4. Operasyon
4.1 Giriş Seviyesi Ayarlaması
Adjust input levels to prevent clipping and ensure optimal recording quality.
- MIC (Phantom Power): For condenser microphones, press the PHANTOM POWER switch to ON. Adjust the MIC gain knob for the desired input level. The SIG/OL (Signal/Overload) indicator will light green for signal presence and red for overload. Aim for green, avoiding red.
- LINE/GUITAR: Adjust the LINE gain knob for line-level instruments or guitars. The SIG/OL indicator functions similarly.
4.2 İzleme
The US-122MKII offers zero-latency monitoring, allowing you to hear your input signal directly without delay from the computer.
- MON MIX Knob: This knob blends the direct input signal (INPUT) with the playback signal from your computer (COMPUTER). Turn towards INPUT to hear more of your live input, and towards COMPUTER to hear more of your DAW's playback.
- PHONES/LINE OUT Knob: This controls the overall output level for both the headphone jack and the RCA line outputs.
- MONO Switch: When engaged, this switch sums the stereo input signal to mono for monitoring.
4.3 MIDI İşlemi
The MIDI IN and OUT ports allow communication with MIDI-compatible devices.
- Connect your MIDI controller's MIDI OUT to the US-122MKII's MIDI IN.
- Connect the US-122MKII's MIDI OUT to your MIDI device's MIDI IN.
- Ensure your DAW software is configured to recognize the US-122MKII's MIDI ports.

| No sound from outputs/headphones. | Output level too low; incorrect output routing in DAW; cable issues. | Increase PHONES/LINE OUT knob. Verify output routing in DAW. Check cable connections. |
| Distortion or crackling audio. | Input level too high (clipping); incorrect sample rate/buffer size; USB cable issue; driver instability. | Reduce input gain to avoid SIG/OL indicator turning red. Adjust buffer size in DAW settings. Try a different USB port/cable. Update or reinstall drivers. Unplug and replug the unit. |
| High latency during recording. | Buffer size too high in DAW; computer performance issues. | Reduce buffer size in your DAW's audio settings. Close unnecessary applications. Ensure your computer meets system requirements. Utilize zero-latency monitoring. |
| MIDI not working. | Incorrect MIDI connections; DAW not recognizing MIDI device; MIDI channel mismatch. | Verify MIDI IN/OUT connections. Check DAW MIDI device settings. Ensure MIDI channels match between devices and DAW. |
