GTP-830 DIGITAL PROCESSING TUNER/PREAMPLIFIER

[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.

[31] Play button:

In CD mode, it is preprogrammed for play with an ADCOM CD player.

[32] Pause button:

In CD mode, it is preprogrammed to pause an ADCOM CD player.

[33] Stop button:

In CD mode, it is preprogrammed to stop an ADCOM CD player.

[34] Arrow buttons:

The arrow buttons allow navigation throughout the GTP-830 OSD (On Screen Display) menus (as well as the menus of other devices, once the commands are learned). Please refer to section 3.1 for further explanations on the OSD.

Left arrow: In main mode, this is preprogrammed to step through the various choices you might wish to select while a menu item is highlighted.

In CD mode, it is preprogrammed for audible reverse scan with an ADCOM CD player.

Up arrow/Setup: In main mode, this is prepro- grammed to enter the OSD menu system, as well as scroll up to the next choice on a menu screen.
