3.10Additional Options Surround Data Format Lock

The GTP-880 will automatically set the surround format based on the signal it receives from the selected source. To avoid the slight delay occasionally encountered in the auto select process, you can choose to override the auto data format detection circuitry by following the procedure below.

To lock a specific surround mode:

1.Press the desired surround mode button (Dolby, DTS, or stereo) on the remote control repeatedly to cycle through the available processing options. Your selection will appear on the front panel display and OSD.

2.Press the same button for five (5) seconds to choose from among three data format options for digital audio sources. The following is shown on the front panel display and the OSD:

Auto is the default setting for this option, and means that when the unit detects the special code imbedded within certain data streams such as Dolby Digital or DTS it will set itself to properly decode that type of incoming signal.

3.Use the and buttons to select one of the data format options. You can select either Dolby D(igital), DTS, or PCM (for Pro Logic II), as the default format. If you do this, signals that are not in the selected format won’t be recognized. Therefore, we recommend that you leave the system in auto mode unless you wish to use the selected mode exclusively.

The data format menu will disappear automatically approximately 10 seconds after you make your selection.

Dynamic Range

Dynamic range is a special feature of Dolby Digital that compensates for difficult listening situations by compressing the dynamic range of the speaker output. An example would be when you are watching a movie with a soundtrack that contains very loud passages and you don’t want to disturb others in the house.

Both low-level boost and high-level cut compression inte- grated into night mode compensation is only available when the surround mode of the selected input source is set to Dolby Digital or Dolby Digital EX and downmixing is not enabled (i.e. if the source is a 3/2.1 AC-3 stream, the system must be configured to have at least a 5.0 speaker setup, or greater). When the system is downmixing a multichannel AC-3 stream and Night mode compression is enabled, the low-level signals may still be boosted, how- ever the high-level signals will not be compressed.

To enable/disable Night Mode compensation:

1.Press the d.range button on the remote control. The night mode selection appears on the front panel display and OSD under the currently selected input source.

2.Use the and buttons to change the night mode
