User manual ROLLS MX56

OPERATION Connect your various devices such as a laptop computer, wireless microphone, or other line level devices to Inputs 3 and 4. Remember Channel 4 is MONO, and Channel 3 is STEREO. Connect a stereo signal source such as a CD player, cassette player, or a video player's audio output to Channel 1, and a microphone to Channel 2. If the microphone requires phantom power, move the phantom power jumper as described on the previous page. Adjust the levels of each channel for a desired balance of signals. Since the MX56c has no master level, you will need to be aware of the setting of your amplifier. Check each mic/source level individually first for proper level, then adjust them for a desired mix. 4-Channel Mixer MX56c MiniMix A/V Rolls Corporation Salt Lake City, UT 10/05 SCHEMATIC Owners Manual INTRODUCTION Thank you for your purchase of the MX56c MiniMix A/V.
