DP564 Multichannel Audio Decoder Operating Modes
6-3
6.1.3 Listening
The Listening section provides the ability to emulate different listening environments
at a single touch.
• Full uses all speaker outputs. The signals are routed to the speakers directly.
• 3 Stereo routes the Ls and Rs signals to Left and Right outputs, respectively.
• Phant (Phantom Center) mutes the Center output and splits the Center signal
equally between Left and Right.
6.1.4 Compression
The options in the Compression section are available only when decoding a
Dolby Digital signal. RF and Line apply dynamic range control profiles carried in the
Dolby Digital bitstream, in the same way consumer decoders do. Custom is a scalable
application of the Line profile.
The factory setting for Custom is 0 percent. At that setting, selecting Custom turns
dynamic range compression off. To access the display screen to adjust the percentage
setting for custom scaling, hold down Custom for two seconds.
Note: When downmixing, the DP564 automatically applies enough compression at
peak moments to prevent signal overload, regardless of whether a
compression mode is selected.
For more detailed information on compression modes, see Section A.3, Dynamic
Range Control.
6.2 Hardware Remote Control You can control the DP564 with a dedicated hardware remote control. When a GPI/O
control device is connected to the rear-panel GP I/O port, it is active, but not
exclusive—the front-panel controls also remain active.
To set up remote-control parameters, on the Unit Setup menu, select
I/O Control, then GPI/O Configuration.
If you are using the Cat. No. 549 GPIO Controller from Dolby Laboratories, connect
it and select Cat. No. 549 Config. If you have your own GPI/O control device,
connect that and select GPI/O Pin Config.
Note: Presets include all the DP564 settings, including the GPI/O configuration.
GPI/O settings should be assigned before saving a preset.
