4. Operating Instructions

4.1 Channel Strip Controls

Each mono input channel features the following controls:

• Gain Control: Adjusts the input sensitivity for the microphone or line input. Set this to achieve a healthy signal level without clipping (indicated by the Peak LED).
• EQ (Equalizer): A 3-band EQ (High, Mid, Low) allows you to shape the tone of the input signal.
• AUX Sends: Controls the amount of signal sent to the auxiliary outputs, typically used for effects or monitor mixes.
• PAN: Positions the channel's signal within the stereo field (left to right).
• Mute/PFL: Mutes the channel or sends its signal to the PFL (Pre-Fader Listen) bus for monitoring through headphones.
• Channel Fader: Controls the overall level of the channel in the main mix.
• Peak LED: Illuminates when the signal level approaches clipping. Adjust the Gain control to prevent this LED from lighting consistently.

4.2 Master Section Controls

The master section provides overall control for the mixer:

• Main Mix Fader: Controls the overall output level of the stereo main mix.
• Headphone Level: Adjusts the volume for the headphone output.
• Aux Master Controls: Individual faders or knobs for controlling the overall level of each auxiliary send.
• Stereo Return: Controls the level of any stereo effects returns.

4.3 Phantom Power

The EPM6 provides +48V phantom power for condenser microphones. This is a global switch, meaning it applies to all mono XLR inputs simultaneously. Ensure dynamic microphones or ribbon microphones are not connected when phantom power is engaged, unless their specifications explicitly state compatibility.

5. Maintenance

5.1 Cleaning

To clean the mixer, use a soft, dry, lint-free cloth. Do not use liquid cleaners, abrasive cleaners, or solvents, as these can damage the finish and internal components. Regularly dust the surface and control knobs.

5.2 Storage

When not in use for extended periods, store the mixer in a cool, dry place, away from direct sunlight and extreme temperatures. It is recommended to use the original packaging for protection during storage or transport.
