RANE AUDIO VIDEO ALIGNMENT DELAY AVA 22d
- Brand: RANE
- Model Number: AVA 22d
- Product Code: BS16852
- Quantity in stock: 4
Rane AVA 22d is a fully balanced two Input, two Output Audio / Video Alignment Delay providing a range of 0.0 to 9.5 NTSCor PAL/SECAM frames on each Output. 24-bit audio converters provide excellent sound quality. • 0 to 9.5 NTSC or PAL/SECAM Frames Delay per Channel • Two Independent Channels (2 In - 2 Out) • Single-Field (half-frame) Increments • Independent Remote Memory Recall Interface on Rear • Two EEPROM Memories per Channel (No Batteries)
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.

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 videoprocessing delay found in
