Configuration:
CLS2 Installation Loop Driver (4.9 Amps)
Product Overview:
The CLS2 is a professional installation loop driver capable of driving loop areas in excess of 4,300 sqft. (400 m²) with an
unsurpassed clarity of sound for both music and speech for superior intelligibility. Designed for simple discrete installation,
the CLS2 offers the most cost effective and capable solution in its class. The driver 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.

Audio
Frequency Response 80 Hz to 6.5 kHz ± 3 dB
Distortion THD+N < 0.2 %, 1 kHz Sine Wave at Full Current
AGC Optimized for Speech, Dynamic Range > 36 dB
Alert/s Alert 1: When energized, turns down the other inputs and produces a 520 Hz
square ware tone on the loop. Min/Max Input Voltage 5-24 V AC/DC, Alert 2: A
pair of contacts which when shorted turns down the other inputs and produces
a pulsed 520 Hz square wave tone on the loop.
Controls
Gain Control Front recessed input level control
Metal Loss Correction Correct system frequency response due to metal structures
Cooling Natural Convection
