5. Setup u Konnessjoni

5.1 Passive Mode Setup

In passive mode, the MC5-BX does not require external power. It functions as a purely mechanical mixer, combining input signals. This mode is suitable for situations where signal amplification is not needed or when connecting to devices with their own amplifikazzjoni.

1. Ensure the Active/Passive Mode Switch is set to PASSA.
2. Connect your audio sources (e.g., phone, Xbox, computer, CD player) to the IN-1 permezz IN-4 3.5mm AUX input jacks.
3. Connect your output device (e.g., headphone amplifier, amplifier, mixer) to the BARRA 3.5mm AUX output jack.
4. Adjust the individual input volume knobs and the master output volume knob as desired.

5.2 Active Mode Setup

Active mode requires external DC 5V power via the Type-C USB port. In this mode, the mixer provides signal buffering and potentially a slight gain, offering a more robust output signal and better isolation between inputs.

1. Ensure the Active/Passive Mode Switch is set to IC.
2. Connect a DC 5V (0.5A) power adapter (not included) to the DC 5V IN Type-C USB port. Use an independent power supply for the mixer.
3. Connect your audio sources (e.g., phone, Xbox, computer, CD player) to the IN-1 permezz IN-4 3.5mm AUX input jacks.
4. Connect your output device (e.g., headphone, amplifier, mixer) to the BARRA 3.5mm AUX output jack.
5. Turn on the mixer using the Power ON/OFF switch. The power indicator LED will illuminate.
6. Adjust the individual input volume knobs and the master output volume knob as desired.

2. Power On (Active Mode Only): If in active mode, press the ON/OFF switch to power on the unit. The power indicator will light up.
3. Adjust Input Volumes: Rotate the individual input volume knobs (IN-1 to IN-4) clockwise to increase the volume of each respective audio source, and counter-clockwise to decrease it.
4. Aġġusta l-Volum tal-Ħruġ: Rotate the master output volume knob (VOL) clockwise to increase the overall mixed output volume, and counter-clockwise to decrease it.
5. Monitoraġġ: Listen to the mixed audio through your connected output device and fine-tune the volume levels for a balanced sound.
