V1630 AES-EBU DISTRIBUTION AMPLIFIER
1. DESCRIPTION
The V1630 is a broadcast quality AES-EBU digital audio distribution amplifier which forms part of the
Vistek V1600 range of interface products. It is a 3U high card which is fitted into either a V1601 or
V1603 rack, from which it receives its power. A passive rear module with either BNC or screw terminal
connections, is required for all signal interconnections.
The unit accepts two AES audio data streams of 32kHz, 44.1kHz, 48kHz or 96kHz and distributes
reclocked and regenerated AES data streams to 4 AES outputs per channel.
one of the two AES inputs are distributed to 8 AES outputs is also available as a panel control option.
The V1630 can accomodate a piggyback expander card which expans both output groups from 4 to 8,
providing for a maximum of 16 outputs. Consult Vistek sales for further details.
Two families of passive rear panel module are available:
· AES inputs and outputs to AES3-1992 (110W balanced) with screw terminals. This rear panel
provides for a 2:4 or 1:8 configuration.
· AES inputs and outputs to AES3id-1995 (75W single ended) with BNC connectors. This rear panel
provides for a (!:4 + 1:3) or 1:7 configuration, since only 9 BNC connectors can be accomodated on
the rear panel.
The V1630 has a passive equaliser which is jumper selectable on each AES input and operation is
guaranteed over cable lengths of up to 250 metres (at
up to 1000 metres may be accomodated, but this is not guaranteed .
· Input cable length 0 - 100m:
· Input cable length 100m+:
Input impedance may be set to either 110/75 W or Hi-Z to facilitate daisy-chaining V1630 inputs within a
V1600 rack.
The sampling rate of each channel is displayed by means of front panel LEDs and an ERROR LED is
provided to indicate channel errors/no input. Front panel switches allow the card operating mode to be
set and LEDs provide visual indication of the mode. The V1630 is compatible with the Vistek DART
remote system, allowing card ID, status and mode to be read, and card mode to be written by a DART
compatible rack controller.
Note:
This manual applies to V1630 Assy 130-1210 Issue B, which have different
functionality and pinout connections to previous issues.
