5. Operating Instructions
5.1 Channel Controls
- GAIN: Adjusts the input sensitivity for each channel. Set this to achieve a strong signal without clipping (the PEAK LED should only flash occasionally).
- EQ (HIGH, MID, LOW): 3-band equalizer for shaping the tone of each channel.
Figure 5.1: Visual representation of the 3-band EQ frequency response curves. The HIGH band boosts/cuts above 12kHz, the MID band sweeps from 250Hz to 6kHz, and the LOW band boosts/cuts below 80Hz.
- HIGH: Adjusts frequencies above 12 kHz (±15 dB).
- MID: Adjusts frequencies between 150 Hz and 3.5 kHz (±15 dB). This is a sweepable mid-range control.
- LOW: Adjusts frequencies below 80 Hz (±15 dB).
- EFFECT: Sends a portion of the channel signal to the built-in effects processor.
- PAN: Adjusts the stereo position of the channel signal (left to right).
- CHANNEL FADER: Controls the output level of each individual channel to the main mix.
- PEAK LED: Illuminates when the input signal is too high, indicating potential clipping. Reduce the GAIN if this LED lights up frequently.
5.2 +48V Phantom Power
The mixer provides +48V phantom power for condenser microphones. To activate:
- Ensure all channel faders and the main fader are set to their minimum positions.
- Connect your condenser microphone(s) to the XLR inputs.
- Press the +48V PHANTOM POWER button. An indicator light will confirm activation.
- Gradually raise the channel faders and main fader to the desired levels.
Caution: Do not activate phantom power when dynamic microphones or other devices not requiring +48V are connected, as this may cause damage.
5.3 Bluetooth Connection

To connect a Bluetooth device:
- Press the "MODE" button on the MP3 player section until "Bluetooth" is selected on the digital display.
- On your mobile phone, tablet, or other Bluetooth-enabled device, search for available Bluetooth devices.
- Select "XTUGA MIXER" (or similar name) from the list to pair.
- Once paired, you can play audio from your device through the mixer.
5.4 USB/MP3 Playback and Recording
The mixer supports U-DISK MP3 playback and direct recording to a USB drive.
- MP3 Playback: Insert a USB flash drive containing MP3 files into the USB port. The mixer will automatically detect and begin playing the files. Use the control buttons (PLAY/PAUSE, PREV, NEXT) on the MP3 player section to navigate.
- Recording: To record the main mix to a USB drive, ensure a formatted USB drive is inserted. Press the "REC" button on the MP3 player section to start recording. Press it again to stop.
5.5 Digital Effects
The mixer includes a built-in digital effects processor. Use the "EFFECT" knob on each channel to send signal to the effects. The main "EFFECT" fader controls the overall level of the effects return to the main mix. Adjust the effect type and parameters using the dedicated controls in the effects section.
5.6 Monitoring
Connect headphones to the PHONES jack to monitor the main mix. The PHONES level knob controls the headphone volume. The main LED meters provide a visual indication of the main output level.

6. Maintenance
- Cleaning: Regularly wipe the mixer's surface with a soft, dry, lint-free cloth. Do not use abrasive cleaners, solvents, or waxes.
- Storage: When not in use for extended periods, store the mixer in a cool, dry place, away from direct sunlight and extreme temperatures. Cover the unit to protect it from dust.
- Cable Care: Avoid bending or twisting cables excessively. Disconnect cables by pulling the plug, not the cable itself.
