Listing Detail Tabs

The Loop Amplifier is a 240watt amplifier designed to drive a wire hearing aid loop installed in the floor or ceiling of a venue up to 600 m2 per amplifier.
This solution enables hearing-aid users in the area enclosed by the wire loop to hear all announcements, soundtrack or music broadcast. Hearing-aid users can set their devices to T-mode to receive the signal coming from the loop and receive excellent audio-quality announcements, without the background noise or reverberation that normally impairs intelligibility for people with hearing difficulties.

Features * High power current driven amplifier * Power output 240 watts 10A * Three mic/line inputs, one priority input (100 V) * Selectable frequency range and tone controls * Limiter and Automatic Gain Control * Integrates into voice evacuation system * Coverage around 600m2 per amplifier * Volume control for inputs 1-3 and master, treble & bass tone control * Extensive protection includes high temp, overload and short circuit

Functions
The loop amplifier can be connected to an existing mixing amplifier's line level output, or it can accept up to three microphone/line signals directly so you can use it as a stand alone system.

A 100 V priority input is available for uplink to a voice alarm system. This input can be monitored for the presence of a pilot tone.

Built-in "supervision" monitors all key functions of the loop amplifier, and the fault state is available on a fail-safe relay.

The Loop amplifier is fitted with a limiter to limit the output field strength to the prescribed 100 mA/m. This function can also be used as an Automatic Gain Control (AGC), so those soft signals are boosted for intelligibility while loud signals are attenuated so that all information is presented at a comfortable listening level. To adjust the sound to the program material and the environment, tone controls and a metal loss compensation circuit is provided.
