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 as the main input, except that no termination is required as the PCM output is electrically isolated.
The digital outputs and the PCM delay output are on female BNC connectors. The outputs are formatted in accordance with AES3-id-1995. The nominal output impedance for these connectors is 75Ω. The secondary digital outputs are electrically isolated and therefore no termination is required.
The headphone output is a ¼-inch standard audio headphone jack with +11.5 dBu maximum output into 600Ω nominal.
2.7.3Video 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.
2.7.4LTC Output
After de-multiplexing time-code information from the Dolby E stream, the DP572 provides a standard SMPTE LTC output.
2.7.5Serial I/O (Remote)
Future versions of the DP572 will allow remote control via the front-panel (RS-232) or rear-panel (RS-485) ports. See Section 6.4 for further information. The serial I/O connections can also used for software upgrades.
2.7.6General Purpose Input/Output (Status Port)
The input and output signals are 0–5 V TTL.
