Art Pro Audio MACROMIXE4 4 Channel Personal Mixer

Problem:​ You need to add 3 mics to a mixer, which only has one available channel.

Solution:​ Insert a ProMIX between the mics and the mixer. Each mic channel on the ProMIX has both phantom power and low frequency cut selectable via DIP switches plus a level control. The balanced XLR line output can be connected to a mic input on the mixer and headphones, or a powered monitor can be connected to the Phone/Aux output. And if AC power is not available, the ProMIX runs on batteries as well.

How to use:

1. Connect the AC adapter cable to the 12V DC Input on the MacroMIX and plug the other end into a 120V AC power outlet.
2. Connect your various signal sources to the appropriate Inputs on the MacroMIX with unbalanced shielded cables. Electric instruments or amplifier line outputs would go to the 1/4 input on channel 3 and/or 4. Stereo sources (tape deck, CD player, etc.) would be connected to the RCA Inputs on channels 1 and 2.
3. Connect headphones to the Line/Headphone output. Alternatively, this jack can be connected to the stereo inputs of a powered monitor speaker or a headphone amplifier if added headphone loudness is required.
4. Connect the MacroMIX's stereo RCA Outputs to the L&R inputs on your tape deck, PC, or a PA mixer with stereo inputs.
5. Adjust the Level controls for the desired mix.
