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:

1. Press the'SCAN'button and the receiverwillauto-scan
and lock on tooneofthe16preprogrammed
frequencies.
2. Press the'ACT'button to automaticallyupload the
receiver frequencyto your transmitter.
3. Once the frequency pairing hasbeen set,thedatais

7. The receivers output level and dynamic rangehave been
accurately factorycalibrated tomatchthemicrophone
capsule's sensitivity,ensuring optimalperformance from
the system.(1.5dBtolerance).
8. The modular designallowsforeasyinstallation,
maintenance and DIY.
(1) Turns the
receiver module on and off. After powering on, the AF
LED will flash. Turn the knob clockwise to increase
volume.
(2) Indicates the audio
signal level.
(3) Enables you to adjust the
receivers sensitivity to ensures that no spurious noise
is heard when there is no transmitter signal present.
(4) Press to setup the transmitter frequency
to match the receiver frequency.
(5) Press to select the receivers frequency
and to auto scan to ensure an interference free
channel.
(6) Display the channel selected for
the receiver.
(7) Indicates if there is interference
present .
(8) Indicates the RF signal
strength at the receiver.
