Portable Receivers
MR-90 Professional Portable ENG Receiver
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.
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.
