Graham-Patten ADLY-4 solves AV sync problems
The Graham-Patten ADLY-4 correctly times a digital audio data stream to the digital video data stream for delivery of correctly synchronized audio/video — whether using SDI or HD-SDI video.
Both the ADLY-4A (balanced AES3 I/O) and ADLY-4B (unbalanced AES3id I/O)offer up to eight channels (four AES pairs) of inputs and delayed outputs.
The ADLY-4 is well suited for digital AV installations where the video path length is longer than the audio path length. Users can dial in up to 99.9 frames of delay in increments of .1 frames, using the X0.1, X1 and X10 frame delay selectors, and set frame rate with the FPS selector with 24, 25, or 30 FPS. The ADLY-4 provides an external looping AES3id reference input. It also can be switched to internal reference.
