The SoundPals™ ADLY-4 is an easy-to-use and cost-effective solution for systems timing problems where audio to video synchronism is paramount. Both the ADLY-4A (balanced AES3 I/O) and ADLY-4B (unbalanced AES3id I/O) offer up to eight channels (4 AES pairs) of inputs and delayed outputs. These problem solvers are ideal for digital audio/video installations where the video path length is longer than the audio path length. Dial in up to 99.9 frames of delay in increments of 0.1 frames, using the X0.1, X1, and X10 frame delay selectors. Set frame rate with the FPS selector with 24, 25, or 30 FPS. The ADLY-4 provides an external looping AES3id reference input, or switch the unit to internal reference and use input number one. Front panel LED indicators show inputs validity, external reference presence, and power.
Housed in the familiar SoundPals compact, rugged aluminum enclosure, they use independent power supplies, or mount up to three units in a 1RU rack mount frame with a central power supply.
