The MIPRO MR-90a is designed to install in the wireless receiver slots found on professional video cameras. With optional accessories, the MR-90a 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-90a 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.
