The 2-U rack-mount unit features multiple inputs including two AES3 inputs, a
Toslink optical input, and an Ethernet port for RTP-streaming Dolby Digital audio.
The inputs are easily selected with dedicated front-panel buttons.
The front panel also incorporates a display screen, featuring high contrast and a wide
viewing angle. In addition to providing an intuitive interface for menu access and
setup, the display is easy to read and offers clear graphic status menus for all Dolby
Digital metadata settings and metering of output levels and dynamic range control.
The rear panel includes the main audio output connections for both digital AES3 and
analog +4 dBu balanced outputs. A linear timecode (LTC) output generates timecode
from a Dolby Digital bitstream, allowing DVD facilities to check A/V sync between
encoded Dolby Digital audio files and uncompressed video. Front- and rear-panel
serial interfaces and an Ethernet port enable remote control and software updates; a
remote control software application is included to configure and control the DP564
from a PC via Ethernet or serial connection. Remote control is also possible from an
optional dedicated hardware controller—either the Dolby Cat. No. 549 GPIO
Controller or another system using the general-purpose I/O connector (
GP I/O
).
