- Input Connections:
- Microphones: Connect microphones to the Mono inputs (25) using XLR cables. For condenser microphones, activate the +48V phantom power switch (2) on individual channels as needed, and the main +48V switch (13).
- Line-Level Devices (Mono): Connect instruments or other mono line-level sources to the Mono inputs (25) using 1/4" TRS cables.
- Stereo Devices: Connect stereo sources (e.g., keyboards, media players) to the Stereo inputs (26) using 1/4" TRS cables.
- Output Connections:
- Main Outputs: Connect your main speakers or power amplifier to the Main Out L/R (24) using XLR cables.
- Group Outputs: Use G1-G2 and G3-G4 outputs (24) for sub-mixes or routing to external processors.
- Auxiliary Outputs: Connect monitor speakers or external effects processors to the Auxiliary outputs (27).
- Headphones: Connect headphones to the Monitor jack (12) for personal monitoring.
- Initial Power On: Once all connections are secure, turn on the power switch (22) on the rear panel. The level display (11) should illuminate.
5. Operating Instructions
5.1. Channel Control
This image provides a close-up of the individual channel controls, including gain, EQ, aux sends, and pan.
- Gain Control (3): Adjusts the input sensitivity for each channel. Set this so the PEAK LED (10) flashes only occasionally during the loudest parts of the signal.
- Equalizer (5): Use the HIGH, MID, and LOW knobs to shape the tone of each channel.
- Aux Control (6): Sends a portion of the channel signal to the auxiliary outputs (27) for monitor mixes or external effects.
- Fx Control (7): Sends a portion of the channel signal to the internal DSP effects processor.
- Pan Control (8): Positions the channel signal within the stereo field (left to right).
- Mute Switch (9): Mutes the audio output of the individual channel.
- Peak/Solo Button (10): The PEAK LED indicates signal clipping. Pressing the SOLO button allows you to monitor the channel's signal independently through headphones (12).
5.2. DSP Effects

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | Power off; main faders down; mute engaged; incorrect input/output connections. | Check power, raise main faders (20), disengage mute (9), verify all cables are correctly connected. |
| Distorted sound | Input gain too high; output level too high; faulty cable. | Reduce input gain (3) and output levels (20, 21). Check PEAK LED (10). Try different cables. |
| Hum or noise | Ground loop; faulty cable; interference from other electronics. | Ensure all equipment is properly grounded. Try isolating the mixer from other electronics. Replace suspicious cables. |
| Bluetooth not connecting | Bluetooth not enabled on device; mixer not in pairing mode; device too far. | Ensure Bluetooth is active on your device. Select Bluetooth mode on the mixer. Keep devices within range. |

9. User Tips
- Gain Staging: Always set your input gain (3) correctly. Too low, and your signal will be noisy; too high, and it will distort. Aim for the PEAK LED (10) to flicker only on the loudest peaks.
- Phantom Power: Remember to only activate +48V phantom power (2, 13) for condenser microphones that require it. Dynamic microphones do not need phantom power and can be damaged if it's applied incorrectly.
- Cable Quality: Invest in good quality, shielded cables to minimize noise and ensure optimal signal transfer.
