AVT928 A

The system allows sending audio signals over long distances. The modules are a specialized transmitter / receiver that converts an asymmetrical signal into an asymmetrical signal and vice versa. Dedicated TI systems were used. Thanks to this, the construction has been simplified. The signal transmission may be via a typical twisted pair. The path can be powered by both symmetrical and asymmetrical voltages. Low distortion and noise, wide bandwidth make the set works perfectly when transmitting high-quality audio signals. Just a model application is to send a signal from a microphone located relatively far from the amplifier.

The device especially in applications where it is necessary to send audio signals over long distances
