Vistek V1635V-100 24-bit AES Audio
Variable Delay Module
1
Description
The V1635V is a broadcast quality 24-bit audio variable delay unit 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 screw
terminal connections, is required for all signal interconnections.
Depending on the build option chosen, input to the unit is either two stereo pairs of analog
audio inputs or two AES digital audio streams. Output from the unit is either two stereo pairs
of analog outputs or two AES digital audio streams. The V1635V is fully compatible with the
Vistek DART remote system, allowing status information to be read and control settings
invoked by a DART compatible rack controller.

supported.
The two AES inputs need not be the same sampling frequency as each other, or
the output, since the unit performs asynchronous sampling rate conversion.
4 x Analog differential quasi-balanced outputs with Z
Max input level: +28dBu = 0dBFS. Input sensitivity adjustable by on-card
switches from +14dBu = 0dBFS to +28dBu = 0dBFS in 1dB steps.

Sampling frequencies of 32kHz, 44.1kHz, 48kHz.
AES outputs A and B can reference-locked to an NTSC/PAL video source, a
separate AES reference source, or can be free-running to the internal crystal
oscillator.
AES channel status output to AES3-1992. Channel status present on the input is
passed to the output, amended appropriately for the setting in use.
