Squelch functionThe squelch function can reduce, suppress, or eliminate useless noise, so that it will not pass through the speaker When it comes out, the voice of the call can be retained (even under the weak signal in the case of loud noise).
CTCSSCTCSS is a different frequency signal attached to the main transmission frequency. If different sub-tones are set, the signal will be masked to prevent outside interference.
Frequency-HoppingUsing the frequency hopping function can prevent monitoring and make communication more encrypted and anti-interference
Audio compression, expansionThis function can effectively compress part of the transmitted setting signal before transmitting to the other end, and then expand the signal at the receiving end, thereby maximizing the signal-to-noise ratio of the intercom. Make the voice clearer.
Large speakersUsing 40mm large speakers, loud and clear.
