6. Operating Instructions
This section details how to operate the various functions of your audio mixer.
6.1 Basic Channel Operation
- Gain Adjustment: For each input channel, adjust the Gain Control knob until the PEAK LED flashes only occasionally during the loudest parts of the signal. This ensures optimal signal-to-noise ratio.
- Equalization (EQ): Use the HIGH, MID, and LOW knobs to shape the tone of each channel. Turn clockwise to boost frequencies, counter-clockwise to cut.
- Pan: Adjust the PAN knob to position the channel's sound in the stereo field (left to right).
- Channel Volume: Use the individual Channel Volume Faders to set the relative volume of each input.
- Main Mix: Adjust the Total Volume faders (L MAIN R) to control the overall output level of the mixer.
- 48V Phantom Power: If using condenser microphones, press the 48V PHANTOM POWER button. Ensure all condenser microphones are connected before activating.
6.2 Bluetooth & MP3 Player/Recorder
The mixer includes integrated Bluetooth and MP3 playback/recording capabilities.
- Bluetooth Connection: Activate Bluetooth on your smartphone or tablet. On the mixer's MP3 section, select Bluetooth mode. Pair with the device named 'BT-AUDIO' or similar. You can now stream audio wirelessly to the mixer.
- USB Playback: Insert a USB flash drive containing MP3 files into the USB slot. The mixer will automatically detect and begin playing audio. Use the MP3 Play Control buttons (Play/Pause, Next, Previous) to navigate tracks.
- USB Recording: The mixer can record the main mix directly to a USB flash drive. Select the recording function from the MP3 Play Control section and press record.
6.3 Digital Effects Processor
The mixer features a built-in digital effects processor, primarily offering delay effects. You can adjust the reverb depth and delay effect using the dedicated knobs.
- Applying Effects: Use the FX knob on each channel to send a portion of that channel's signal to the effects processor.
- Effect Level: Adjust the Effects Volume fader to control the overall level of the applied effect in the main mix.
- External Effects: The mixer also provides AUX Send and Return jacks for connecting external effects units.

8. Troubleshooting
If you encounter issues with your mixer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power cable disconnected; power outlet faulty; mixer power switch off. | Check power cable connection; try a different outlet; ensure power switch is ON. |
| No sound output | Main volume faders down; amplifier/speakers off or disconnected; incorrect input/output routing. | Raise main volume faders; check amplifier/speaker power and connections; verify correct cable routing. |
| No sound from a specific channel | Channel volume fader down; gain too low; input device faulty; 48V phantom power off for condenser mic. | Raise channel fader; increase gain; test input device; activate 48V phantom power if needed. |
| Distorted sound | Gain too high (PEAK LED constantly on); faulty cable; impedance mismatch. | Reduce gain until PEAK LED flashes only occasionally; try a different cable; ensure correct impedance. |
| Bluetooth not connecting | Mixer not in Bluetooth mode; device too far; interference. | Ensure mixer is in Bluetooth mode; bring device closer; minimize interference. |
If the problem persists after trying these solutions, please contact customer support.
