NOTES ON INSTALLATION.

Your AV 711 should be placed on a firm, level
surface. Avoid placing the unit in direct sunlight, near
sources of heat and damp or in poorly ventilated
positions.
Switch the unit to off before making any
connections. The phono connectors on your AV 711
are colour coded for convenience. Red and white are
Right and Left audio, yellow is composite (line) video
and NAD-Link.
Use high quality leads and connectors for optimum
performance and reliability of connection. Audio
phono leads will function correctly for video signals,
although it is recommended to use dedicated video
leads where possible. Ensure that leads and connec-
tors are not damaged in any way and all connectors
are firmly pushed home.
For best performance use quality speaker leads of
at least 16 gauge thickness.
If the unit is not going to be used for some time,
disconnect the plug from the AC socket.
Should water get into your AV 711, 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 dampen the cloth with soapy water. Do not use
solutions containing benzol or other volatile agents.
REAR PANEL CONNECTIONS
1. CD INPUT
Input for CD player (analogue audio signal) 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.
2 AUX INPUT
Input for audio components. Use a twin phono-to-
phono lead to connect the audio component left and
right 'Audio Outputs' to this input.
3. TAPE 1
Connections for analogue recording and playback
to an audio tape recorder of any type, such as a
cassette, reel-reel, DAT, MD or DCC. Using twin
phono-to-phono leads, connect to the left and right
'Audio Output' of the tape machine to the TAPE 1 IN
connectors for playback. Connect the left and right
'Audio Input' of the tape machine to the TAPE 1 OUT
connectors for recording.
4. TAPE 2
Connections for analogue recording and playback
to a second 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.

5. VIDEO 1 (AUDIO)
Inputs for the audio playback from a VCR or other
video device such as a stereo TV, satellite or cable
TV receiver or a Laser Disc. Using twin phono-to-
phono leads, connect to the left and right 'Audio Out'
of the VCR/TV/LD/satellite receiver to these inputs.
These audio inputs are used in conjunction with the
composite (line) video inputs marked VIDEO 1.
VIDEO 1 is used for playback only, use VIDEO 2 if
you want to connect a VCR for recording and play-
back through the AV 711.
6. VIDEO 2 (AUDIO)
Connections for the audio recording and playback
to a VCR or other video recorder. Using twin phono-
to-phono leads, connect to the left and right 'Audio
Out' of the VCR to the VIDEO 2 IN connectors for
playback. Connect the left and right 'Audio In' of the
VCR to the VIDEO 2 OUT connectors for recording.
These audio inputs are used in conjunction with the
composite (line) video inputs marked VIDEO 2 IN and
the video outputs marked VIDEO 2 OUT.
7. SUB WOOFER OUT
Additional line output for connection to a sub-bass
speaker system with its own power amplifier.
8. AM ANTENNA
An AM loop antenna is supplied with the AV 711
and is required for AM reception. Open the clip
terminal lever and insert the wire from the antenna.
Closing the lever will lock the wire in place (Fig. 2). If
your AV 711is a U.S.A. or Canadian model, while
pressing down the lever, insert the wire. Release the
lever to 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
close to large metal items such as metal shelves or
radiators may interfere with reception.
9. FM ANTENNA
A ribbon wire FM antenna is included and should
be connected to the FM connector at the rear of the
unit (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
section'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.
10. SOFT CLIPPING
When an amplifier is driven beyond it's specified
power output, a hard distorted sound can be heard on
very loud sounds. This is caused by the amplifier cut-
ting off or 'hard clipping' the peaks of sound that
was not designed to reproduce. The NAD Soft
Clipping circuit gently limits the output of the system
to minimize audible distortion if the amplifier
is overdriven.
