4. Configurazione e connessioni

Before powering on the mixer, ensure all connections are made correctly.

4.1 Collegamento di alimentazione

1. Connect the supplied power adapter to the mixer's power input.
2. Plug the power adapter into a suitable AC outlet. Ensure the mixer's power switch is in the OFF position before connecting.

• EQ (ALTO, MEDIO, BASSO): Three-band equalizer for shaping the tone of the input signal.
• AUX 1 (PRE): Sends signal to Aux Send 1, independent of the channel fader, ideal for monitor mixes.
• AUX 2 (POST): Sends signal to Aux Send 2, dependent on the channel fader, typically used for effects.
• PADELLA: Posiziona il segnale del canale nel campo stereo (da sinistra a destra).
• MUTO: Disattiva il canale.
• MAIN MIX/SUB: Routes the channel to the main stereo mix or to the selected subgroup.
• LEVEL FADER: Controlla il volume generale del canale.

5.2 Stereo Channel Controls (Channels 5/6 - 11/12)

• Similar controls to mono channels, but often with simplified EQ and input options for stereo sources.
• BILANCIA: Adjusts the relative level between the left and right stereo inputs.

5.3 Controlli della sezione master

• FADER MIX PRINCIPALI: Controlla il livello di uscita complessivo del mix stereo principale.
• AUX SENDS MASTERS: Control the overall level of Aux Send 1 and Aux Send 2.
• AUX RETURNS: Adjust the level of signals returning from external effects processors.
• PHONES/CONTROL ROOM: Controls the volume for headphones and control room outputs.
• MISURATORI DI LIVELLO: Provide visual indication of signal levels. Aim for levels around 0 dB to avoid clipping.
