The LA-75 loop amplifier uses constant current technology with volume compressor for operating inductive loop hearing systems. These allows users of hearing aids with a T-coil or inductive receivers to receive audio signals. The LA-75 loop amplifier has many advantages over mains operated loop amplifiers as it, can be used in many installations were mains power is not available, tents, activity centres as interpreting facilities, for lectures or tours. We stock four different colours of loop wire, available with 1.0, 1.5 and 2.5mm² cross sectional area.

Adastra LA-300 loop amplifier has 3 input channels which will accept either XLR, 6.3mm Jack or RCA sockets.
