reasonably strong radio station, where it will stop.
Press the Down/Up button again for 1/2 second to
start searching again.
NOTE:
Automatic tuning is available on both FM and AM.
By briefly tapping the Down or Up buttons you can
engage manual tuning respectively down or up the
frequency band for precise tuning to a specific fre-
quency. 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 factory set at 10 kHz.
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.
[ 06 ] Tune/Preset button:
The Tune/Preset button toggles between the Preset
and Tune mode. When Preset mode is selected,
“PRESET” lights up in the display area.
Refer to the Tuner Up/Down button
[ 05 ] description
for more information.
[ 07 ] Display window:
The display area shows all vital information when
the unit is operational.
[ 08 ] Volume knob:
The Volume control adjusts the overall loudness of
the signals being fed to the preamplifier outputs.
Unlike conventional controls, the GTP-830’s volume
control doesn’t have a start or end position. Volume
can also be adjusted from the remote control using
the Master Volume Up or Down buttons
[ 29 ] . The
Volume control does not affect recordings made
using the Tape, Video 3 and Video 4 outputs but will
affect the signal going to the Preamp Outputs. The
volume level is indicated in the display panel when
it is being adjusted, and after three seconds the dis-
play defaults to its previous status. Volume setting
can range from -61dB to +18dB.
On the remote control, press the
Mute button
[ 27 ] to temporari-
ly switch off the sound to the
Preamp outputs and head-
phones. Mute mode is indicated
by “MUTING” flashing in red in the display area.
Press Mute again to restore sound. Mute does not
affect recordings made using the Tape, Video 3 and
Video 4 outputs but does affect the signal going to
the Preamp Outputs.
[ 09 ] Headphone Output and Video 5 inputs:
A 1/4” stereo jack socket is provided for headphone
listening and will work with conventional head-
phones of any impedance. The volume and tone
controls are operative for headphone listening.
Use a suitable adapter to connect headphones with
other types of connectors such as 3.5mm stereo
‘personal stereo’ jack plugs. Inserting a headphone
will automatically turn off the signals from the
Preamp Outputs, and set the listening mode to Stereo.
NOTE:
The sound from the ext 5.1input is not available on the
headphones socket.
REMEMBER:
Listening at high levels can damage your hearing.
The video five input is located on the front panel to
simplify connection of a camcorder or a video game
console. To select video five, push the correspon-
ding front panel button in the input selector section.
[ 10 ] Surround Backs button:
Pressing this button toggles the Surround Back
channels on and off. The Surround Back channels
work in conjunction with the Surround Rear chan-
nels to provide a more engaging and enveloping
listening experience. Due to the varying nature of
film soundtracks and music, you may prefer to acti-
vate or deactivate the Surround Backs. For example,
Dolby Digital 5.1 and DTS soundtracks benefit most
from the addition of Surround Back channels, since
they provide discrete rear channels. Pro Logic
soundtracks, on the other hand, provide a mono
surround track, which yields a less satisfying experi-
ence when using the Surround Backs.
The level of the Surround Back channels can be
adjusted in the same manner as the other channels,
either through the On-Screen-Display
(OSD) or with the Bal. or Test
functions from the remote con-
trol. Be sure to experiment to find
the balance that best suits your taste.
