Adcom GTP-830 - Manual (Page 22)

[ 27 ] Mute button:
In all modes, this button is preprogrammed to mute
outputs of device. Mute does not affect recordings
made using the Tape outputs but will affect the
signal going to the Preamp Outputs. When the unit
is in mute mode, any adjustment of the Volume
Control on the front panel
[ 08 ] will release the mut-
ing, i.e. the original volume level will be resumed.
[ 28 ] d.range (dynamic range) button:
In main mode, this button is preprogrammed to
adjust dynamic range of Dolby Digital encoded
sources.
The d. range button, which can be used only in
combination with a Dolby Digital source, incremen-
tally reduces the audio track’s dynamic range in
four steps (100%, 75%, 50% and 25%) to allow for
comfortable listening under a variety of conditions.
The normal or default position is 100%. To adjust
the dynamic range, each consecutive press of the
d. range button will reduce the value in 25%
increments, as shown in the alpha-numeric
display section.
Although we usually prefer to reproduce a source’s
full dynamic range (the difference between very
loud and very soft sounds), it may occasionally be
desirable to reduce the dynamic range. For exam-
ple, when playing a movie late at night, loud explo-
sions might wake sleeping family members. Simply
turning the volume control down would probably
make a whisper in the next scene inaudible. The
d. range button solves this dilemma by progressive-
ly lowering the volume of loud peaks while
increasing the level of softer sounds.
[ 29 ] Volume Up/Down buttons:
In all modes, these buttons change the master
volume setting of the GTP-830. In all modes except
main, they can be reprogrammed with new com-
mands. The Volume control does not affect record-
ings made using the Tape and Video, or Tape, Video
3 and Video 4 outputs but will affect the signal
going to the Preamp output.
[ 30 ] Mode button:
In main mode, this is preprogrammed to cycle
through the surround modes of the GTP-830.
Pressing repeatedly will cycle through Pro Logic,
Hall, and Stereo, when available. Refer to the
Surround Mode description
[ 12 ] for more
information.
