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.
