PROC Processor Switch
This button enables the Parametric Microphone Equal-
izer and Speech Processor for SSB/AM transmission.
When the Parametric Microphone Equalizer is acti-
vated, the " " icon appears in the display.
When the Speech Processor is activated, the "
and " " icons appear in the display. Adjustment
of the Processor level is accomplished using the
[ PROC ] knob.
A :
The Speech Processor is a tool for increasing the
average power output through a compression tech-
nique. However, if the [ PROC ] knob is advanced
too far, the increase in compression becomes
counter-productive, as intelligibility will suffer. We
recommend that you monitor the sound of your sig-
nal using the Monitor (with headphones).
When the optional DMU-2000 Data Management
Unit is connected, you may use the Audio Scope/
Oscilloscope page to help you adjust the setting of
the compression level of the Speech Processor for
optimum performance using your voice and micro-
phone.
