Wall Mounted Induction Loop Driver

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 designed specifically for wall mounting. 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 and tidy 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.


Williams AV is proud to offer Ampetronic Loop products in the United States and Canada. To purchase Ampetronic loop products in other countries, please visit https://www.ampetronic.com/
