nac 52 operation
power supplies
The nac 52 does not incorporate an internal power supply and can be used only in conjunction with a
supercap power supply.
listening and recording
The input selector buttons are arranged along the uppermost bank of buttons. They control which
source is to be routed to the power amplifier and the loudspeakers, for listening. Below them, in the
lower bank, are a corresponding array of buttons which choose the source component to be routed to
the preamplifier’s recording outputs. One component (for example, the record player) can therefore be
listened to whilst the output from another (say, the tuner) can be recorded onto a tape recorder. It is
possible to lock the record controls and prevent accidental de-selection during recording. Record-lock
is switched on or off by depressing the
source
mono button four times within six seconds.
mute and mono facilities
To the left of each bank of buttons there are two further buttons labelled mute and mono. These work
independently: for example the mute button in the lower (recording) bank does not affect the signal
that is chosen via the upper (source) buttons, and vice versa. Operating the mono button on the source
bank will not affect the record circuits. To select either function press the relevant button once. To
cancel that function press the button again.
preamplifier inputs
Input 1
is a high level input, but can be converted into a phono input by fitting plug in boards. Please
see your dealer for further details.
Input 2
is a standard high level input. Before using, see the section “input socket 2” below.
Input 3
is a standard high level input.
Inputs 4, 5
and
6
are standard high level inputs and also have record output facilities, so these should
be assigned to your tape recorder, cassette deck or VCR.
input socket 2 to expand input capabilities
Please note that input 2 is provided with two sockets. Use socket 2a for connecting your usual
ancillary equipment. The extra socket (2b) is for the Prefix or Stageline phono stage. Only one of these
sockets may be used at a time, for safety as well as performance. Your preamplifier will have a
protective cover fitted over the extra socket. If you wish to use it, it is advisable to refit the protective
cover over the socket that will now be unused, to prevent mistakes.
remote control
For operation of the nac 52 using the NARCOM 2 remote handset please see pages 18 and 19
