This image provides a comprehensive look at the user interface, including input gains, EQ sections, auxiliary sends, pan controls, channel faders, the effects processor, and the main mix controls.

The mixer's top panel (Figure 4.1) is divided into several sections:

• Canali di ingresso: Channels 1-4 feature XLR microphone inputs and 1/4" line inputs. Channels 5/6, 7/8, 9/10, and 11/12 are stereo line inputs.
• Sezione EQ: Each mono channel (1-4) includes a 3-band equalizer (HIGH, MID, LOW).
• Invii ausiliari: Two auxiliary sends (AUX 1 PRE, AUX 2 POST) per channel for monitoring or external effects.
• Effects Processor (PROFX): A dedicated section with 256 digital effects, including reverbs, delays, and chorus.
• Sezione Master: Controls for the main mix output, control room output, headphone output, and level meters.

5.1 Collegamento di alimentazione

1. Ensure the mixer's power switch (Figure 5.1) is in the OFF position.
2. Connect the supplied power adapter to the 18V DC input on the rear panel of the mixer.
3. Collegare l'adattatore di alimentazione a una presa di corrente CA adatta.
4. Turn the power switch to the ON position. The power indicator LED on the front panel should illuminate.

5.2 Connessioni di ingresso audio

• Microfoni (canali 1-4): Connect microphones using balanced XLR-F cables to the MIC inputs. If using condenser microphones, activate the +48V Phantom Power switch located in the master section.
• Ingressi di linea (canali 1-4): Connect line-level instruments or devices (e.g., keyboards, guitars with preamps) using balanced 1/4" JACK cables to the LINE inputs.
• Ingressi di linea stereo (canali 5/6, 7/8, 9/10, 11/12): Connect stereo line-level sources (e.g., media players, synthesizers) using 1/4" JACK cables. Use both LEFT and RIGHT inputs for stereo, or only the LEFT input for mono operation.

5.3 Connessioni di uscita audio

• Main Mix Output: Connect the MAIN MIX LEFT and RIGHT outputs (1/4" JACK) to your power amplificatore, altoparlanti amplificati o dispositivi di registrazione.
• Uscita della sala di controllo: Connect C.ROOM LEFT and RIGHT outputs (1/4" JACK) to your studio monitors.
• Uscita cuffie: Connect your headphones to the PHONES output (1/4" JACK).

6. Istruzioni per l'uso

6.1 Canali di ingresso (1-12)

• GUADAGNO: Adjusts the input sensitivity for the connected microphone or line source. Set this so the PEAK LED flashes only occasionally during the loudest parts of the signal.
• LO CUT (Channels 1-4): Activates a 75 Hz high-pass filter to remove unwanted low-frequency rumble.
• EQ (HIGH, MID, LOW - Channels 1-4): These knobs adjust the treble (12 kHz), midrange (2.5 kHz), and bass (80 Hz) frequencies of the input signal. Use them to shape the tone of your instrument or vocal.
• 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 (canali mono) / BAL (canali stereo): Adjusts the position of the channel signal within the stereo field (left to right).
• LED DI PICCO: Si accende quando il segnale di ingresso è troppo alto, indicando un potenziale clipping. Ridurre il GAIN se questo LED si accende frequentemente.
• Channel Fader/Level: Controlla il volume complessivo del canale inviato al mix principale.

6.2 Effects Processor (PROFX)

The Mi12 features a digital effects processor with 256 effects (16 presets x 16 variations).

• PRESET: Turn this knob to select one of the 16 effect types (e.g., Hall, Room, Vocal, Plate Reverbs, Delays, Chorus).
• VARIAZIONE: Turn this knob to select one of the 16 variations for the chosen effect preset.
• FX TO AUX 1: Controls the amount of the effect signal sent to the AUX 1 output.
• FX AL PRINCIPALE: Controls the amount of the effect signal sent to the main stereo mix.
• RUBINETTO: Press this button to set the tempo for delay effects.

6.3 Sezione Master

• Fader MIX PRINCIPALE: Controlla il volume di uscita complessivo del mix stereo principale.
• MAIN MIX Meters: LED meters display the output level of the main mix. Aim for levels around 0 dB during normal operation, avoiding consistent red (clip) indications.
• C.ROOM / PHONES Level: Adjusts the volume for the Control Room outputs and the Headphone output.
• FANTASMA ON/OFF: Activates or deactivates +48V phantom power for condenser microphones connected to XLR inputs. Ensure this is OFF before connecting/disconnecting microphones.

7. Manutenzione

• Pulizia: Disconnect the mixer from power before cleaning. Use a soft, dry cloth to wipe the surface. Do not use liquid cleaners or solvents.
• Magazzinaggio: Quando non viene utilizzato per lunghi periodi, conservare il mixer in un luogo fresco e asciutto, lontano dalla luce solare diretta e da temperature estreme.
• Protezione dalla polvere: Cover the mixer with a dust cover when not in use to prevent dust accumulation on controls and connectors.

8. Risoluzione Dei Problemi

• Nessuna uscita audio:
  • Check all power connections and ensure the mixer is turned ON.
  • Verify that the MAIN MIX fader is up and not muted.
  • Check individual channel faders and GAIN controls.
  • Ensure output cables are correctly connected to your amplifier/speakers and that they are powered on.
• Suono distorto:
  • Ridurre il controllo GAIN sul canale di ingresso se il LED PEAK è costantemente acceso.
  • Lower the channel fader or MAIN MIX fader if the main meters are consistently in the red.
  • Controllare che non vi siano cavi o collegamenti difettosi.
• Effetti non funzionanti:
  • Ensure the AUX 2 POST / FX knob on the desired channel is turned up.
  • Check the FX TO MAIN knob in the effects section.
  • Verify that an effect preset and variation are selected.
