Auto - the bias voltage is only applied when a talk is enabled.The bias voltage is a small voltage of 2.5V that can be switched on to power an electret microphone on a headset. set the gate hold to a comfortable time.set gate threshold so that background noise is just cut of.this option is only available when the gate threshold is not OFF Options together with a correct set threshold the gate will nearly not be heard. the release time can be set with the gate hold. The gate releases as soon as the audio is above the set threshold. It will turn the mic off when the user stops talking. A correctly set gate will only "open" the microphone when a user is talking. This is very use-full to keep the intercom system quiet and calm. The gate cuts of audio when below the set threshold. when enabled the release time of the compressor can be set. The compressor reduces the dynamic range off the input signal by reducing the louder parts of the signal. Make sure that the gate is not triggered when speech is at a low level To cut off background noise the gate can be set. ![]()
