The Ampetronic CLS1 is a Wall Mount Perimeter Induction Loop Driver, for areas of up to 400m² and aimed at the demands of the electrical and audio-visual contractor. Its enclosure is designed for simple, permanent installation with secure lid protecting connections and controls (while leaving operation indicators visible). The case is designed to make access simple, and to ensure the amplifier can be installed in the most constrained spaces.

Designed for simple discreet installation, the CLS2 is the most capable driver in its class. The amplifier is very compact, yet the most powerful unit available. All connections and controls are secured behind a tamper resistant, hinged, detachable cover. Combined with its small size, the range of mounting and cabling options ensure that installation is convenient in any environment. Input options are extensive – 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.
