Getting Started
Installing the DP570
2.3.1 Venting
Dolby
®
professional audio products are designed to operate within a temperature range of
5°C to 45°C. They use natural convection cooling and therefore should not be mounted
directly above any heat‐generating equipment. The DP570 has vent holes in the front and
back of the unit, and can be placed directly above or below other rack‐mounted gear.
2.3.2 Making Input Connections
Connect the mandatory multichannel PCM signals to the digital jacks. Use care to attach
the input cables to the proper connector to avoid inadvertently moving channels.
For a discussion of the connector types used on the DP570, see
You may also connect a Dolby Surround encoded stereo PCM mix to either of the
Lt/Rt
Inputs
jacks. Use the second jack either to pass the signal to another device or to terminate
the connection with a 75Ω impedance.
2.3.3 Making Output Connections
There are two sets of digital audio outputs on the rear panel. One is the output from the
router and the other is from the emulator.
For a discussion of the connector types used on the DP570, see
Router Output
Use the
Router Outputs
for the main digital signal output regardless of whether you are
reassigning signals to different channels. For information on how to reassign input signals
to different channels, see
Channel Mapping and Input Routing
Emulator Output
These outputs are affected by metadata changes you make in the DP570 and should only
be used to send a signal to the monitoring system. Connect them to your own D/A
converter if you are monitoring without using the Cat. No. 548 Analog Option Card.
2.3.4 Making the V Ref Connection
Connect the V Ref signal to either of the two jacks on the rear panel. Use the second jack
either to pass the signal to the next device in the chain, or to terminate it with a 75Ω
impedance on the last device in the signal chain.
Note: The DP570 will not operate without a valid sample clock signal present at the
channel 1/2 input connection.
