The Ampetronic CLS2 is the second unit in a series of induction loop drivers aimed at the demands of the electrical and audio-visual contractor.

Designed for simple discreet installation, the CLS2 is the most capable driver in its class. The ampli er is very compact, yet the most powerful unit available designed speci cally for wall mounting. All connec- tions 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 micro- phone, balanced and unbalanced line, low imped- ance and 100V - line speaker systems, plus priority alarm, doorbell or telephone connections.

Backed by Ampetronic’s standard 5 year warranty and comprehensive support services, the CLS2 is truly t and forget.

Perimeter Loops – Area Coverage (maximum)

Room aspect ratio 1:1 2:1 3:1 Maximum area m2 250 310 400

For any Induction Loop System, area coverage is dependent on
several factors. Please check these assumptions and contact Ampetronic for advice if required:
• Loop must be 1-2m above or below the receiver height
• There should be no metal structures in the plane of the loop
• Suf cient voltage to drive the loop – check the cable table below

Maximum Cable Length

The CLS2 is designed for SINGLE TURN loops for optimum audio quality: • Loops with DC resistance from 0.2O
• Impedance up to a maximum of 1.3O

Maximum cable length is dependent on cable type and on the application:

Cable type

2.5mm2 copper
4.0mm2 copper
1.8mm2 at copper tape

Wall mounting, secured by 4 screws

The CLS2 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 ampli er can be installed in the most constrained spaces.

Mounting

Designed for vertical panel mounting using 4 screws (6 holes provided). Template for screw placements provided. The CLS2 is compact enough to t on a 1U rack tray with feet removed.

Enclosure access

Hinged lid, secured by 2 Phillips PH2 screws. Lid can be removed completely if required, for ease of access, or if there is no room to hinge the lid forwards.

Cable routing

Knock-outs (diameter 20mm) are provided for routing cables into the enclosure. 2 on the top edge, 4 on the rear face, 4 on the bottom edge, providing excellent installation exibility.

Cable connections

All input cable connections are made with screw terminals mounted on one side of the PCB. Mains power connections are made to a chassis mounted screw terminal block. Loop connection is made to a screw terminal pair mounted on the PCB. Cable connections are illustrated on a detailed label on the case interior.

Indicators

3 LED indicators are visible with the case open or closed:

  • AGC Amber LED lit when input signal is activating the automatic

    gain control

  • Current Green LED lit when current is running in the loop

  • Power Green LED lit when the unit has power

    Controls

    Five controls are located to be accessed only with the lid open, all screwdriver adjustable.

  • Level controls for inputs 1, 2, 3 and 4

  • Metal loss correction

  • Loop drive current

Issue no UP36401-4

Standards Compliance

The CLS1 is CE marked to all relevant safety and EMC standards, including EN60065 and EN55103. Safe operation is subject to correct installation. The CLS1 will meet the requirements of IEC60118-4 and the relevant recommendations of BS7594 if speci ed and installed correctly.
