SPECIFICATIONS
The compact bodypack transmitter shall be
for use with a companion receiver as part of
a wireless RF transmission system.
The transmitter shall operate within six
UHF frequency ranges, each with a 42 MHz
switching bandwidth: 516 – 558 MHz,
566 – 608 MHz, 626 – 668 MHz, 734 –776 MHz,
780 – 822 MHz, 823 – 865 MHz; transmission
frequencies shall be 1,680 per range and shall
be tunable in 25 kHz steps.

While it is ready for operation right out of the box, the
SK 300 G3 easily receives settings from the receiver via
its enhanced wireless sync function. This transmitter
also sets itself apart from others due to its unparalleled
mute options. If you want to quickly and easily interrupt
the sound signal at some point: you can simply attach
the optional external mute button to the additional
2.5 mm jack socket. This mute option is easily program-
med to provide a variety of mute options.
