Hang (ms): To keep the AGC system from doing too much up/down, an adjustable hang time is
provided. After this time has expired, the Decay will then determine how quickly the AGC gain
recovers.
Hang Threshold: The hang will NOT occur if the signal is weaker than this threshold.
Fixed Gain: When you choose Fixed AGC on the front panel, this number is used to amplify the
signal.
Leveler
The Leveler is intended to even out the variations in input to your microphone caused by varying distance
from or angle presented to it. It is an attempt to “level” the amplitude presented to the rest of the DSP audio
processing. The leveler is disabled in DIGU and DIGL modes.
ALC
The ALC is what you would typically consider ALC to be in a transmitter. It is an attempt to prevent
overdrive of the amplifier and the distortion that would accompany that. Because of the “dual channel”
AGC algorithm we use, this ALC will allow very high average power while maintaining peaks at a
controlled level. The Compressor and Compander (CMP and CPDR on front console (mode specific –
phone) and on the Setup Form-Transmit Tab) work very well with the ALC to increase average power
without overdrive.
