- හෙඩ්ෆෝන් ප්රතිදානය: 1/4-inch TRS jack for connecting headphones.
4. පිහිටුවීම
4.1 පද්ධති අවශ්යතා
- Operating System: Windows (compatible with most modern Windows versions).
- ලබා ගත හැකි USB පෝට් එක.
- පුද්ගලික පරිගණකය.
4.2 Connecting the AI-22
- පරිගණකයට සම්බන්ධ කරන්න: 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.
- ධාවක ස්ථාපනය කරන්න (අවශ්ය නම්): 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.
- මයික්රෆෝන/උපකරණ සම්බන්ධ කරන්න:
- 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.
- ප්රතිදාන උපාංග සම්බන්ධ කරන්න:
- 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. මෙහෙයුම් උපදෙස්
5.1 Input Gain Adjustment
- 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 ෆැන්ටම් පවර් (+48V)
- 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 සෘජු අධීක්ෂණය
- 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 Output Level Control
- Use the OUTPUT knob to adjust the overall listening volume for your monitor speakers and headphones.
5.5 Common Usage Scenarios
