MA-909
Instruction Manual
ELECTRONICS CO., LTD.
WIRELESS MIXER
Operating Manual
The traditional design concept of the portable "all-in-one" wireless amplifier
consists of a unit with a CD player, cassette player, wireless receiver, and control
mixer mounted inside the active speaker cabinet. Although it is easy to use and
convenient for low power portable amplifier systems, this design is not suitable for use
in high power amplifier systems. It will not only be limited in its function and
performance, but it will also be inconvenient to operate. You can imagine how
inconvenient it is running to the speaker system far from you just to adjust the volume
or change a cassette or CD. To solve the inconvenience of operating such a high
power system and to incorporate its user-friendly functions into all operations, MIPRO
leads the market by designing the first integrated wireless interlinking amplifier system.
This new system separates the control mixer unit from the active speaker system.
The mixer unit contains a built-in high-fidelity wireless interlinking module which
transmits the mixed audio signals to the active speaker system. By doing so, users
can conveniently operate the system from the nearby "wireless mixer" instead of
running to the remote speaker system. In addition, the MA-909 wireless mixer can
transmit the mixed audio signals simultaneously to any active speaker system
equipped with an interlinking receiver module, without any connecting cable and with
total disregard to the quantity, specifications, or brand of speakers. Not only does the
MA-909 ensure compatibility with any existing PA system, but its agility in expanding a
system's output power or sound field provides maximum maneuverability and ease of
operation.

EIA Standard 2U metal case equipped with 2 built-in 16 frequency wireless microphone
system, high fidelity wireless interlinking transmitter, CD player, wired microphone socket,
LINE-IN socket for other audio sources, and LINE-IN/OUT sockets for recording.
A wired microphone, two wireless microphones, CD, cassette player, and other audio
sources can be mixed simultaneously at the input.
A separate wireless control mixer unit allows users to control active speaker systems
remotely to achieve the best performance.
Sixteen preset transmitter frequencies make selecting an interference-free frequency
simple and convenient.
The modular design of the interlinking wireless receiver allows it to be either built-in or
mounted on specific brands of active speaker systems.
Interlinking receiver modules installed on active speaker systems allows unlimited
expansion and change of setup position within the transmitter's range.
