• INPUT 1 / INPUT 2 (MIC/LINE): Combo jacks for connecting XLR microphones or 1/4-inch line/instrument cables.
• +48V PHANTOM (CH1-2): Red button to activate +48V phantom power for condenser microphones on both channels. An indicator LED illuminates when active.
• HI-Z: Switch for input 2 to optimize impedance for high-impedance instruments like electric guitars.
• LEVEL 1 / LEVEL 2: Rotary knobs to adjust the input gain for Channel 1 and Channel 2, respectively.
• ST PAN / 2R: Switch for Channel 2. In ST PAN mode, Channel 2 is panned to the right. In 2R mode, Channel 2 is routed to the right output.
• REC (MIC / MIC+PC): Switch to select the recording source for the USB output. MIC records only the mixer inputs. MIC+PC records mixer inputs mixed with audio from the computer.
• HUVUDSAK: Rotary knob to control the overall output level to the MAIN OUTPUTS.
• TELEFON: Rotary knob to control the volume of the headphone output.
• MAIN OUTPUTS (1/L, 2/R): 1/4-inch TRS jacks for connecting to studio monitors or other amplifieringssystem.
• USB-port (bak): Connects the mixer to a computer for audio interface functionality and bus power.
• POWER Switch (Rear): Selects between PC (USB bus power) and DC (external power, adapter not included).

Inställning

1. Ansluta till en dator

1. Ensure the MXU2's rear POWER switch is set to PC.
2. Connect the provided USB cable from the MXU2's USB port to an available USB port on your computer.
3. The mixer is typically plug-and-play, requiring no special drivers for most operating systems (Windows, macOS). Your computer should automatically recognize it as an audio device.
4. Select the MXU2 as your input/output audio device in your computer's sound settings and your Digital Audio Workstation (DAW) or recording software.

2. Connecting Microphones and Instruments

1. Mikrofoner: Connect XLR microphones to the INPUT 1 or INPUT 2 combo jacks using XLR cables. For condenser microphones, press the +48V FANTOM button. The red LED will illuminate. Caution: Do not activate phantom power for dynamic microphones or ribbon microphones unless specified by the manufacturer, as it may cause damage.
2. Instrument/Linjenivåenheter: Connect instruments (e.g., guitar, bass) or line-level devices (e.g., keyboard, drum machine) to the INPUT 1 or INPUT 2 combo jacks using 1/4-inch TRS or TS cables. For high-impedance instruments like electric guitars, engage the HI-Z switch for Input 2.

3. Anslutning av utmatningsenheter

1. Studiomonitorer/högtalare: Connect your studio monitors or powered speakers to the MAIN OUTPUTS (1/L, 2/R) using 1/4-inch TRS cables.
2. Hörlurar: Plug your headphones into the 1/4-inch PHONES jack.

Drift

1. Justering av ingångsnivå

1. Before playing or speaking, turn the NIVÅ 1 och NIVÅ 2 knobs fully counter-clockwise.
2. Begin playing your instrument or speaking into the microphone. Slowly turn the corresponding LEVEL knob clockwise until the SIG (signal) LED illuminates consistently.
3. Adjust the level so that the PEAK LED only flashes occasionally during the loudest parts of your performance. If the PEAK LED stays lit, the signal is clipping, and you should reduce the input level.

2. Huvudutgång och övervakning

1. Justera HUVUDSAK knob to control the overall volume sent to your studio monitors or speakers.
2. Använd TELEFON knob to set a comfortable listening volume for your headphones.

3. Recording Modes (REC Switch)

• MIC: In this mode, only the audio from the mixer's inputs (microphones/instruments) is sent to your computer via USB. This is ideal for recording new tracks.
• MIC+PC: This mode mixes the audio from the mixer's inputs with the audio playback from your computer. This is useful for monitoring your performance along with backing tracks or previously recorded material.

4. Stereo Panning (ST PAN / 2R Switch)

• De ST PAN / 2R switch affects how Input 2 is routed. In ST PAN mode, Input 2 is panned to the right channel of the stereo output. In 2R mode, Input 2 is routed directly to the right output, bypassing the pan control.

• Undvik att tappa eller utsätta mixern för hårda stötar.
• Do not attempt to disassemble or modify the unit, as this will void the warranty.
• Säkerställ ordentlig ventilation runt enheten under drift.

Felsökning

No Power / Device Not Recognized

• Kontrollera USB-anslutning: Ensure the USB cable is securely connected to both the mixer and the computer. Try a different USB port on your computer.
• Power Switch Setting: Verify the rear POWER switch is set to PC for bus power. If using an external DC adapter (not included), ensure the switch is set to DC and the adapter is functioning.
• Kabelintegritet: Testa en annan USB-kabel för att utesluta att kabeln är trasig.
• Datorigenkänning: Check your computer's Device Manager (Windows) or System Information (macOS) to see if the MXU2 is listed as an audio device. Restart your computer if necessary.

Ingen ljudutgång

• Nivåknappar: Säkerställa NIVÅ 1, NIVÅ 2, HUVUDSAK, och TELEFON knobs are turned up sufficiently.
• Utgångsanslutningar: Verify that your studio monitors/speakers are properly connected to the HUVUDUTGÅNGAR and are powered on. Check headphone connection.
• Computer Audio Settings: Confirm that the MXU2 is selected as the output device in your computer's sound settings and your recording software.
• REC Switch: If you expect to hear computer audio, ensure the REC omkopplaren är inställd på MIC+PC.

Förvrängt ljud / Klippning

• Ingångsnivåer: Minska NIVÅ 1 or NIVÅ 2 knobs if the PEAK LED is constantly lit.
• Utdatanivåer: Se till att HUVUDSAK och TELEFON levels are not set too high, causing distortion in connected speakers or headphones.
• Kabelkvalitet: Use high-quality, shielded cables to minimize interference.

Fantomkraftsproblem

• Aktivering: Se till att +48V FANTOM button is pressed and its LED is illuminated when using condenser microphones.
• Mikrofonkompatibilitet: Confirm your microphone requires phantom power.
