4. Einrichtung
4.1 Systemanforderungen
- Operating System: Windows (compatible with most modern Windows versions).
- Verfügbarer USB-Anschluss.
- Persönlicher Computer.
4.2 Connecting the AI-22
- Mit Computer verbinden: Use the provided Micro USB cable to connect the AI-22 to an available USB port on your computer. The POWER indicator on the front panel will illuminate.
- Treiber installieren (falls erforderlich): The AI-22 is typically a class-compliant USB audio device, meaning it should work with standard drivers built into your operating system. If your computer does not automatically recognize the device or if you experience issues, please visit the official Ahuja website for specific driver downloads or troubleshooting guides.
- Mikrofone/Instrumente anschließen:
- For microphones, connect via the XLR input of the MIC/LINE jacks. If using a condenser microphone, activate +48V phantom power (refer to Section 5.2).
- For line-level sources (e.g., mixer output), connect via the TRS input of the MIC/LINE jacks.
- For instruments (e.g., guitar, bass), connect via the INST jacks.
- Ausgabegeräte anschließen:
- For monitor speakers, connect from the rear panel outputs (not explicitly shown in images, but implied by 'OUTPUT' knob).
- For headphones, connect to the 1/4-inch TRS Headphone Output on the front panel.
5. Bedienungsanleitung
5.1 Eingangsverstärkungseinstellung
- Adjust the gain knob for each input (MIC/LINE, INST) until the SIG indicator lights up consistently during signal presence.
- Ensure the CLIP indicator does not light up, as this indicates signal distortion. If it does, reduce the gain.
5.2 Phantomspeisung (+48 V)
- If using a condenser microphone, press the +48V button to supply phantom power. The +48V indicator will illuminate.
- Do not activate +48V for dynamic microphones or ribbon microphones unless specifically required and supported by the microphone, as it can cause damage.
5.3 Direkte Überwachung
- Press the DIRECT MONITOR button to enable zero-latency monitoring of your input signals. This allows you to hear your performance without delay, which is crucial during recording.
- When direct monitoring is active, the input signal is routed directly to the outputs (headphones and main outputs) before being processed by the computer.
5.4 Ausgangspegelregelung
- Use the OUTPUT knob to adjust the overall listening volume for your monitor speakers and headphones.

7. Fehlerbehebung
If you encounter issues with your AI-22, refer to the following common problems and solutions:
| Problem | Mögliche Ursache | Lösung |
|---|---|---|
| Kein Strom (Betriebs-LED aus) | USB cable not connected or faulty; computer USB port issue. | Ensure USB cable is securely connected to both the AI-22 and the computer. Try a different USB port or cable. |
| No input signal (SIG LED off) | Microphone/instrument not connected; gain too low; incorrect input selected in software. | Check cable connections. Increase input gain. Verify input selection in your recording software. |
| Distorted input signal (CLIP LED on) | Eingangsverstärkung zu hoch. | Reduce the input gain until the CLIP LED no longer illuminates. |
| Kein Ausgabeton | Output volume too low; incorrect output device selected in computer settings; faulty cables/speakers/headphones. | Increase the OUTPUT knob. Check your computer's sound settings to ensure the AI-22 is selected as the output device. Test with different cables or output devices. |
| Latenz während der Überwachung | Direct monitoring not enabled; software latency. | Press the DIRECT MONITOR button. Adjust buffer size settings in your recording software to reduce latency. |
