Introduction
The MIPRO MR-90a is a portable wireless, receiver
specifically designed for professional camcorder
applications. —Matched with any ACT transmitter the MR90a 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 MA909 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

Professional ENG Receiver
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.
