CLS2
|
| Product Name
|
Installation Loop Driver, 4.9 Amps
|
| Overview |
| The CLS2 is a
professional installation loop driver capable of driving
loop areas in excess of 4,300 sqft 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 |

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 |
