Henry Engineering Offers Multi-Purpose Switcher/Silencer

Henry Engineering debuted its AutoSwitch automatic audio switcher and silence sensor, which it says can be used to manually or automatically select between two stereo audio sources, anywhere an A/B audio switcher is needed.
Common applications for AutoSwitch include use as a monitor-source switcher, enabling the operator to avoid the problem of “digital processing echo” by monitoring audio switches from Air to Local when the mic is on; and as an automatic backup audio switcher, where the unit senses loss of the main audio source and switches to a backup source until the main audio source returns to normal levels.
Each of the two silence sensors has adjustments for setting the silence threshold and delay time. If the main source level drops below the threshold for the time set, the silence sensor trips and the unit switches to the backup source. When the main source returns, the unit resets and switches back to the main source.
AutoSwitch has an Alarm relay output to activate an external alarm or other equipment. LEDs indicate which audio source is active, when a channel’s audio is below the silence threshold and when the silence sensor has tripped. The silence sensors can be disabled for manual control, as can the Alarm relay, with automatic audio control still active.
The unit is 1/3 rack width and can be rack-mounted with the optional rack-mount shelf, or cabinet- or wall-mounted using optional mounting brackets. AutoSwitch is powered with a built-in AC power supply.
