8. PRESET/TUNE
The Preset/Tune button toggles between two different modes:
a) Preset mode: In this mode you can use the Tune/Preset
or
buttons (No. 9) to select a Preset. When Preset Mode
is selected “PRESET” will scroll once through the display and
the PRESET indicator lights up in the display.
b) Tune mode: By pressing the Preset/Tune button (No. 9)
or
you can engage automatic or manual tuning
respectively down or up the frequency band. When Tune mode
is selected, “TUNE” will scroll through the display once.
9. PRESET/TUNE
AND
The function of these buttons depends on the tuning mode
selected with the Preset/Tune button (No. 8). The Preset/Tune
button toggles between the two operation modes:
a) Preset mode (indicated in the display area): Press the
(down) button to scroll to a lower number Preset; press the
(up) button to scroll to a higher Preset number. This is a
“wrap-around” function, so that going from the highest
number Preset, the tuner will go to the lowest Preset number
or vice-versa when tuning either up or down.
b) Tune mode: Press the
(down) or
(up) button for
more than 1 second to engage automatic tuning respectively up
or down the frequency band. The tuner will search
automatically for the first reasonably strong radio station,
where it will stop. Press the Down/Up button again for 1
second to start searching again.
By briefly tapping the
(down) or
(up) buttons you can
engage manual tuning respectively up or down the frequency band
for precise tuning to a specific frequency. With each successive tap
of the keys, the tuner will take 0.05 MHz steps on FM so you can
accurately tune into the desired frequency. For AM the tuning steps
are set at 10 kHz (120V version) or 9 kHz (230V version).
This tuning mode can also be useful when trying to receive a radio
station, which is too weak for the auto search mode. When tuned
accurately to a station, “TUNED” will light up in the display. The
muting circuit, however may suppress very weak radio station
signals. If such a very weak station is in stereo it will have a high
level of background hiss. Switching to Mono Mode and
disengaging the muting circuit by depressing the FM MUTE/MODE
button (No. 5) will allow the station to be heard and will cancel
most or all of this background noise.
NOTES:
Automatic tuning is available on both FM and AM.
Even if the C730 is in Tune Mode, the remote control’s Preset Up
and Down buttons will only change presets.
The Preset/Tune
and
buttons are also used in
conjunction with the Memory (No. 4) and Display (No. 7) buttons
to add and memorise user defined names to Presets. Refer to the
separate chapter “Storing, Recalling and Labelling Presets” for
more information.
10. DISPLAY AREA
The display area gives all vital information on the status of the
receiver. Displayed are:
• Which input is selected
• Volume MUTE On
• Tape Monitor engaged
• Tone Defeat On
• Band and frequency of current station, RDS PS (station name),
or RDS Radio Text. The latter two only if RDS is available; select
using the Display button (No. 7).
• If an FM Stereo broadcast is received.
• If the FM station also broadcasts RDS.
• If “Memory” has been engaged
• Preset number if the current station is stored in the tuner’s
memory bank.
• If Blend and FM Mute/Mode are switched On.
• Radio Signal Strength. The bars just below “ANTENNA” indicate
the radio station’s signal strength. The more bars are lit, the
stronger the station.
NOTE:
The infrared sensor, which receives commands from a
remote control (not supplied), is located on the left side of the
display window. 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.
11. 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 “MUTE” flashing in red in the display
area. Press MUTE again to restore sound. Mute does not affect
recordings made using the Tape outputs but will affect the signal
going to the Pre-amp output (Pre Out).
12. HEADPHONE SOCKET
A 1/4” stereo jack socket is supplied for headphone listening and
will work with conventional headphones of any impedance.
Inserting a headphone jack into this socket automatically switches
off the loudspeakers. The volume, tone and balance controls are
operative for headphone listening. Use a suitable adapter to
connect headphones with other types of sockets, such as 3.5mm
stereo “personal stereo” jack plugs.

REMOTE CONTROL
STANDBY/ON button (No.1)
When the receiver is switched On, pressing the green On/Off
button on the remote handset will put the receiver into Standby
mode and the Power indicator will turn amber. The amber Power
indicator shows that power is being supplied, but the system is
currently in the Standby Mode. Press again to switch the receiver
On from Stand-by mode.
ON and OFF buttons (No.2)
Besides the On/Off toggle function of the green button (No. 1), the
NAD C730 remote also has a separate On and Off button. This can
be particularly useful to keep components within a system “in-
sync”: This way all components will switch to stand-by when Off is
pressed or switch to operating mode when On is pressed, instead
of some components switching On when the receiver is switched
to Stand-by. (Note that the other components have to be capable
of responding to the separate On and Off commands as well).
Press the ON 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 green to indicate the receiver is ready for use.
Press the OFF button to switch the unit to the Stand-by mode: The
Stand-by indicator will light up amber.
NOTE:
In Stand-by mode the C730 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. STAND-BY INDICATOR
This indicator lights up green during normal operation. In Stand-
by mode the indicator will light up amber. Refer to section 1 in
this chapter for more information. The indicator will blink when
the receiver receives a remote control command from the
supplied handset.
If the receiver goes into “protection” mode the Led will flash
continuously at a rate of two flashes per second. This can occur if
there is a short circuit in the speaker wiring. Switch the unit off
totally using the Power button on the front panel (No 1) and
check all the cables and connections both at the receiver side and
at the loudspeakers side. Once all the connections are restored
correctly, switch the Power button (No 1) on, with the volume
initially set low and then resume normal operation. If the problem
persists, switch of the power completely and consult your dealer.
3. BLEND
Weak or remote stereo radio stations are sometimes received with
noise and hiss as the antenna signal is too weak. By switching the
tuner to mono will reduce the amount of noise and hiss but at the
expense of any stereo information. The NAD Blend feature will
allow you to reduce the amount noise and hiss but still retain
some level of stereo separation, instead of mono. The Blend
button toggles between engaging or disengaging the Blend feature;
when engaged, “BLEND” lights up in the display.
NOTE:
The “Blend” status can be stored for individual presets.
Refer to the separate chapter “Storing, Recalling and Labelling
Presets” for more information.
4. MEMORY
The Memory is used to store stations into the Preset Memory bank
and to store user defined names for non-RDS Preset stations. When
Memory is pressed during normal operation, the Preset number
and the red “MEMORY” indicator will flash in the Display Panel. If
no other buttons are pressed within 12 seconds, the receiver will
revert to its previous state. Refer to the separate chapter “Storing,
Recalling and Labelling Presets” for more information.
5. FM MUTE/MODE
This button combines two functions; it switches the receiver’s
tuner section from Stereo to Mono and disengages the muting
circuitry at the same time. The muting circuit will mute the tuner
in between radio stations when searching or tuning. This way the
tuning noise is avoided.
The muting circuit however may suppress very weak radio station
signals. If a weak station is in stereo it will have a high level of
background hiss. Switching to Mono Mode and disengaging the
muting circuit by depressing the FM MUTE/MODE button will
allow the station to be heard and will cancel most or all of this
background noise.
In normal operation the mute circuit is engaged, the display
indicates “FM MUTE”. Press the FM Mute/Mode button to
disengage the muting circuit and switch from stereo to mono
reception. “FM MUTE” in the display will extinguish. Press the FM
Mute/Mode switch again to return to Auto Stereo FM operation.
NOTE:
The “FM Mute/Mode” status can be stored for individual
presets. Refer to the separate chapter “Storing, Recalling and
Labelling Presets” for more information.
6. AM/FM
The AM/FM button switches the tuner from the AM band to the FM
band and vice-versa. The Display Panel shows the frequency of the
tuned station and which band is selected. The FM tuning is in 0.05
MHz increments, AM tuning is in 9 kHz or 10 kHz increments,
depending on the version.
7. DISPLAY
With stations carrying RDS information, The Display button scrolls
between three different display modes, each successive push of
the button engages the next one of the three modes:
a) In the default mode, the station’s RDS name is displayed,
Program Service (PS; normally the station’s calling letters, BBC
R3, for instance).
b) From the default mode, press the button once to view Radio Text
(RT). This can be additional information such as the presenter’s
or program’s name; what song is playing, etc. This text scrolls
continuously over the 8 alphanumeric display segments.
c) Press the button from the display RT mode to display the station
frequency. Press again to return to the default mode (a).
When tuned to a non-RDS station
The Display button toggles the display to show either the station
frequency or user entered station name. If no user name was
entered the display will indicate “NO RDS”.
The Display button is also used to label non-RDS stations with a
name. Refer to the separate chapter “Storing, Recalling and
Labelling Presets” for more information.
