This section describes each of the controls on the control panel.

80Hz/250Hz/500Hz/1.2kHz/3kHz - Equalizer frequencies. Level -6dB +6dB
COMP- Compressor level
MIC - Microphone gain amplifier (minimum level -6db, maximum level + 20db)
OUT - adjustment level output signal (dependent on the mic gain in your transceiver)
Led COMP LEVEL - this led lights up when you signal start to compress. If led blinks rarely when you speak - it is easy compression, if led blinks often or light all the time when you speak - it is hard compression. (Led must to light one time, when you connect Equalizer to transceiver).
