Rane AVA 22d Audio to Video alignment delay £759.99
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. 24-bit 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.

Technical Specifications
- Application Information
- The AVA 22d provides a cost-effective solution to the problem of aligning audio to video in broadcast. Audio preceding video by even one frame is detectable by some people. The high cost of existing audio/video synchronizers prevents many broadcasters from correcting all synchronization problems adequately. Satellite links also add to the synchronization problem since the audio can be transmitted through a separate medium than the video. An additional problem is the inherent HD video processing delay found in HDTV monitors at home, which varies by manufacturer and model. The AVA 22d’s maximum delay of 9.5 NTSC or PAL/SECAM frames provides any of these complex systems with a cost effective delay solution with very high quality.
- The AVA 22d operates as either a dual mono or stereo device. Link mode provides simple stereo operation, linking both channels together with easy one-button editing of both channels’ parameters. In dual mono mode the two channels are completely independent allowing simultaneous operation in two separate mono production rooms. The Remote Recall terminals can be internally configured allowing the remote room to independently access the two configuration memories.
- The AVA 22d supports both NTSC and PAL/SECAM broadcast modes. This broadcast mode is stored in configuration memory with the delay values allowing recall of NTSC values from one memory and PAL/SECAM values from the other. Video houses providing NTSC to PAL (and vice versa) conversion find this feature particularly useful. (Those working on Godzilla sequels should contact the factory for special synchronization procedures.)
