nac 112 operation
power supplies
The nac 112 does not incorporate an internal power supply. It must be used in conjunction with either
a naim power amplifier incorporating a preamp power supply or with a supercap, hi-cap or flatcap 2
power supply.
inputs
The nac 112 has 6 inputs -
cd, tuner, tape, A/V, aux 1
and
aux 2
. The
tape, a/v
and
aux 1
all have
record output facilities for a cassette deck or VCR, etc. The
aux 2
input is provided with two sockets.
Use the right hand socket (when viewed from the rear) for connecting conventional ancillary
equipment. The extra (left hand) socket is for use with separate phono stage, such as the Prefix or
Stageline or a Headline headphone amplifier. Only one of the
aux 2
sockets may be used at a time -
damage may result if both sockets are used simultaneously. As supplied, the nac 112 has a protective
cover fitted over the extra socket. If this socket is to be used it is advisable to refit the protective cover
over the unused socket.
tape and monitor functions
The tape monitor (mon) button allows the output of a 3-head tape machine to be heard while
recording in order to check the “off-tape” signal. The source for recording is chosen by the input
selector buttons in the normal way.
Pressing the monitor button during recording allows the output from a 3-head tape machine
connected to either tape, A/V or AUX 1 to be heard. After pressing “mon”, select whichever one of
these your tape machine is connected to. A second press of the monitor button returns the amp to
normal position.
mute function
Pressing the mute button reduces the output from the loudspeakers to zero. (This will not affect any
recordings taking place at the same time).
channel balance
Channel balance adjustment on the nac 112 is operated electronically within the amplifier and is
controlled by the remote handset only. Please see the handset instructions on pages 18 and 19.
input level adjustment
Each nac 112 input can be adjusted so that the volume level from each source is similar in normal use.
The remote handset controls and enables this function. Please see the handset instructions on pages
18 and 19.
remote control
For operation of the nac 112 with the NARCOM 2 remote handset please see pages 18 and 19.
Note: As there is no mono facility available on the nac112, the “mono” facility on the remote handset
operates the tape monitor circuit.
