Operating Instructions
Microphone and Instrument Connection
- Microphones: Connect an XLR microphone to the MIC/LINE (Input 1) combo jack. For condenser microphones, activate +48V phantom power using the switch. The PHANTOM indicator will light up.
- Instruments: Connect a 1/4-inch TRS cable from your instrument (e.g., guitar, bass, keyboard) to Input 1 or Input 2. If connecting a guitar or bass to Input 1, ensure the HI-Z switch is engaged.
- Adjust the INPUT 1/GAIN knob to set the input level. The PEAK indicator should only flash occasionally during the loudest parts of your signal.
Monitoring Audio
- Connect your headphones to the PHONES output. Adjust the PHONES Level knob for comfortable listening.
- The MSc1 features direct monitoring. If you do not wish to hear your input signal directly through headphones (e.g., when monitoring through software), turn the PHONES level knob to its lowest setting.
- Use the MONO/STEREO button to switch between mono and stereo monitoring. If your input source is mono (e.g., a single microphone), ensure the button is unpressed for mono. If your input source is stereo, press the button for stereo monitoring.
Recording with a Computer
The Moukey MSc1 is compatible with most common Digital Audio Workstation (DAW) software on Mac OS X and Windows 7 or higher.
- After connecting the MSc1 to your computer, open your preferred DAW software.
- In your DAW's audio settings, select "USB AUDIO Device" (or similar) as your input and output device.
- Create a new audio track and arm it for recording.
- Adjust input gain on the MSc1 and monitor levels in your DAW to ensure a healthy signal without clipping.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power/device not recognized by computer. | Loose USB connection, faulty USB port, insufficient power from USB port. | Ensure USB cable is securely connected. Try a different USB port or cable. Restart your computer. Check device manager for "USB AUDIO Device". |
| No sound output from headphones/monitors. | Volume knobs turned down, incorrect output selected in software, incorrect cable connection. | Increase PHONES Level and OUTPUT knobs. Verify "USB AUDIO Device" is selected as output in your DAW/system settings. Check RCA/headphone cable connections. |
| No input signal/microphone not working. | Incorrect input selected, gain too low, +48V phantom power not enabled for condenser mic, faulty microphone/cable. | Ensure correct input is selected in your DAW. Increase INPUT 1/GAIN. Enable +48V for condenser mics. Test with a different microphone or cable. |
| High-pitched whistling/noise in recording. | Ground loop, interference, incorrect gain staging, faulty cable. | Ensure all equipment is properly grounded. Try different cables. Adjust gain levels to avoid clipping. Move device away from other electronics. |
| Direct monitoring cannot be disabled. | This is a hardware feature. | To avoid hearing the direct input signal, turn the PHONES level knob to its lowest setting. Software monitoring can still be used. |
