• AUX/FX Send: Controls the amount of signal sent to the internal effects processor or external auxiliary devices.
• PAN/VYVÁŽENÍ: Adjusts the stereo position of the channel's signal.
• Tlačítko MUTE: Ztlumí výstup kanálu.
• CLIP LED: Illuminates when the channel's signal is too high, indicating potential distortion. Reduce the GAIN if this LED lights up frequently.
• Fader LEVEL: Ovládá celkovou hlasitost kanálu v hlavním mixu.
