Introduction

The MIPRO MR-90a is a portable wireless, receiver specifically designed for professional camcorder applications. —Matched with any ACT transmitter the MR-

90a eliminates the need for microphone cables during recording. —The MR-90a not only allows a closer combination of video and audio so that a more natural sound can be recorded, but it also ensures safer and more agile operation.

For professional camcorder

Professional ENG Receiver

To match the superb characteristics of professional camcorders and active speaker systems, the MR-90a possesses some innovative features in its design: The receiver socket has three different designs. First type can be installed directly into the reserved slot of a SONY

BETACAM ® camcorder. Second type has an external socket connection and third type has built-in AA-type battery-powered socket connection to accommodate different camcorders and active speaker systems. The performance characteristics of the MR-90E in both highfrequency receiving and audio output adopts the latest audio processing technology from the ACT series, giving it superb performance in both S/N ratio and dynamic range.

A rugged and waterproof die-cast metal housing makes the durable MR-90E the best selection in today's wireless receivers for both professional camcorders and active PA speakers.

The MR-90a 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 amplifier system. Alternatively, the MR-90a can be matched with any of the ACT-series wireless transmitter microphones to turn active speakers into wireless amplifiers.

Mount on any active speaker via velcro fasteners

Functions

The MR-90a compact, miniature receiver utilizes the

UHF band, PLL synthesized technology and true diversity design. It has a wide frequency range where 100 selectable frequencies are pre-programmed in each 24

MHz bandwidth with 16 of these specially preset into one group for use with an MA-909 interlinking transmitter.

With the world's first ACT function of MIPRO's ACTseries, the receiver and transmitter can set up a working frequency rapidly and automatically. The dual-antenna and true diversity design ensures clear and stable signal receiving with no signal dropout even in the most unpredictable operating environments. A waterproof metal case provides professional strength and durability.

A standard LCD panel gives a clear and accurate display of all digital operations and setup. When combined with the SONY BETACAM ® -series camcorders, the MR-90 can be installed directly into the reserved slot and needs no external battery or signal cable. When combined with other camcorders or active speaker systems, the MR-90 uses a designated accessory interface module which has an external DC power input or built-in battery-powered input and balanced audio output cable. The MR-90's outstanding circuit characteristics and mechanical design give it exceptional flexibility to work with camcorders, mixers, active speakers and other audio equipment.
