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.
11. 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 it
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 over-
driven.
If your listening involves moderate power levels you
may leave the Soft Clipping switch off. If you are like-
ly to play at high levels that exceed the amplifier’s
power capability, then switch Soft Clipping on.
12. VIDEO 1
Connection for the Line (Composite) video signal
input for VIDEO 1. Using a phono lead, connect the
‘Video Out’ of the VCR, TV, Laser Disc or
satellite/cable unit. VIDEO 1 can be used for video
playback only. Use VIDEO 2 if you want to connect a
VCR for recording and playback through the AV 713.
13. VIDEO 2
Connection for the Line (Composite) video signal
input for VIDEO 2. Using a phono lead, connect the
‘Video Out’ of the VCR to VIDEO 2 IN for playback.
Connect VIDEO 2 OUT to the ‘Video In’ of the VCR to
copy video signals from VIDEO 1.
14. MONITOR VIDEO OUTPUT
Composite (line) video output for connecting a TV
or Video Monitor to view video sources connected to
VIDEO 1 or VIDEO 2. Using a phono lead, connect
the ‘Video Line In’ on the TV or monitor to the MONI-
TOR VIDEO OUTPUT. This output can also be used
as an additional recording output if required. Video
monitoring must then be done via the output of the
video recorder.
15. FRONT SPEAKERS A
These are the amplifier outputs for the front speak-
ers normally located in the main listening room.
These speaker outputs are switched on and off by
using the SPEAKER A button on the front panel.
Connect the right speaker to the terminals market
‘R +’ and ‘R-’ ensuring that the ‘R+’ is connected to
the ‘+’ terminal on your loudspeaker and the ‘R-’ is
connected to the loudspeaker’s ‘-’ terminal. Connect
the terminals marked ‘L+’ and ‘L-’ to the left speaker
in the same way.
Always use heavy duty (16 gauge or thicker)
stranded wire to connect loudspeakers to your AV
713.
The high current binding post terminals can be
used as a socket for speaker cables ending with 4mm
plugs or as a screw terminal for cables terminating in
spade or pin connectors or for cables with bare wire
ends.
4mm (BANANA) CONNECTORS. These should be
soldered or securely screwed to the speaker cables
before inserting into the sockets. The terminals are
3/4” (19mm) apart so they will accept standard dual-
banana plugs.
SPADE CONNECTORS. These should be slotted
under the terminal’s screw bushing, which is then
tightened down. Ensure the connector is tightly
secured and there is no danger of bare metal from
spade connectors touching the back panel or another
connector, as this may cause damage.
Bare wires and pin connects should be inserted
into the hole in the shaft of the terminal. Unscrew the
speaker terminal’s plastic bushing until the hole in the
screw shaft is revealed. Insert the pin or bare cable
end into the hole and secure the cable by tightening
down the terminal’s bushing (see fig 4).
To avoid any danger of bare metal from the speak-
er cables touching the back panel or another connec-
tor, ensure that there is only 1/2” (1.27 cm) of bare
cable or pin and no loose strands of speaker wire
CAUTION: Any speaker used on the AV 713
should have a minimum impedance of 4 ohms.
16. FRONT SPEAKERS B
These are the amplifier outputs for the front speak-
ers normally located in the secondary listening area
(such as a dining room or kitchen).
These speaker outputs are switched on and off by
using the SPEAKER B button on the front panel.
Connect the right speaker to the terminals marked
‘R +’ and ‘R-’ ensuring that the ‘R+’ is connected to
the ‘+’ terminal on your loudspeaker and the ‘R-’ is
connected to the loudspeaker’s ‘-’ terminal. Connect
the terminals marked ‘L+’ and ‘L-’ to the left speaker
in the same way.
The high current binding post terminals can either
be used as a socket for speaker cables ending with
4mm plugs or as a screw terminal for cables terminat-
ing in spade or pin connectors or with bare wire.
17. CENTER SPEAKER
This connects the center loudspeaker that is used
when the AV 713 is operated in Dolby Pro-Logic
mode. Connect the ‘’ to the ‘+’ terminal on
your center loudspeaker and the ‘Center -’ to the
loudspeaker’s ‘-’ terminal.
Strip 8mm of insulation from the end of the speaker
cable and twist the bare wires so that there are no
loose strands. Open the clip terminal lever and insert
the wire. Closing the lever will lock the wire in place.
These speakers operate in conjunction with Front
Speakers A and are switched on and off by using the
SPEAKER A button on the front panel.
