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.
