DIVERSITY RECEIVER MODULE
DIVERSITY RECEIVER MODULE
The MRM-70 is a wirelessmicrophone receiver
module suitable for installation in MIPRO's MA-705,
7 0 7 & 909portable PAamplifiers. Itcan also b e
fitted to other PA amplifiers, mixers, signal
processors a n d karaokeplayers to provide these
devices with frequency agile, wireless reception.
The UHF band and PLL technology are utilized
to avoid the often congested VHF band. True
diversity and advanced circuitry combine to
eliminate signal dropouts andrandom noise
interference. The main features and benefits o f the
MRM70 are:
