6. Operating Instructions

6.1 Powering On/Off

Always ensure all volume controls are at their minimum before powering on the mixer. Power on the mixer first, then your amplifiers/active speakers. When powering off, reverse the order: turn off amplifiers/active speakers first, then the mixer.

6.2 Adjusting Input Gain and EQ

• Gain (3): Use the Gain knob to set the input level for each channel. Adjust it so that the peak indicator light (if present) flashes only occasionally during the loudest parts of the signal.
• Equalizer (4): Use the High, Mid, and Low EQ knobs to shape the tone of each input.

6.3 Using Phantom Power and Mute

• +48V Phantom Power (1): Press this button to supply +48V power to condenser microphones connected to the corresponding channel. Ensure the microphone is compatible before activating.
• Mute Button (2): Press the Mute button to silence the corresponding channel. This is useful for temporarily cutting off a signal without changing its fader position.

6.4 DSP Effects
