Frequently Asked Questions - EM-312 Omnitronic
How do I connect a microphone to the EM-312?
Use channel 1 or 2 with an XLR cable. Ensure phantom power is on if using a condenser mic. Adjust gain using the GAIN knob.
Why is there no sound from the speakers?
Check that the mixer is powered on and the MAIN VOLUME is up. Ensure all cables are firmly connected. Verify that the channel MUTE button is not engaged.
Can I use the EM-312 for recording?
Yes, connect the REC OUT (RCA) to your audio interface or recorder. The main mix is sent to this output.
How do I clean the mixer?
Disconnect power. Wipe the surface with a soft, dry cloth. Do not use alcohol or chemical cleaners as they may damage the finish.
What does the <b>+48V</b> switch do?
It provides phantom power for condenser microphones. Leave it OFF for dynamic mics to avoid damage.
How do I connect external effects?
The EM-312 does not have dedicated send/return jacks. You can use an external effects processor inline with the signal path.
What power supply does the EM-312 need?
It uses a 12V DC adapter with center positive polarity. Use only the supplied adapter to avoid damage.
Can I use both microphone and line inputs simultaneously?
Yes, each channel has a combo jack. You can connect a mic and a line source to different channels and mix them.
How do I adjust the headphone volume?
Use the PHONES knob on the front panel. Ensure the headphone jack is fully inserted.
Why does the sound distort?
Reduce the channel GAIN or MAIN VOLUME. Distortion may occur if the input signal is too high or the EQ is boosted excessively.
