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.

WIRELESS MIXER Operating Manual G、How to Setup Wireless Interlinking Transmitter: 1. To change transmitting channel, hold channel button on the front panel for 2 seconds. After numeric LED starts blinking, press channel button again to change preset channel. At this stage, channel will be changed when you press the channel button. 2. When numeric display has changed to one's desired channel, simply release the button and channel setup is completed after numeric LED blinks six times.
WIRELESS MIXER Operating Manual 2. CD Player installation： A. Remove screws holding the blank panel and remove the panel (see Fig. 3-1) B. Insert the CD player into the mixer (see Fig. 3-2) C. Reinstall screws to secure the player (see Fig. 3-3) Fig. 3-1 Fig. 3-2 Fig.
WIRELESS MIXER Operating Manual 3. Operation Notes and Precautions: 1. Microphones have priority over music inputs. When music is playing and a microphone receives an audio signal, the music will be muted. As soon as there is no longer an audio signal to the microphone, the music will fade in. 2. Although the same frequency band may be used, it is important that the frequency of the MT-90 transmitter and the MRM-70 receiver module are not the same. Otherwise, the MA-909 will not operate properly. 3.
