CTL-PB1– Toggle Compressors
This function is accessible via Main Diagnostics mode select (CTL-
PB1
), and allows the microphone
(
PB1
) and audio receive compressor (
PB2
) to be enabled or disabled. The factory default is that both
compressors are enabled.
It may be desirable, depending on background noise, that the compressor contributes to the noise floor of
the microphone and/or receive audio. To reduce this possibility, the compressor for each can be
disabled. However, care must be observed in the setting of the receive and microphone sensitivities since
clipping of high-level audio signals is possible with the compressor disabled.
PB1 – Toggle Microphone Compressor On/Off
This mode allows the microphone compressor to be enabled or disabled:
Button(s) Toggle Microphone Compressor On/Off
PB1 Toggles the microphone compressor on and off.
TRANSMIT Exits the toggle microphone compressor mode and returns the unit to the toggle
compressor screen.
PB2 – Toggle Audio Receive Compressor On/Off
This mode allows the audio receive compressor to be enabled or disabled:
Button(s) Toggle Audio Receive Compressor On/Off
PB2 Toggles the audio receive compressor on and off.

compressor screen.
