FRONT PANEL CONTROLS
1 Power
- Press the POWER button to switch the unit from Stand-by to
the operating mode; The Stand-by indicator (Fig. 2; No. 2) will turn
from amber, to red, then to green. Press the POWER button to switch
the unit to the Stand-by mode: The Stand-by indicator will light up
amber. Upon selecting any input at the front panel or the ON button
of the remote, the C720BEE will choose the last selected as the active
input.
NOTE:
The remote control handset supplied with the C720BEE is of a
universal NAD type, designed to operate several NAD models. Some
buttons on this handset are inoperative, as the functions aren't
supported by the C720BEE.
2 Power/Standby/Protection LED
- Upon switching the power on, the
LED will light up red for a few seconds before the protection circuit is
deactivated. In cases of serious abuse of the amplifier, such as
overheating, excessively low loudspeaker impedance, short circuit
etc. the amplifier will engage its Protection circuitry, indicated by the
LED turning from green to red, and the sound being muted. In such
a case, turn the amplifier off, wait for it to cool down and/or check
the speaker connections, making sure the overall loudspeaker
impedance doesn't go below 4 ohms. Once the cause for the
protection circuitry to engage has been removed, press Power again
to resume normal operation.
3 BLEND
The Blend button toggles between engaging or disengaging
the Blend feature; when engaged, "BLEND" lights up in the VFD.
4 DISPLAY
When the AM/FM tuner is the selected input, sequentially
pressing DISPLAY shows the currently tuned station's RDS data,
toggling between the current station's Radio Text and Station Name
displays
5 MEMORY
Use to store tuned stations to the C720BEE's 40 preset-
memory locations.
6 FM MUTE/MODE
- In the normal Mute position, only the stations with
a strong signal can be listened to, and the noise between stations is
muted. Pressing the [FM Mute/Mode] button allows distant (and
potentially noisy) stations to be received.
7 PRESET
- Press either PRESET buttons to step up or down between
radio presets; 30 FM and 10 AM station presets are available. NOTE
that this function "wraps": Pressing the PRESET buttons will step
from Preset 30 to Preset 1, or vice versa. "Unused" presets are
skipped over. (NOTE that Presets must previously have been stored)
8 TUNE
- Press either TUNE button momentarily to step up or down
between FM or AM frequencies. Press and hold TUNE buttons for
more than 2 seconds to search up or down; the C720BEE's tuner will
stop at the next sufficiently strong signal it encounters. NOTE that this
function, too, "wraps," and will continue searching up or down from
one end of the AM or FM band to the other.
NOTE
that: TUNE button increments the FM band by 0.05 MHz steps
(twice the precision of most tuners). On the AM band, TUNE
increments the AM band by 10 kHz or 9 kHz steps. To change the
step amount, select AM and then hold in the FM MUTE/MODE and
AM keys simultaneously.
9 Infra-red remote control command receiver
- The infrared sensor,
located beside the VFD, receives commands from the remote control.
There must be a clear line-of-sight path from the remote control to
this window; if that path is obstructed, the remote control may not
work.
NOTE:
Direct sunlight or very bright ambient lighting may affect the
operating range and angle for the remote control handset.
10 DISPLAY PANEL
- The Display Panel shows information about the
C720BEE's operating modes and information about the station
currently selected, Audio Mute, Blend, FM Mute, Stereo, Centre Tune,
etc. are all indicated in this window. The display also has an eight
character alphanumeric section, which will display the active input,
station name, Radio Text or frequency.
11 RECORD OUT/ZONE 2 SELECTOR
- This selector switch doubles as
both a record source selector and a second zone source. Control is
also achieved by use of the ZR-3 zone remote control.
12 VOLUME
- The VOLUME control adjusts the overall loudness of the
signals being fed to the loudspeakers. It is motor driven and can be
adjusted from the remote control handset. The VOLUME control does
not affect recordings made using the Tape outputs but will affect the
signal going to the Pre-amp output (Pre Out).
On the remote control handset, press the MUTE button to
temporarily switch off the sound to the speakers and headphones.
Mute mode is indicated by the MUTE icon in the VFD. Press the MUTE
button again to restore sound. Mute does not affect recordings made
using the Tape output but will affect the signal going to the Pre-amp
output (Pre Out).
13 BALANCE
- The BALANCE control adjusts the relative levels of the left
and right speakers. The 12 o'clock position provides equal level to the
left and right channels. A detent indicates this position. Rotating the
control clockwise moves the balance towards the right. Rotating the
control anti-clockwise moves the balance to the left. The BALANCE
control does not affect recordings made using the Tape output but
will affect the signal going to the Pre-amp output (Pre Out).
14 TONE DEFEAT
- The TONE DEFEAT switch by-passes the tone control
section of the NAD C720BEE. If the Tone Controls are not normally
used and left in the 12 o'clock position, then it is advisable to switch
out the Tone Control section altogether by using this switch. In the
'out' position, the Tone Control circuits are active; pushing the TONE
DEFEAT switch 'in' bypasses the Tone Control section.
15 Tone controls
- The NAD C720BEE is fitted with BASS and TREBLE
tone controls to adjust the tonal balance of your system. The 12
o'clock position is 'flat' with no boost or cut, and an indent indicates
this position. Rotate the control clockwise to increase the amount of
Bass or Treble. Rotate the control anti-clockwise to decrease the
amount of Bass or Treble. The Tone controls do not affect recordings
made using the Tape outputs but will affect the signal going to the
Pre-amp output (Pre Out).
