CONNECTION  
OPERATION  
Connect microphones to the MX34c via balanced XLR cables.  
Stereo auxiliary sources such as the output from another mixer, AM/FM tuners,  
CD Players, and MP3 players may be connected to the AUX IN via a stereo 1/8”  
(3.5mm) Tip-Ring-Sleeve plug.  
Connect the STEREO OUT to the Input of your recording device also using a  
stereo 1/8” (3.5mm) Tip-Ring-Sleeve plug.  
Once your MX34c is properly connected, apply power by pressing in the POWER  
button on the rear panel. The blue pwr LED on the front panel should light.  
If you are using condenser type microphones, apply the phantom power to the  
desired channels. Test the microphone levels by speaking into the microphones  
at a normal operating volume, and adjust the Mic Level controls until you achieve  
desired levels. Adjust each Pan control to place the signal in the stereo eld.  
If you wish to use AC power for the MX34c, connect the Rolls PS27 12VDC  
power supply.  
Adjust the Headphone Level control for a comfortable listening volume.
