information.
NOTE:
always turn the pre-amplifier and associated power
amplifiers off before connecting or disconnecting anything to the
Pre-Out 1 & 2 sockets.
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 C160'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
C160 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 C160'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 C160.
