2.6.1Dimensions

The DP571 occupies one rack unit and measures 44 ⋅ 483 ⋅ 324 mm (1.75 ⋅ 19 ⋅

12.75 inches). Its net weight is approximately 2.7 kg (6 lb).

2.6.2Audio Connections

The digital audio inputs are provided on female BNC connectors. Input signals should be compliant with AES3-id-1995 (unbalanced, 75Ω , 1V peak-to-peak standard output). 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 75Ω video terminator. The PCM delay input is of the same specification, except that no termination is required as the PCM output is electrically isolated.

The main outputs and the PCM delay output are on female BNC connectors. The output is formatted in accordance with AES3-id-1995. The nominal output impedance for these connectors is 75Ω. The main outputs are electrically isolated and therefore no termination is required.

2.6.3Video Reference

A composite video signal should be connected to the video ref. BNC connector using a 75Ω shielded cable. There is a loop-through connection that will require a 75Ω termination if this facility is not being used.

2.6.4LTC Input

The DP571 accepts a SMPTE LTC signal. After decoding in the LTC receiver, the resulting time code information is passed to the DSP subsystem.
