The LE-175 DG-MA Monitor/Talkback Amplifier from Louroe Electronics is a companion unit to DG Series’ DG-12II and DG-25III alarming base station models. It provides two-way listen/talkback communications between the base station and the remote speaker/microphones in the audio system.
The LE-175 Monitor/Talkback Amplifier is equipped with an "All Call" feature that allows a security personnel to address all zones simultaneously. This DG-MA supports up to 10 DG-25III base stations for a total of 250 zones. For audio systems larger than 25 zones, an external amplifier is recommended, which will boost "All Call" capabilities. Moreover, this Monitor/Talkback Amplifier has a 3" (76mm) built-in speaker for monitoring audio and a hand-held dynamic microphone for talkback to remote zones and "All Call" facilities.
This DG-MA Monitor/Talkback Amplifier has monitor and talkback level controls, input/output jacks for recording and playback from a standard (2 hour) VCR, and a headphone jack. Furthermore, the LE-175 DG-MA is standard 19" (482mm) rack mountable.
As part of the alarming audio monitoring system, this DG-MA provides bi-directional communications with the remote speaker/microphone that monitor stairwells, elevator cabs, lobbies, public access buildings, parking structures, and juvenile detention centers.
