• For Condenser Microphones: If using a condenser microphone, ensure it is connected, then activate the +48V power switch (21). The indicator light will illuminate.
• For Dynamic Microphones/Instruments: Connect directly to the MIC/LINE inputs. No phantom power is needed.

Operating Instructions

1. Adjusting Input Levels (Gain)

Use the GAIN knob (2) for each channel to set the input level. Adjust it so that the PEAK indicator light for that channel flashes only occasionally during the loudest parts of your audio. Avoid constant illumination of the PEAK light, as this indicates clipping and distortion.

2. Equalization (EQ)

Each channel has HF (3) and LF (4) knobs for basic high and low frequency adjustments. The main output features a 5-band Graphic Equalizer (16) to fine-tune the overall sound. Adjust the sliders to boost or cut specific frequency ranges (70Hz, 200Hz, 1KHz, 5KHz, 12KHz) for the main mix.

3. DSP Effects

The mixer includes 99 built-in DSP effects. Use the 99 Effects selection knob (8) to scroll through the available effects (e.g., Reverb, Delay, Chorus). The selected effect number will appear on the display (9). Adjust the effect parameters using the 99 Effects adjustment knobs (10) and the overall effect send level for each channel with the FX knob (5). The master effect volume is controlled by the Effect volume knob (17).

4. Vocal Removal

To remove vocals from a track playing via USB or Bluetooth, press the Mp3 VC button (13). This feature attempts to isolate and reduce the vocal track, leaving an instrumental version. The effectiveness may vary depending on the original audio source.

5. USB Playback

Insert a USB flash drive containing MP3 audio files into the USB port (20). The mixer will automatically detect and begin playing the files. Use the Mp3 adjustment knobs (11) and Mp3 REP (12) to control playback (play/pause, skip tracks, repeat). Adjust the overall USB playback volume with the Mp3 total volume knob (18).

6. Bluetooth Connectivity

After pairing your device (as described in Setup), ensure the mixer is in Bluetooth mode (display shows 'BT'). You can now stream audio wirelessly from your smartphone, tablet, or computer to the mixer. Control playback and volume from your connected device or using the mixer's MP3 controls.

7. Live Streaming

Connect your mobile phone or computer to the mixer via USB (TYPE-C/USB port 20). The mixer acts as an audio interface, sending the mixed audio directly to your streaming software or application. This plug-and-play functionality simplifies your live broadcast setup.
