Adastra RMC120 SERIES User Manual page 6

If the VOX feature is enabled, audio playback through channels 4 and 5 will be reduced in volume
automatically when speaking into MIC 1.
In addition to channel and MASTER volume controls, there are BASS and TREBLE EQ controls to adjust the
tone of the overall output. At the 12 o'clock position, these controls are applying no effect to the signal (no
boost or cut). Moving the BASS control clockwise boosts the low frequencies in the audio, whilst moving it
anticlockwise will cut these low frequencies. Likewise, moving the TREBLE control clockwise boosts the high
frequencies in the audio, whilst moving it anticlockwise will cut these high frequencies. Adjust these EQ
controls to suit the type of audio signal or compensate for the room acoustics.
