QUICK START
Use the RCA-to-RCA lead to connect the S400 left & right outputs to
the tuner inputs of your amplifier.
1. Plug in the AC Mains cable.
2. Connect FM antenna.
3. Connect S400 outputs to amplifier.
4. Press the POWER button to turn on the S400.
5. Select antenna input to which aerial is connected.
6. Press TUNE or for one second to activate Search mode.
7. When a station is found, search will stop.
NOTES ON INSTALLATION
Your S400 should be placed on a firm, level surface. Avoid placing
the unit in direct sunlight, near sources of heat and damp or in
poorly ventilated positions.
It comes with RCA leads for connection to your amplifier. 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 S400, shut off the power to the unit
and remove the AC Mains cable from the AC socket. Have the
unit inspected by a qualified service technician before attempting
to use it again.
Do not open the tuner or attempt to modify or repair it
yourself. Refer all servicing to a qualified technician. 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. FM ANTENNA
The S400 is equipped with two antenna connectors to allow you to
connect simultaneously to for example a cable network and an
outdoor aerial.
A ribbon wire FM antenna is included in order to permit reception
even if no outdoor antenna or cable is available. It should be
connected to one of the FM connectors at the rear of the unit using
the ‘balun’ adapter supplied. See Figure 1.
The ribbon aerial should be mounted on a vertical surface and placed
so that it forms a ‘T’. Experiment with placement of the indoor
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
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. OUTPUT
Using twin RCA-to-RCA leads, connect the Left (white) and Right
(red) audio outputs to the ‘Tuner’ input or other line-level input such
as ‘Aux’ input of your amplifier.
3. 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 the
S400 to be controlled using a NAD-Linked amplifier’s remote control
or gives system control from more than one room. To function with
such other units, connect the Tuner’s NAD-Link IN to the NAD-Link
OUT 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.
4. IEC AC MAINS INPUT
The S400 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 S400’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 S400 Mains input socket.
FRONT PANEL CONTROLS
1. POWER ON/OFF
Press this button to switch on the power to the S400. Press again
and release to switch the power off. The display window lights up
when power is ON. The blue LED above the POWER button lights up
briefly when ON/OFF is activated, but it goes out again immediately.
The blue LED lights up permanently only to indicate stand-by if the
unit is turned off from an NAD system remote control with STANDBY
button. If this option is used, the S400 may be switched on again by
pressing the STANDBY button of the system remote, or by pressing
and releasing the POWER button on the front of the S400 to switch
it off, and then press it again to switch it on. Please note that the
remote control which comes with the S400 does not feature a
STANDBY button.
The S400 uses a non-volatile memory to store preset information.
This information is retained even if the unit is switched off
completely or unplugged.
NOTE: When switching power On, the S400 will go back to the
station last tuned to before the unit was turned off. This will allow
you to make timer recordings using an external timer and recorder.
2. MONO/MUTE
Switches between Stereo mode with Muting (Mute) on and Mono
mode with Muting off. Muting suppresses stations that are too weak
to be received well. If Muting is switched off, even very weak
stations may be heard. As these will always be too weak for stereo
reception, Mono is activated simultaneously. The first press of the
button shows Mute On or Off as well as Stereo or Mono in the
display panel. Press Mute again within approx. five seconds to turn
Muting off (or on) and at the same time switch from stereo to mono.
