It is important to prevent under-driving or
over-driving the handheld transmitter input
stage. Pay special attention when matching
the transmitter input sensitivity to this micro-
phone head.
Adjust the transmitter sensitivity to a level
where the audio path meter on its companion
receiver shows 75%-95% full on high-empha-
sis vocal peaks for optimal signal strength
and quality.
