D22 - On-Line Broadcast Delay
High resolution Delay for broadcast master control and linking. Delay-time may be adjusted while signal is being passed, thanks to a low artifact processing technique. The delay is easily adjustable from the front panel using dedicated Nudge keys, Encoder and Tap function. Increments can be set in ms, fields or frames, and the unit delays linear audio as well as Dolby E or AC3 streams. Remote control of by-pass and delay time is available through GPI or RS485 inputs. Balanced and unbalanced AES/EBU I/O is standard, and outputs are always active. Sample rate conversion can be invoked when using digital inputs.
Analog I/O is standard, and outputs are always active. The 24 bit converters are scaled in the analog domain, with scaling under preset control, to minimize noise and maximize headroom under all operating conditions.
