ART ProMIX Three Channel Portable Battery Powered Microphone Mixer w/ Phantom Power & Headphone Amp

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

• If you are using the 12V AC adapter, connect the cable end to the ProMIX's 12V DC input and plug the other end into a 120V AC outlet. Otherwise, make sure there are two 9V batteries connected inside the battery compartment.
• Connect low-impedance mics to the 3 XLR inputs with mic cables.
• If any mics require phantom power, set the appropriate Phantom DIP switches to the on position (down).
• To avoid picking up unwanted low-frequency noise (rumble, thumps, etc.), it is advisable to roll off the low frequency response of mics other than those specifically for bass drum, bass guitar amp, upright bass or keyboard amps. For all other mics, set the Low Cut switches to the on position (up).
• Connect the balanced XLR (male) Output to the mic input on the mixer with a low-impedance mic cable.
• Connect headphones to the Phone/Aux jack. Alternatively this jack can be connected to the unbalanced input of an amplifier, another mixer, etc.
• Flip the Power switch to the ON position. The PWR (power) LED will illuminate.
• Adjust the Level controls for the desired mix and check the Clip LED to make sure one or more of them are not turned up too far. A small amount of Clip LED activity on occasional peaks is acceptable as it fires 3dB below the onset of actual clipping distortion.
• iAdjust the input gain of the other mixer for best signal strength without distortion.
