Dolby Laboratories DP524 - Manual (Page 7)

SECTION 1
INTRODUCTION
1.1 Introduction
The Dolby Model DP524 is a digital audio decoder unit supporting both Dolby AC-
2 and Dolby AC-3 digital audio coding algorithms. The unit supports up to two
channels of audio. The data rates available are considerably lower than that required
to convey conventional PCM data (between 40k and 384k bits/sec) yet provide
exceedingly high audio quality.
The unit automatically configures itself for the appropriate data rate, sample rate
and algorithm type.
Both digital (AES/EBU and S/PDIF) and analog outputs are provided.
A full duplex serial control system has also been implemented which allows the user
to retrieve Status or Aux. data from the decoder. It is also possible for the user to
update the units software revision by means of a serial download capability.
The decoder provides front panel system status indicators as well as the ability to
respond to serial inquiries relating to system status.
A digitally generated test signal is provided for system alignment and
troubleshooting and can be activated from a rear panel switch or via the serial
control system.
Rear panel analog output level trimmers are provided.
This manual includes installation procedures, descriptions of Model DP524
operation, and interface specifications.
