Portable Receivers
MR-90a Professional Portable ENG Receiver
New!
The MIPRO MR-90a is designed to install in the
wireless receiver slots found on professional video cameras.
With optional accessories, the MR90 can be configured five
different ways to fit all types of camcorders such as the Sony
Betacam series or Ikegami and other compatible camcorders.
The MR90 compact, miniature receiver utilises
the UHF band, PLL synthesized technology and dual-antenna true
diversity design, ensuring clear and stable signal reception
with no signal dropout even in the most unpredictable operating
environments. It has a wide frequency range where 100 selectable
frequencies are pre-programmed. With the world's first ACT
programming function of MIPRO's ACT Series, the receiver and
transmitter can set up a clear working frequency rapidly and
automatically.
A weather-resistant metal case provides
professional strength and durability. A standard LCD panel gives
a clear and accurate display of all digital operations and
setup.
The MR90a can also be installed on an active PA
speaker via MA-909 wireless mixer, MT-90A wireless interlinking
transmitter or ACT transmitters to turn active speakers into a
wireless system.
Waterproof, compact, and
ultra-thin rugged aluminum chassis construction.
-
Various interface socket modules can be
easily detached and installed to work with different
camcorders, active speakers and other audio equipment.
-
Detachable battery pack accessory needs
only two AA-sized batteries to provide at least 10
continuous hours of operation, eliminating the need for
external power.
-
True diversity technology for best
reception quality.
-
100 pre-programmed frequencies can be
easily auto-scanned for a clear, interference-free
frequency.
-
ACT™ syncs the transmitter and receiver
frequency automatically.
-
LCD panel shows frequency, RF and AF
signal strength, function, diversity, and battery strength.
-
Electronic power switch eliminates any
noise during power up and power down.
-
Working voltage is 6~12V DC and the
efficient power-saving design makes power consumption lower
than 70mA.
-
Precision SMA antenna connectors with
removable soft antennas.
