MR-90 Professional Portable ENG Receiver

Applications of MR-90

 

Introduction

 

The MIPRO MR-90 is a professional wireless, portable receiver specially designed for professional camcorder applications. Matched with any ACT transmitter from MIPRO, this unit will eliminate the need for microphone cables during recording. The MR-90 not only brings a closer combination of video and audio so that a more natural sound can be recorded, but also ensures safer and more agile operation since it eliminates the need for awkward and bulky microphone cables.

 

The MR-90 can also be installed on an active PA speaker via its accessories and matched with MIPRO's MA-909 Wireless Audio Mixer to form a wireless inter-linking PA system. Alternatively, the MR-90 can be matched with any of the ACT-series wireless transmitters, microphones or instrument cables to turn active speakers into a wireless system.

 

The MR-90 compact, miniature receiver utilizes 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 in each 24 MHz bandwidth with 16 of these specifically preset into one group for use with an MA-909 interlinking MT-90 transmitter. 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.

 

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. Accessories like the MR-90SB built-in battery pack ensure the flexibility to work with other camcorders, mixers, active speakers and audio equipment.

Key Features

  • Waterproof, compact, and ultra-thin rugged aluminum chassis construction increases dependability.

  • 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.

  • UHF-band, PLL synthesized, dual-antenna, and true diversity technology avoids interference, improves reception and sound quality.

  • In each 24MHz bandwidth, 100 pre-programmed frequencies can be easily auto-scanned, set and locked on an open, non-interference frequency.

  • 16 frequencies are specifically preset to work with the MA-909 and interlinking transmitters.

  • World's first ACT feature automatically locks the transmitter channel rapidly and accurately.

  • Clear LCD panel shows frequency, RF and AF signal strength, function, diversity, and battery strength.

  • Control panel has setup buttons for SCAN, ACT, SQUELCH, and LOCK functions, allowing easy and error-free setup.

  • Highly sophisticated circuitry design.

  • Balanced, high-gain audio signal output.

  • Electronic power switch eliminates any noise during power up and power down.

  • Working voltage is 6~15VDC and the efficient power-saving design makes power consumption lower than 70mA.

  • Precision SMA antenna connectors with removable soft antennas.
