6.2 Channel Controls

• GAIN: Adjusts the input sensitivity for each channel. Set this to achieve a strong signal without clipping (indicated by the PEAK LED).
• HIGH/MID/LOW (EQ): 3-band equalizer to shape the tone of each channel. Adjust these knobs to boost or cut high, mid, and low frequencies.
• AUX/EFF: Controls the amount of signal sent from the channel to the internal effects processor or an external auxiliary send.
• PAN: Pans the channel's signal between the left and right stereo outputs.
• LEVEL: Adjusts the output volume of the 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.

6.3 Main Section Controls

• MAIN Fader: Controls the overall output volume of the mixer.
• DELAY/EFF: Adjusts the level of the internal digital effects (e.g., delay, reverb) applied to the mix.
• TAPE/MP3: Controls the volume of the USB/Bluetooth media player input.
• PHONE: Adjusts the volume of the headphone output.
• REC: RCA outputs for connecting to a recording device.
• Level Meters: LED indicators showing the main output level. Aim for levels around 0dB to avoid distortion.

To connect a Bluetooth device:

1. Press the MODE button on the media player section until "Bluetooth" mode is selected. The Bluetooth indicator will flash.
