5. Configuració

Follow these steps to set up your Mini300 ampmés viu:

1. Connectar els altaveus: Connect your passive speakers to the "R Out" (Right) and "L Out" (Left) terminals on the rear panel. Ensure correct polarity: positive (+) terminal on the amplifier to the positive (+) terminal on the speaker, and negative (-) to negative (-).
2. Connecta la font d'àudio:
   • Per Entrada equilibrada: Connect your audio source (e.g., DAC, preamplifier) to the IN2 (TRS) inputs using balanced TRS cables.
   • Per Entrada d'un sol extrem: Connect your audio source to the IN1 (RCA) inputs using RCA cables.

   Nota: Only one input type (Balanced or Single-Ended) can be active at a time. Select the desired input using the switch on the front panel.
3. Connect 12V Trigger (Optional): If your source device has a 12V trigger output, connect it to the "12V TRIGGER IN" port on the Mini300. Set the TRIG switch on the front panel to "ON" for synchronized power control.
4. Connectar l'alimentació: Connect the supplied power adapter to the "DC 38V" input on the rear panel, then plug the adapter into a suitable AC power outlet.
5. Configuració inicial del volum: Before powering on, turn the volume knob on the front panel to its minimum position (fully counter-clockwise).

6. Funcionament

Once the setup is complete, follow these steps to operate your Mini300 ampmés viu:

1. Encès:
   • If the TRIG switch is OFF: The amplifier will power on automatically when the power adapter is connected to the mains.
   • If the TRIG switch is ON: The amplifier will power on when it receives a 12V trigger signal from the connected source device.

   The power indicator on the front panel will illuminate when the unit is powered on.

2. Seleccioneu l'entrada: Use the "BAL/SE" switch on the front panel to select between the Balanced (TRS) or Single-Ended (RCA) input, corresponding to your connected audio source.
3. Ajustar el volum: Start playing audio from your source. Slowly rotate the volume knob clockwise to increase the volume to a comfortable listening level. Avoid setting the volume too high to prevent hearing damage or speaker damage.
4. Apagar:
   • If the TRIG switch is OFF: Disconnect the power adapter from the mains to power off the ampmés viu.
   • If the TRIG switch is ON: The amplifier will power off automatically when the 12V trigger signal from the source device is removed.
