directly in the transmitter
Wide range of accessories adapts the
system to any requirement
Optimized PLL synthesizer and micro-
processor technology

and interferences in multi-channel ope-
ration
More usable systems per range. As the pros have known
for years, having the option of lowering a transmitter‘s
RF output power helps immensely when simultaneous-
ly operating a large number of wireless systems. This
transmitter also features wireless sync to link up to a
compatible G3 receiver automatically with a push of a
button. The revised backlit display provides a wealth of
useful information at a glance, even on the darkest of
stages.
