AD22S by Rane

The Rane AD22S is a fully balanced two-input, two-output Audio Delay unit designed for multiple applications - such as speaker array synchronization and precision audio-to-video alignment. The channel settings can be saved individually, are always saved into working memory, and will be restored upon power up if the unit shuts down unexpectedly. Remote recall connections on the rear of the unit let you connect standard switches to recall settings remotely.  The AD22S can operate as two independent channels or as a linked or stereo pair, and the balanced XLR inputs and outputs allow for 24-bit processing and delay precision down to 0.01 ms.
