Dolby Laboratories DP524 - Manual (Page 21)

SECTION 4
INSTALLATION
4.1 Mounting
The DP524 is designed for 19 inch rack mounting, but may be mounted in any plane
and with any orientation. It occupies 1U (1 3/4") of space.
When mounting the unit, ensure that there is air flow around it, and that it is not
mounted directly above any equipment generating high amounts of heat. The unit
will operate within specifications up to a maximum ambient temperature of 50
°
C
(122
°
F). Note that the ambient temperature inside a poorly-ventilated rack may be
considerably higher than that in the room.
4.2 Audio Connections
4.2.1 S/PDIF Output - J102
Connect this output to the S/PDIF digital audio input of the equipment following
the DP524 using 75 ohm shielded cable.
Note To maintain better mechanical and electrical integrity, the rear panel connector on the DP524 is a
BNC female connector rather than the typical phono jack normally encountered in S/PDIF installations.
4.2.2 AES/EBU Output - J101
Alternatively, connect this output to the AES/EBU digital audio input of the
equipment following the DP524 using 110 ohm balanced and shielded cable.
Note The AES/EBU and S/PDIF outputs cannot be used simultaneously. If connections are made to both
outputs, neither will function properly.
4.2.3 Analog Outputs - J106/7
Alternatively, if using the Analog outputs, make connections at the DP524 analog
outputs J106 (Ch. A) and/or J107 (Ch. B) which are provided with industry-
standard XLR female connectors.
Note When operating in single channel audio coding modes, only audio from Channel A is used.
AES and IEC convention calls for XLR pin 2 to be “high/hot” and pin 3 to be
“low/cold”. In the interests of maintaining international standardization, we suggest
that the AES and IEC recommendations be followed.
