With optional accessories, the MR-90 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 MR-90 is a compact, miniature receiver that 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 MR90 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.
