Guia de configuració

Segueix aquests passos per configurar el teu mesclador ARMX-4:

1. Connexió d'alimentació: Connect the provided power adapter to the DC IN port on the rear of the mixer and then to a suitable power outlet. Ensure the mixer's power switch is in the OFF position before connecting.
2. Microphone/Instrument Connection (Channels 1-2):
   • For microphones, connect an XLR cable to the MIC/LINE input.
   • For line-level instruments (e.g., keyboards, guitars with preamps), connect a 1/4" TS/TRS cable to the MIC/LINE input.
   • If using a condenser microphone, ensure the +48V PHANTOM power is switched ON (see Operating Instructions).
3. Stereo Input Connection (Channels 3/4): Connect stereo line-level devices (e.g., CD players, media players) using 1/4" TS/TRS cables to the L and R inputs of Channel 3/4.
4. Connexió de sortida principal: Connect the L and R STEREO OUT ports to your amplifier, powered speakers, or recording interface using 1/4" TS/TRS cables.
5. Connexió d'auriculars: Plug your headphones into the PHONES jack for monitoring.
6. External FX Connection (Optional): If using an external effects processor, connect the FX SEND output to the input of your external unit, and the output of your external unit back to an available LINE input on the mixer (e.g., Channel 3/4).
7. Connexió USB (opcional): Connect a USB cable from the "USB TO PC" port to your computer for audio streaming and recording.
8. Encès: Once all connections are made, switch the mixer's power to the ON position.

Instruccions de funcionament

1. Channel Controls (Channels 1-2)

• PAD Button (-26dB): Press to attenuate the input signal by 26dB for very loud sources.
• Botó HPF (80 Hz): Press to activate a High-Pass Filter at 80Hz, reducing low-frequency rumble.
• Mando GAIN: Adjusts the input sensitivity for the microphone or line input. Set this so the PEAK LED flashes only occasionally during the loudest parts of the signal.
• Equalitzador de 3 bandes (ALT, MIG, BAIX):
  • HIGH (10kHz): Ajusta les freqüències dels aguts.
  • MID (2.5kHz): Adjusts the mid-range frequencies.
  • LOW (100Hz): Ajusta les freqüències baixes.
  Turn clockwise to boost, counter-clockwise to cut. The center position is flat (no boost/cut).
• Botó FX: Controls the amount of signal sent from this channel to the internal DSP effects processor or external FX send.
• Control de nivell: Adjusts the overall volume of the channel in the main mix.
• LED PIC: S'il·lumina quan el senyal d'entrada és massa alt, cosa que indica un possible retall. Reduïu el GUANY si aquest LED s'il·lumina amb freqüència.

2. Channel Controls (Channels 3/4)

• Mando GAIN: Adjusts the input sensitivity for the stereo line input.
• Equalitzador de 3 bandes (ALT, MIG, BAIX): Same functionality as Channels 1-2.
• Botó FX: Controls the amount of signal sent from this channel to the internal DSP effects processor or external FX send.
• Control de nivell: Adjusts the overall volume of the channel in the main mix.

3. +48V Phantom Power

The +48V PHANTOM switch (located near the main meters) activates phantom power for the XLR inputs on Channels 1 and 2. This is required for condenser microphones. Ensure dynamic microphones are not connected when phantom power is engaged, as it could potentially damage them. Always connect microphones before activating phantom power, and deactivate it before disconnecting.

4. 16 DSP Effects

The ARMX-4 features a built-in digital effects processor with 16 presets. Use the PROGRAM knob to select an effect and the PARAMETER knob to adjust its specific parameters (e.g., delay time, reverb decay).

• PROGRAM Knob: Rotate to cycle through the 16 available effects. The selected effect number will be displayed on the digital screen.
• PARÀMETRE Knob: Adjusts a specific parameter of the selected effect.
• Botó de NIVELL D'EFECTES: Controls the overall volume of the applied effects in the main mix.
