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.
