NOTES ON INSTALLATION
Your NAD C720BEE 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. Make sure the
unit is switched off before making any connections.
The RCA sockets on your NAD C720BEE are colour coded for
convenience. Red and white are Right and Left audio respectively.
Use high quality leads and sockets for optimum performance and
reliability. Ensure that leads and sockets are not damaged in any way and
all sockets are firmly pushed home.
For best performance, use quality speaker leads of 16 gauge (1.5mm)
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 C720BEE, 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 USERSERVICEABLE
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.
QUICK START
1 Connect the speakers to the rear Speaker terminals and sources to
the relevant rear input sockets.
2 Plug in the AC power cord.
3 Press the VACATION button on the back of the C720BEE.
4 Press the POWER button to turn the NAD C720BEE on.
5 Press the required input selector.
REAR PANEL CONNECTIONS
ATTENTION!
Please make all connections to your C720BEE receiver with the unit
powered off or unplugged. (It is also advisable to power-down or unplug
all associated components while making or breaking any signal or AC
power connections.)
1-2 FM & AM ANTENNA:
The supplied wire "dipole" FM antenna will
connect to the FM connector using the supplied "balun" adapter. It
will usually work best when mounted on a vertical surface such as a
wall, with arms fully outstretched forming a horizontal "T"
perpendicular to the origin point of the signal. Experiment with
placement and orientation of to yield the clearest sound and lowest
background noise. In areas of difficult FM reception an external FM
antenna can yield dramatic gains in quality; consult your NAD audio
specialist or a professional antenna installer.
The AM loop antenna supplied with the C720BEE (or a suitable
replacement) is required for AM reception. Open the clip terminal
levers insert the wire and close, ensuring that the lever locks the wire
in place. Testing different positions for the antenna may improve
reception; vertical orientation will usually produce the best results.
Antenna proximity to large metal objects (appliances; radiators) may
impair reception, as will attempts to lengthen the wire to the loop.
NOTE:
An external AM antenna can improve long-distance reception
substantially; consult your NAD audio specialist or a professional
antenna installer. Do not connect anything other than a loop antenna
to the AM ANTENNA terminal. Do not remove the AM loop antenna.
3 SPEAKERS A & B
- Speaker terminals for speakers with an impedance
of 4 ohms or more. 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. Always use heavy duty (16
gauge; 1.5mm, or thicker) stranded wire to connect loudspeakers to
your NAD C720BEE. The high-current binding post terminals can be
used as a screw terminal for cables terminating in spade or pin
sockets or for cables with bare wire ends.
BARE WIRES AND PIN CONNECTORS
Bare wires and pin sockets 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. Ensure bare wire from the speaker cables does
not touch the back panel or another socket. Ensure that there is only
1/2" (1cm) of bare cable or pin and no loose strands of speakers wire.
POWERDRIVE
To meet the diverse requirements of high current drive and high
dynamic power, our patented PowerDrive amplifier circuit will build
further on our reputation for amazingly effective power. By adding a
second high-voltage rail to our well regulated high-current power
supply, we get an "overdrive" that can nearly double the continuous
power on a short term dynamic power basis. This is a further
development and refinement of our renowned Power Envelope
circuit, utilized by NAD in the 80's and 90's. PowerDrive differs from
Power Envelope in that it offers greater amplifier stability and low
impedance drive capability, resulting in less distortion when driving
real speakers with real program material.
4 SWITCHED AC OUTLET
- The AC power cord of another component
may be plugged into this accessory outlet. Components plugged into
this outlet will be switched On and Off by the VACATION SWITCH on
the rear panel.
NOTE:
The total power consumption of any components connected to the
AC outlets may not exceed 100 Watts.
5 AC line cord
- Plug the AC power cord into a live AC wall socket.
Make sure all connections have been made before connecting to
mains.
6. VACATION SWITCH ON/OFF
The VACATION switch is the master
on/off control for the amplifier. When the switch is in the ON state
the amplifier is in standby as shown by the amber LED above the
power switch on the front panel. If the amplifier will not be used for
an extended period of time, switch the VACATION switch to the OFF
position.
