Operating Instructions

This section details how to operate the various functions of your Depusheng DA8 mixer.

Powering On and Basic Audio Routing

1. After all connections are made, turn on the mixer using the Power Switch on the rear panel.
2. Ensure all channel volume faders and the main L/R fader are at their lowest position before playing audio.
3. For each active input channel, slowly increase the Gain Adjustment Knob until the Peak Signal Indicator occasionally flashes, then back off slightly. This sets the optimal input level.
4. Slowly raise the individual channel's Volume Fader to bring the sound into the mix.
5. Gradually raise the L MAIN R fader to control the overall output volume.
6. Adjust the Headphone Volume Control to monitor the mix through your headphones. Use the Monitor Button (PFL/AFL) on individual channels to solo and listen to specific inputs before they reach the main mix.

Equalization (EQ)

Each channel features a 3-band EQ (High, Mid, Low) to shape the tone of your audio. Adjust these knobs to enhance or cut specific frequencies.

• HF (High Frequency): Controls the brightness and clarity of the sound. Turn clockwise to boost, counter-clockwise to cut.
• MF (Mid Frequency): Affects the presence and body of vocals and instruments.
• LF (Low Frequency): Manages the bass and warmth of the sound.
