The
MA855/R850A
and
MA853/R850A
kits are wireless micro-
phone systems of the Diversity UHF type featuring high performance
levels and PLL technology. They enable selection of 120 channels for
maximum flexibility. The “Diversity” technology of the receiver and the
microphone antenna ensure an exceptionally broad range for maxi-
mum reliability of the signal and freedom of movement.
Both transmitters (MA855A with a handgrip and MA853A pocket mo-
del) have a handy mute function, an LCD display, a keypad lock and a
battery-status indicator.
The R850A receiver, which has its own power supply, is equipped with
an automatic scanning system for identifying the frequency of the mi-
crophone, a large LCD display, an RF/AF level measuring device and a
squelch circuit that enables any interferences present in the surroun-
ding environment to be eliminated.
