Wall Mounted Induction Loop Driver

Designed for simple discrete installation, the CLS1 offers the most cost effective and capable solution in its class. The amplifier is very compact and 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 comprehensive, with three independent inputs for balanced microphone, balanced and unbalanced line, low impedance and 100V – line speaker systems.
