The XL-50 is a loop amplifier that help users of hearing instruments to interpret speech and
music noise-free from e.g. radio or TV. To fully understand what is said is of major importance
to be able to participate in discussions etc.

The solution is XL-50. The amplifier can be fitted with a simple microphone, giving a flexible
installation. The XL-50 is also equipped with a LINE input to which the TV:s scart-plug
can be connected. The amplifiers output is automatically adjusted for either loop or headphone.
There is also an input for an external signal which activates a tone indicator in the loop.
