NOTES ON INSTALLATION
Your NAD-712 should be placed on a firm, level
surface. Avoid placing the unit in direct sunlight or
near sources of heat and damp.
Allow adequate ventilation. Do not place the unit on
a soft surface like a carpet. Do not place it in an
enclosed position such a bookcase or cabinet that
may impede the air-flow through the ventilation slots.
Switch the unit off before making any connections.
The RCA connectors on your NAD-712 are colour
coded for convenience. Red and white are Right and
Left audio, and orange for NAD-Link.
Use high quality leads and connectors for optimum
performance and reliability of connection. Ensure that
leads and connectors are not damaged in any way
and all connectors are firmly pushed home.
For best performance, use quality speaker leads of
16 gauge thickness or more.
If the unit is not going to be used for some time,
disconnect the plug from the AC socket.
Should water get into your NAD-712, shut off the
power to the unit and remove the plug from the AC
socket. Have the unit inspected by a qualified service
technician before attempting to use it again.
Do not remove the cover, there are no user-ser-
viceable parts inside.
Use a dry soft cloth to clean the unit. If necessary,
lightly dampened the cloth with soapy water. Do not
use solutions containing benzol or other volatile
agents.
REAR PANEL CONNECTIONS
1. FM ANTENNA
A ribbon wire FM antenna is included and should
be connected to the FM connector at the rear of the
unit using the ‘balun’ adapter supplied. (see fig. 1)
The ribbon aerial should be mounted on a vertical
surface and placed so that it forms a ‘T’.
Experiment with placement of the 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 sec-
tion’s 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. AM ANTENNA
An AM wire antenna is supplied with the NAD-712
and is required for AM reception. Open the clip termi-
nal lever and insert the wire from the antenna. (see
fig. 2). Closing the lever will lock the wire in place.
Test various positions for the antenna, but always
ensure the loop is placed vertically for best reception.
Placing the antenna vertically close to large metal
items such as metal shelves or radiators may inter-
fere with reception.
3. TAPE 2 IN/OUT
Connections for analogue recording and playback
to a secondary audio tape recorder of any type. Using
twin phono-to-phono leads, connect to the left and
right ‘Audio Output’ of the tape machine to the TAPE
2 IN connectors for playback. Connect the left and
right ‘Audio Input’ of the tape machine to the TAPE 2
OUT connectors for recording.
4. CD INPUT
Input for CD or other line-level signal source. Use a
twin phono-to-phono lead to connect the CD player
left and right ‘Audio Outputs’ to this input. The NAD-
712 only accepts analogue signals from your CD
player.
5. AUX INPUT
Input for additional line level input signals such as
another CD player. Connect the auxiliary unit’s left
and right ‘Audio Outputs’ to this input.
6. LD INPUT
Laser Disc input for the audio signal from a Laser
Disc or other line-level source such as Video-CD,
computer systems or games consoles. Using twin
phono-to-phono leads, connect to the left and right
‘Audio Out’ of the unit to these inputs.
7. VIDEO SOUND
Input for audio playback from a VCR or other video
device such as a satellite or cable receiver. Using twin
phono-to-phono leads, connect to the left and right
‘Audio Out’ of the VCR/satellite receiver to these
inputs.
8. TAPE 1 IN/OUT
Connections for analogue recording and playback to
an audio tape recorder of any type. Using twin phono-
to-phono leads, connect to the left and right ‘Audio
Output’ of the tape machine to the TAPE 1 IN connec-
tors for playback and tape monitoring. Connect the left
and right ‘Audio Input’ of the tape machine to the
TAPE 1 OUT connectors for recording.
9. PRE OUT, MAIN IN
Connections to an external pre-amplifier, power
amplifier or processor, such as a surround-sound
decoder. In normal use these should be connected
together using the links supplied. To connect your
NAD-712 to external processor or amplifier sections
first remove these links. Use a twin phono-to-phono
