Ampetronic CLS2

The Ampetronic CLS2 is a wall mounted induction loop amplifier providing coverage of up to 400m². Coverage varies according to room aspect ratio, so please contact us for advice if you are unsure which loop amp would be best for your project.

The compact, slimline tamper resistant enclosure can be discreetly mounted on a wall and all connections and controls are secured behind a hinged, detachable cover. Once the cover is screwed closed, there is no access to the cable connections or controls.

Input options on the Ampetronic CLS2 are comprehensive, with four independent inputs for balanced microphone, balanced and unbalanced line, low impedance and 100V - line speaker systems, plus priority alarm, doorbell or telephone connections.

3 LED indicators on the front of the cover show the power, current drive and auto gain control status.
