (POWER) INPUT
The S100 comes supplied with a separate AC Mains cable. Before
connecting the cable to a live wall socket ensure that it is firmly
connected to the NAD S100's AC Mains input socket first. Always
disconnect the AC Mains cable plug from the live wall socket first,
before disconnecting the cable from the S100 Mains input socket.
Voltage conversion:
A notice printed on the rear indicates the AC power-line voltage that
the preamplifier requires. However, every model S100 amplifier has a
"universal" power supply that can be modified easily for operation in
other countries. If you wish to transport your S100 to a nation that
employs a different power-line voltage, an authorised NAD dealer or
service agency can convert it for such use.
2. PHONO/AUX2 INPUT
The NAD S100 preamplifier may be fitted with a dedicated Phono
Module to allow for direct connection of phono Moving Magnet
(MM) or Moving Coil (MC) cartridges.
Depending on your version of the NAD S100 preamplifier, it may
already be fitted with the dedicated S100 Phono Module. The S100
Phono Module can be retro-fitted by your dealer who can also set
the parameters (such as MM or MC, MC cartridge impedance) of the
Phono Module to suit your specific turntable and cartridge
combination.
Without the S100 Phono Module:
Without the module installed, the PHONO/AUX2 input provides an
additional line-level input such as an additional CD player, MD player,
etc. Use a twin RCA-to-RCA lead to connect the auxiliary unit's left
and right `Audio Outputs' to these inputs.
NOTE: Without the Phono Module only a very faint sound will be
heard if a turntable fitted with an MM or MC cartridge is connected.
Consult your dealer to have the optional Phono Module fitted.
With the S100 Phono Module:
Ensure that your dealer has chosen the correct settings inside the
Phono Module (MM or MC, cartridge impedance) to suit your
specific turntable and cartridge combination. Connect the twin RCA
lead from your turntable, observing that the left and right channels
are connected correctly.
3. PHONO GROUND CONNECTOR
Apart from the twin RCA lead, most turntables also include a single
wire earth lead. Connect this to the S100 chassis PHONO GROUND
connector.
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 left and right `Audio Outputs' to these
inputs. The S100 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
Outputs' of the unit to these inputs.
NOTE: These are audio inputs only.
6. AUX 1 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 these inputs.
7. 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
these inputs.

tape recorder of any type. Using twin RCA-to-RCA leads, connect to
the left and right `Audio Outputs' of the tape machine to the TAPE 2 IN
connectors for playback. Connect the left and right `Audio Inputs' of
the tape machine to the TAPE 2 OUT connectors for recording.
9. 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 Outputs' of the tape machine to the TAPE 1 IN
connectors for playback and tape monitoring. Connect the left and
right `Audio Inputs' of the tape machine to the TAPE 1 OUT
connectors for recording.
10. PRE 1, PRE 2 OUT (UNBALANCED)
Connections for an external power amplifier, processor or active
speakers. Use twin RCA-to-RCA leads to connect to the left and right
`Audio Inputs' of the power amplifier, processor or active speakers to
the PRE 1 or PRE 2 OUT connectors.
The PRE 1 and PRE 2 OUT sockets carry the same signal and may be
used simultaneously for e.g. bi-amping.
The PREOUT output signal is controlled by the S100's volume and
balance control settings. These sockets provide connections to
amplifiers, active speakers and processors requiring an unbalanced
RCA connections.
11. BALANCED OUTPUT
Connections to an external power amplifier or processor that uses
balanced XLR connectors. These are fully balanced XLR outputs,
suitable to drive most balanced hi-fi and professional amplifiers.
The wiring standard used for these connectors is:
Pin 1
Chassis Earth (Ground)
Pin 2
Hot (Live )
Pin 3
Signal Ground (Return)
12. NAD-LINK IN, OUT
The NAD-Link connector is used to pass commands from the remote
control 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
S100'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 Room systems.
FRONT PANEL CONTROLS
1. POWER
Pressing the POWER button turns the unit On and after a few
seconds, the Power indicator LED will extinguish. Pressing the
POWER button again will turn the preamplifier Off.
When the S100 is switched On, pressing the Standby button on the
remote handset will put the S100 into Standby mode and the Power
indicator will light up blue. The blue Standby indicator shows that
power is being supplied to the S100, but the system is currently in
the Standby mode.
CAUTION: When in Standby mode, power is still supplied to your
S100. You should switch it Off using the front panel POWER button
when it is not being used for long periods of time.
2. REMOTE SENSOR
Sensor for receiving the infrared signals from your remote control
handset. The LED above the sensor flashes to confirm infrared
reception.
3. INPUT SELECTORS
These buttons select the active input to the S100 and the signal sent
to the TAPE outputs, the PRE 1 & PRE 2 OUT and XLR output sockets.
LEDs over each button will indicate which input is currently selected.
PHONO/AUX 2 Selects the source connected to the PHONO/AUX 2
input. With the optional S100 Phono Module installed, a turntable
Phono with either an MM or MC cartridge can be connected.
Without the optional Phono Module installed you can use this input
for any line-level source.
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 VCR sockets as the active input.
AUX 1 Selects a line-level source connected to the AUX sockets as
the active input.
TUNER Selects the tuner (or other line-level source) connected to the
Tuner sockets as the active input.
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 1 sockets. Press the TAPE 1 MONITOR button once to select it
and again to return to the normal input selection.
TAPE 1 MONITOR is a tape monitor function which does not override
the current input selection. For example, if CD is the active input
when TAPE 1 MONITOR 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 the recorder connected to TAPE 1
that will be heard on the loudspeakers.
To show which input is active in when in tape monitor mode, its
indicator light will stay lit.
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 for recording.
TAPE TO TAPE COPYING
You can copy between two tape machines connected to your S100.
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 source tape.
Also you can use TAPE 1 as the source and copy to TAPE 2 but TAPE
1 MONITOR Input has to be selected for the duration of the
recording.
CAUTION: WHEN TAPE 2 IS SELECTED, ONLY ONE TAPE MACHINE
SHOULD BE SET IN RECORD MODE. IF BOTH ARE SET IN RECORD
MODE, WITH TAPE 2 SELECTED, A FEEDBACK LOOP RESULTS
WHICH MAY CAUSE A LOUD "WHISTLE" OR "HOWL" ,
POTENTIALLY DAMAGING YOUR AMPLIFIER OR LOUDSPEAKERS.
