LOOP AMPLIFIERS
|
LA-40 Active Loop Amplifier |
| |
Active loop amplifier,
with volume compressor, specifically for setting up an inductive hearing system in domestic locations.
The loop amplifier LA-40 transmits the audio signals from a TV, audio system, and/or microphone to the inductive loop which is laid on the floor, wall, or along the ceiling. Thus, a magnetic field is created within the loop which is received by the T-coil of the hearing aid or the inductive receiver and is then converted again into an audio signal.
The wireless transmission is an advantage of inductive hearing systems. It makes it possible for the user to move freely within the loop and to adjust the volume of the hearing aid or receiving unit (LR-200) as desired, without disturbing the other occupants.
The LA-40 can be connected directly to the SCART jack of a TV (via supplied SCART adapter) or to an audio system. Talks of the other occupants can be heard via the connection of a microphone which is available at option.
The integrated signal generator of the LA-40 allows to create an alarm signal via an optional switch.

LA-75 Active Loop Amplifier |
|
Active loop amplifier,
in constant current technology with volume compressor for setting up an inductive hearing system.
The inductive transmission of audio signals allows users of hearing aids with a T-coil or inductive receivers, like e.g. the LR-200 to receive audio signals. The wireless transmission is an advantage of inductive hearing systems which makes it possible for the user to move freely within the loop.
Inductive hearing systems are used for various applications, e.g. as a hearing aid for the hearing impaired in churches, theatres, cinemas, waiting rooms and lounges, as interpreting facilities, for lectures in museums, exhibitions, etc.
At inductive hearing systems an inductive loop, made of a wire winding which is laid on the floor, wall, or along the ceiling and is controlled by a constant current amplifier. Thus, a magnetic field is created within the loop which induces a voltage into the T-coil of the hearing aid or into the inductive receiver. In the receivers, this voltage is then converted again into an audio signal.
- Stable metal housing, small design
- Suitable for 12V battery operation or PSU 12V DC current /5A which is available at option
- Volume compressor
- Automatic talkover
- Metal loss correction 0-(+3)dB/oct.
- Please order matching PSU PSS-5000 together with this unit
