Фигура 1: Отгоре надолу view of the CAD Audio MXU2 mixer, showing all controls and inputs/outputs.

• 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.
• ОСНОВЕН: Rotary knob to control the overall output level to the MAIN OUTPUTS.
• ТЕЛЕФОНИ: 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 ampлификационни системи.
• USB Port (Rear): 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).

Настройка

1. Свързване към компютър

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. Свързване на микрофони и инструменти

1. Микрофони: Connect XLR microphones to the INPUT 1 or INPUT 2 combo jacks using XLR cables. For condenser microphones, press the +48V ФАНТОМ 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. Инструменти/Устройства на линейно ниво: 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 ЗДРАВЕЙ-З switch for Input 2.

3. Свързване на изходни устройства

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

Оперативен

1. Input Level Adjustment

1. Before playing or speaking, turn the НИВО 1 и НИВО 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. Main Output and Monitoring

1. Коригирайте ОСНОВЕН knob to control the overall volume sent to your studio monitors or speakers.
2. Използвайте ТЕЛЕФОНИ knob to set a comfortable listening volume for your headphones.

3. Recording Modes (REC Switch)

• микрофон: 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)

• The 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.

Отстраняване на неизправности

No Power / Device Not Recognized

• Проверете USB връзката: 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.
• Цялост на кабела: Опитайте с друг USB кабел, за да изключите евентуална повреда.
• Компютърно разпознаване: 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.

Няма изход на звук

• Level Knobs: Осигурете НИВО 1, НИВО 2, ОСНОВЕН, и ТЕЛЕФОНИ knobs are turned up sufficiently.
• Изходни връзки: Verify that your studio monitors/speakers are properly connected to the ОСНОВНИ ИЗХОДИ 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 превключвателят е настроен на MIC+PC.

Изкривен звук / Изрязване

• Входни нива: Намалете НИВО 1 or НИВО 2 knobs if the PEAK LED is constantly lit.
• Изходни нива: Осигурете ОСНОВЕН и ТЕЛЕФОНИ levels are not set too high, causing distortion in connected speakers or headphones.
• Качество на кабела: Use high-quality, shielded cables to minimize interference.

Проблеми с фантомното захранване

• Активиране: Осигурете +48V ФАНТОМ button is pressed and its LED is illuminated when using condenser microphones.
