It delivers 3.5ARMS with AGC optimised for speech and adjustable metal loss correction, sized for small to mid-size perimeter loops. Wall mounting suits rooms where no rack is available, which covers most meeting rooms and smaller houses of worship.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003ePerimeter loop drivers are selected on loop area, aspect ratio and the metal loss measured during survey, not on room capacity.

AGC is optimised for speech with more than 36dB of dynamic range, which keeps output consistent as the input level varies through a session. Metal loss correction is adjustable from 0 to 3dB per octave to compensate for steel in the floor or ceiling structure. Wall mounting removes the need for rack space. The higher output CLS2 is available where the loop area or measured metal loss requires more current.\u003c\/p\u003e\u003cp\u003eLoop conductor and terminations are ordered separately: \u003ca href=\"https:\/\/creationnetworks.net\/products\/listen-technologies-la-396-14-b-14-awg-hearing-loop-cable-black-spool\"\u003e14 AWG hearing loop cable\u003c\/a\u003e for perimeter runs, \u003ca href=\"https:\/\/creationnetworks.net\/products\/listen-technologies-la-398-foil-to-cable-crimp-lug-14-16-awg-12-pack\"\u003efoil-to-cable crimp lugs\u003c\/a\u003e where copper foil tape meets cable, and \u003ca href=\"https:\/\/creationnetworks.net\/products\/listen-technologies-acex01-pvc-protective-extrusion-3m-x-50mm-grey\"\u003ePVC protective extrusion\u003c\/a\u003e where the loop is surface run.\u003c\/p\u003e\u003cp\u003eCommissioning is a measurement exercise against IEC 60118-4, not a listening check.
