The VL1/B1 is a 12 volt induction loop kit for use in vehicles. This kit has an approximate coverage of 1.2 metres square and is supplied with a VL1 mini 12V amplifier, AL8 cigarette lighter power connector, TX2 loop cable and AMT microphone.
new VL1 induction loop amplifier is specifically designed to help hearing aid users communicate more effectively in cars, taxis, buses , elevators and other motor vehicles.
12V vehicle induction loop kit ; includes VL1 mini-12V amplifier, AL8 cigarette lighter power connector, TX2 loop, AMT mic.
The VL1/B1 1.2m.sq. 12V vehicle induction loop system is ideal for cars, taxis, buses and other private/commercial vehicles.
The kit includes a compact mini-induction loop amplifier with keyholes for dashboard mounting, a cigarette lighter power adaptor, an AMT microphone, a pre-formed loop and an ‘AFILS fitted’ sticker.
Metal compensation control helps combat the frequency response problems caused by metal ‘absorbing’ the magnetic field.
