Installation Issues

3.1Venting

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; right for the DP563 and DP569). The vent holes should not be covered, although units can vent through one another if necessary. In this event, be sure that the venting panels are on the same side on each unit. The number of units that can be vented in this way will depend on the conditions of the room in which they will be installed.

The DP570 features vent holes in the front and back of the unit, and can be placed directly above or below other rack-mount gear.

3.2Timing and Delays

Encoding and decoding adds delay to the audio data. In audio-only situations this may be of little consequence, but where the audio has associated video material, care should be taken to ensure that these delays are accounted for. This can be done by adding the equivalent delay to the video stream, by compensating for the delay at the video encoding stage, or by adding an offset between the time code of the source tapes. The amount of the delay varies depending on the technology being used.

3.2.1Dolby Surround

The delay associated with the Dolby Surround encode/decode process is effectively zero. The DP563 does allow for the encoding delay to be varied between minimum (<1 ms) and 100 ms. The DP562 has little latency (approx 3msec@48kHz) when in Disabled or Reference bitstream detect modes, although this increases if bass redirection is used. When in Silent Switch mode, the decoding latency will be the same as for Dolby Digital. Silent Switch mode includes a crossfade when the input switches between different formats.
