SYSTEM OPERATION AND SETUP WIRED AND WIRELESS OPERATION Powering the MPA-400 WIRED OPERATION Turn on the unit using the Power ON Switch (9). The Power ON LED (12) indicating the MPA-400 is receiving power. The MPA-400 is powered internally by the 12V/3.3A rechargeable battery.

SYSTEM OPERATION AND SETUP Note: If using more than one wireless microphone on the same frequency, switch only one on at a time. Microphones on the same frequency will interfere with each other. However, one wireless microphone can be used with two or more MPA-400 wireless receivers on the same frequency simultaneously to increase overall sound level. Observe care in selecting volume, transmitter location and speaker placement so that acoustic feedback (howling and screeching) will be avoided.
