Quad clean switch sub module four independent clean switches per 9435. Add a 9435 or 9435-4CS sub module to the system for clean and quiet switching. The 9435 provides clean and quiet switching for up to two independent destinations while the 9435-4CS provides for four destinations. A single sub module may be added to the base 9430 8×2 router module. A second sub module may be added to expanded systems, providing clean and quiet switching for up to eight independent destinations. The Avenue router utilizes video frame synchronizers rather than line delays to ensure perfect alignment of mis-timed and completely non-synchronous SDI sources. In addition, the unit’s frame synchronizers continue to output black if the input signal goes away. This ensures continuity of the router’s video output signal, a significant benefit if the router is feeding an MPEG encoder.

Glitch-free, quiet switching of embedded audio signals requires synchronization and alignment of audio sources at the input to the switcher. With the Avenue router’s clean and quiet option, digital audio is de-embedded, and if it is linear PCM, sample rate converted, switched, and re-embedded. Encoded audio streams such as Dolby™ E are de-embedded and re-embedded but not processed in any way.
