Description Specifications
 
The ALS602 Audio Loss Switcher is a device that monitors a stereo or monaural audio input and switches to a secondary audio input when the audio fails. The unit can be connected to work with dual mono or stereo audio. A loss of audio triggers the audio switch after a field programmable time delay. This allows for normal pauses in the audio programming material. A time delay can be set from 1 second to 64 minutes.
 
 The switch will transfer stereo or mono audio from a secondary source when the primary audio has failed and the count-down time delay has been reached. If the audio is restored before the count-down time delay has been reached, the system will reset the counter and wait for the audio to fail. The unit has a front panel switch that allows the operator to program AUTOMATIC return to primary when the primary audio is restored.
 
The front panel switch can also select HOLD that will switch when the primary audio fails and keep the switch in the secondary audio position until manually reset by the operator, or the switch can be moved to RESET that will keep the audio on the primary feed for testing purposes. A green L.E.D. on the front panel indicates that audio is active. A red Alarm L.E.D. on the front panel indicates the switch is in the secondary position. The audio inputs and outputs are balanced and can be used with balanced or un-balanced audio sources. All audio connections are made on the removable screw terminal at the rear of the unit.
 
An additional relay output is available on a rear panel RCA connector to control a video switch so video can be switched with the audio. This unit has two independent mono audio loss detectors and switches on-board. When stereo is required both sides are connected together with a program jumper located on the pc board to form a stereo detector. In the stereo mode both audio inputs move together. The ALS602 is a dual mono or stereo card that fits into a PMS610 mainframe with a built-in power supply. The PMS610 Mainframe and power supply occupy one 19" rack space. This mainframe will hold up to three ALS602 cards. This allows for six mono or 3 stereo switches to be put into one mainframe space.
