Product Description


The AAF5 can be widely applied to external audio processing of all types of receiving equipment such as radio transceiver, receiver or broadcast radio to effectively reduce background noise by more than 10 dB, improve the signal-to-noise ratio by 20 dB, and increase the overall all signal readability on the RS and RST scales.
