• AUX 1 PRE: Sends a portion of the channel signal to the AUX 1 output, independent of the channel fader. Typically used for monitor mixes.
• AUX 2 POST / FX: Sends a portion of the channel signal to the AUX 2 output and the internal effects processor, after the channel fader. Typically used for effects sends.
• PAN (canals mono) / BAL (canals estèreo): Adjusts the position of the channel signal within the stereo field (left to right).
