14. 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 pre-amplifier's remote control.
To function with such other units, connect the C 162'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.
15. 12V TRIGGER OUT
The 12V trigger is activated automatically when switching the NAD
C 162 from off or stand-by to on. Connect the 12V trigger to a power
amplifier or AC outlet power strip equipped with a 12V trigger input for
remote on/off switching of those devices. Use a cable terminated with
a 3.5mm Mini-Jack connector at the pre-amplifier's end for connection.
16. 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.
17. SWITCHED AND UNSWITCHED POWER OUTLETS
(AH VERSION ONLY)
The AC power cords of other stereo components, such as a CD player,
may be plugged into these accessory outlets. Components plugged into
the outlet marked "switched" will be switched on and off as the pre-
amplifier is switched from stand-by or off to on and vice versa.
Mains power is always available on the outlet marked "unswitched" as
long as the NAD C 162's power cord is plugged into a live AC wall
outlet. This outlet can be used for components which may require
continuous supply of AC mains; some tuners require uninterrupted
mains supply to retain preset memory, for instance.
NOTE
The total power consumption of any components connected to the
AC outlets may not exceed 100 Watts. Never connect the mains
lead of a power amplifier to either the Switched or Unswitched
outlets of the NAD C 162.
QUICK START
1 Connect a twin RCA lead to a power amplifier.
2 Connect the desired sources to the relevant input sockets on the
rear.
3 Connect speakers to the power amplifier.
4 Plug in the AC power cord.
5 Press the POWER button to turn on the NAD C 162.
6 Switch on the power amplifier
7 Press the required input selector.
FRONT PANEL CONTROLS
1. POWER ON/OFF
Press the POWER button to switch the pre-amplifier to its `Stand-by'
mode. The Stand-by indicator (No. 2) over the power button will light
up amber. On the front panel, press any of the input selector buttons to
switch to pre-amplifier on. From the remote control, press the POWER
ON button to switch the unit on. The Stand-by indicator will turn from
amber to green to indicate it is switched on and ready for use.
NOTE
In Stand-by mode the C 162 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. POWER/STAND-BY
The indicator LED offers information on the status of the NAD C 162:
Off: The unit is switched off totally.
Amber: The unit is in stand-by mode
Green: The unit is switched on and ready for use.
The LED will also flash when the pre-amplifier receives a remote control
command from the supplied handset.
3. 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 output to
the PRE OUT 1 & 2 sockets on the back panel. 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.
NOTE
Listening at high levels can damage your hearing.
4. INFRA-RED REMOTE CONTROL COMMAND RECEIVER
The infrared sensor, located behind this circular window, receives
commands from the remote control. 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.
