ISA 250

Induction loop amplifier


Description:


The induction loop amplifier ISA 250 powers induction loops inside rooms. Reception loops are built into most hearing aids. The audio signal from the induction loops is much better for the hearing impaired than the acoustic signal.
This is the result of the broad frequency spectrum fed into the loop and the compression used in the amplifier that enables the hearing impaired to hear low level music or speech.
The new ISA 250 is adjustable for room sizes up to 1000 sqm, 500 sqm, 200 sqm or 100 sqm. Therefore only one model covers all applications.
