The AES-403 Two Input Automatic Multi Switcher with integrated silence sensor.

The AES-403 is a two input AES3 compatible digital audio switcher or can be configured to accept an analog balanced left/right pair on one channel forming an analog/digital switcher combination. Similar to the BDI AES-402 the unit has a silence sensor and can be programmed to automatically switch to an alternate path in the event of channel loss due to silence or digital errors. Uses include EAS audio injection for plants supporting analog and AES3 audio distribution for broadcast or virtually any application where switching between analog and digital audio paths are desired. Or use as a two input digital switcher, the choice is yours.  All AES-403 Multi Switchers come with silence sensors.
