Page 24: Video Reference
Dolby Installation Guidelines AES3-id signals are very similar to analog composite video, although dedicated AES3 distribution equipment should be used. If the loop-through BNC connectors are not being used to feed additional equipment, terminate them with a standard 75 video terminator. The PCM delay input is of the same specification as the main input, except that no termination is required as the PCM output is electrically isolated. -

Page 29: Chapter 3 Installation Issues
Venting The Dolby professional audio products are designed to operate within a temperature range of 5° to 45° C. They use natural convection cooling and therefore should not be mounted directly above any heat-generating equipment. DP-series products, with the exception of the DP570, have vent holes in the top and bottom panels, along the left or right edge, depending on the unit (left side for the DP562, DP571, and DP572;... -
Page 30: Dolby Digital Coding And Decoding Delays
Dolby Installation Guidelines 3.2.2 Dolby Digital The amount of delay added by the Dolby Digital encode/decode process varies depending upon the sample rate being used. The table below shows the minimum delay values for encoding. The DP569 allows for the encoding delay to be increased to any value between the minimum value and 450 ms. -
Page 31: Chapter 4 Hot Standby And Alarms
Many Dolby products allow simple implementation for hot standby applications. Hot standby units and redundancy should be considered at a system level. Systems that utilize hot standby features allow automatic routing of the required signals from a unit that develops a fault, to a spare unit in the system. The Dolby products can easily be integrated into other redundant systems, such as the “n+1”... -
Page 32: Dp570
Dolby Installation Guidelines Figure 4-1 Hot Standby Operation of the DP569 For further security, pins 1 and 9 (ground) of the GPI/O ports can be used to control a unit fault alert. If pin 1 goes “low,” then a power supply or hardware fault has occurred. These can be used on both the encoders so that a faulty standby encoder can be identified before it is required. -

Page 40: Serial Control
Dolby Installation Guidelines For further information about metadata, see user manuals or the Dolby Digital Professional Encoding Manual. The DP569, DP570, and DP571 have metadata inputs; the DP570 and DP572 have metadata outputs. Connecting a metadata input to a metadata output requires a 9-pin male to male cable with direct connections between the pins.
