Adjusting PA calibration manually
If needed it is possible to calibrate the full duplex performance. The calibration value can be set
to AUTO or be adjusted manually in steps from 0 to 5 where 0 is the highest grade of duplex.
• Increase the calibration if the remote party experiences disturbing echoes.
• Decrease the calibration if the remote party experiences low duplex, i.e. your voice is muted
or clipped when the other party is speaking.
The position of the PA system’s microphones and speakers and the amplifier’s settings may
affect full duplex performance.
