Fm Antenna; Soft Clipping; Speakers A + Speakers B; Nad Link In, Out - NAD C740 Owner's Manual

10. FM ANTENNA

A ribbon wire FM antenna is included and should be connected to
the FM connector at the rear of the unit
(The 120V versions (North America) should use 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 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 its specified power output, a
hard, distorted sound can be heard on very loud sounds. This is
caused by the amplifier cutting 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 minimise
audible distortion if the amplifier is overdriven.
If your listening involves moderate power levels you may leave the
Soft Clipping switch to Off. If you are likely to play at high levels,
that could stretch the amplifier's power capability, then switch Soft
Clip On.
"SOFT CLIPPING" lights up in the display area when the receiver
is in Soft Clip mode.

12. SPEAKERS A + SPEAKERS B

The NAD C740 is equipped with two sets of speaker connectors.
Use the Speakers A connectors for the 'main' speakers and use the
Speakers B connectors for a second pair, for example, extension
speakers located in another room.
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; 1.5mm, or thicker) stranded
wire to connect loudspeakers to your NAD C740.
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. (see fig 3)
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.
NOTE: Make sure the speaker impedance is 4 ohms or more
when connecting only one pair of speakers; make sure the
speaker impedance for all speakers is over 8 ohms when
connecting two sets of speakers.

13. NAD LINK IN, OUT

The NAD-Link connector is used to pass commands from other
units fitted with NAD-Link connectors. This allows centralised
control of a complete system, and also allows some of the basic
functions of other NAD components (such as a CD player or
cassette-deck) also equipped with NAD-Link to be controlled with
the receiver's remote control. To function with such other units,
connect the C740's NAD-Link Out to the NAD-Link In on the other
unit. NAD-Link connectors can be daisy-chained, IN to OUT, so
that a whole system can be controlled from the remote control
facilities of one unit.

14. 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.
FRONT PANEL CONTROLS
1. POWER ON/OFF
Press the POWER button to switch the receiver to its 'Stand-by'
mode. The Stand-by indicator (No. 4) over the power button will
light up. On the front panel, press any of the input selector buttons
to switch to receiver on. From the remote control, press the green
Stand-by button (located just over the Speakers A and B buttons)
to switch the unit on. The display will light up indicating which
input was selected, the Stand-by indicator will extinguish.
Pressing the POWER switch again will turn the unit OFF
completely. The NAD C740 receiver uses a memory back-up
system to store preset station information for the tuner section.
This information is retained for several weeks, even the unit is
switched off completely or unplugged.

REMOTE CONTROL

STAND-BY button (green):
Press this button to switch the unit from operating to the Stand-by
mode and vice versa: Press this button again to switch to unit on
from Stand-by; the last selected source will be indicated in the
display.
NOTE: Stand-by mode is indicated by the Stand-by indicator (No. 4)
just over the green POWER button on the front panel (No. 1)
In Stand-by mode the C740 uses very little power. However, it is
recommended that you switch the unit totally off if it is not going to be
used for more than a couple of days. Switch off completely by pressing
the POWER button on the front panel (No. 1), all lights will extinguish.
2 + 3. SPEAKERS A; SPEAKERS B
The A and B buttons engage or disengage the speakers connected
to respectively the Speakers A and Speakers B terminals on the
rear panel.
Press A to switch the speakers connected to the speaker A
terminals On or Off.
Press B to switch the speakers connected to the speaker A
terminals On or Off.
The status of speakers A and B On or Off is indicated in the upper-
left corner of the display area. If Speakers A and B are both engaged
(shown by "SPEAKERS A B" in the display area), the amplifier's
output power is fed to both sets of speakers in parallel. If speakers
A and B both are disengaged, both sets of speakers are silenced.
You can use this setting mode to listen to headphones (No. 5).
NOTE: Always turn the volume down when engaging or
disengaging either Speaker A or Speaker B.
