MR-90a Professional Portable ENG Receiver New!

Applications of MR-90a

 

Introduction

 

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.

Key Features

  • 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.
