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.

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.
