IDENTIFICATION OF CONTROLS
FRONT PANEL
1 STANDBY BUTTON
•
Press this button to switch ON the C 427 from standby mode. The
Standby LED indicator will turn from amber to blue and illuminate
the VFD.
•
Pressing the STANDBY button again turns the unit back to standby
mode.
2 STANDBY LED
•
This indicator will light up amber when the C 427 is at standby
mode.
•
When the C 427 is powered up from standby mode, this indicator
will illuminate blue.
NOTE
In order to turn ON the C 427 from standby mode or back to standby
mode, the rear panel POWER switch must be in the ON position.
3 AM
•
Select AM band.
4 FM
•
Select FM band.
5 FM MUTE
•
The front panel [FM MUTE] button is a dual-purpose control. In the
normal position, “Stereo” and “FM Mute” are shown in the VFD; only
the stations with a strong signal can be listened to, and the noise
between stations is muted.
•
Pressing the [FM MUTE] button again (“Stereo” and “FM Mute” are
extinguished; “Tuned” is displayed) allows distant and potentially
noisy stations to be received. Noise is reduced if the FM station
signal level is less than the FM Stereo threshold (since mono FM is
inherently less noise-prone) though at the sacrifice of the stereo
effect.
•
The “FM MUTE” status can be stored for individual presets.
6 DIMMER
•
Toggle the [DIMMER] button to reduce or restore VFD brightness.
7 REMOTE SENSOR
•
Point the TNR 3 remote control at the remote sensor and press the
buttons. Do not expose the remote sensor of the C 427 to a strong
light source such as direct sunlight or illumination. If you do so, you
may not be able to operate C 427 with the remote control.
Distance:
About 23 ft (7 m) from the front of the remote sensor
Angle:
About 30° in each direction of the front of the remote sensor
8 VACUUM FLUORESCENT DISPLAY (VFD)
•
Provide visual information on the settings, conditions, status and
other information relevant to the currently tuned station.
9 BLEND
•
The NAD BLEND feature will allow you to reduce the amount of
noise and hiss but still retain some level of stereo separation, instead
of mono.
•
The [BLEND] button toggles between engaging and disengaging
the BLEND feature. When activated, “Blend On” is shown in the VFD;
“Blend Off” when not activated.
•
The “BLEND” status can be stored for individual presets.
•
In combination with [MEMORY] button, [BLEND] button is also
used in deleting stored presets. Refer also to the item about
DELETE A PRESET at the LISTENING TO AM/FM RADIO section of the
OPERATION page.
10 MEMORY
•
Press this button to store tuned AM or FM stations to the C 427’s
40 preset-memory locations. One can store a mix of any AM or FM
stations to the 40 available presets.
•
In combination with [BLEND] button, [MEMORY] button is also
used in deleting stored presets. Refer also to the item about
DELETE A PRESET at the LISTENING TO AM/FM RADIO section of the
OPERATION page.
11 PRESET/TUNE/SCROLL CONTROL KNOB
•
Toggle to switch between “Presets” and “Tune” mode. “Tune” or
“Presets” will be displayed in the second line of the VFD depending
upon the mode selected.
Preset mode:
Rotate the PRESET/TUNE/SCROLL control knob to the
left to scroll to a lower Preset number; rotate the PRESET/TUNE/SCROLL
control knob to the right to scroll to a higher Preset number. This is a
“wrap-around” function – upon reaching the last stored Preset number,
preset search will continue on with the first stored Preset number and
vice-versa. Unused preset numbers are skipped over.
Tune mode:
Rotate the PRESET/TUNE/SCROLL control knob for precise
tuning to a specific frequency. With each brief rotation, the tuner will
take 0.05 MHz steps at FM band and 10 kHz (120V version) or 9 kHz
(230V version) at AM band. When tuned accurately to a station, “Tuned”
is displayed in the VFD.
