Carrier Balance
If your rig has carrier balance it acts as a type of mic tone control. It is
best to listen to yourself in another receiver as you transmit into a dummy
load. You are actually moving the carrier + or - 200 Hz above or below the
center of the filter network, which causes your microphone audio to change its
tonal quality.
The use of the AD-1 series mic adapters allow simple interface
with popular transceiver inputs. The adapter is 6” long and has a 1/8” female
input jack for the boomset microphone and a 1/4” female that is for the PTT
(push to talk) line for the Heil foot switch or hand switch. The 1/4” stereo
plug goes into the headphone jack on the transceiver front panel.
All Heil Pro Micro Boomsets are shipped with foam windscreen
that fits over the microphone. The windscreen does not change the frequency
response, just the breath blasts directly into the microphone.
Some state laws prohibit the use of headsets while operating
a vehicle. Please check with your local regulations and restrictions prior to
usage of this product while operating a vehicle
