Rane AVA 22D User Manual

DATA SHEET

General Description

The Rane AVA 22d is a fully balanced two Input, two

Output Audio / Video Alignment Delay providing a range of

0.0 to 9.5 NTSC or PAL/SECAM frames on each Output. 24­bit audio converters provide excellent sound quality.

Each Output has two nonvolatile Memories (no batteries
required), A and B, for easy access to previously stored Delay
values. Remote Recall screw terminals on the rear accept
external configuration switches, permitting independent
remote recall of the Memories.

The AVA 22d features XLR Inputs and Outputs, and is
CE certified for emissions. Housed in a single rack space, the
unit can operate as two independent channels (dual mono), or
as a stereo pair (edit both channels simultaneously using Link
Mode).

A recessed rear panel switch is available for locking out
front panel controls. In this mode, all of the front panel
pushbuttons are disabled with the exception of the Recall
buttons. The Recall buttons remain active so the user may

view the Delay values without risk of changing them. Internal
jumpers are available to enable or disable Bypass while in
Front Panel Lockout mode. The default setting of these
jumpers disables Bypass in Front Panel Lockout mode.

Independent bypass relays provide a fail safe, hard-wired

bypass in case of power loss.

The AVA 22d is a unity gain device with Sensitivity
controls to provide proper internal levels for the audio
converters. If the input signal is nominally +4 dBu, set the
Sensitivity control fully counter clockwise (+4 dBu). For
those unable to touch a cable and determine its signal level,
Signal present and Clip indicators provide visual acknowledg­ment that the Input signal is within optimal range.

Powered from a low voltage UL listed and CSA certified
remote power supply (230 VAC supply meets LVD 73/23/
EEC), the AVA 22d is exempt from safety agency require­ments, and may be used in any installation mandating agency
compliance.
