7. Operating the Mixer
Once your mixer is set up, you can begin mixing and recording audio:
7.1 Adjusting Input Levels
- Set all 'LEVEL' knobs to their minimum position.
- Speak into the microphone or play your instrument at its typical volume.
- Slowly increase the 'GAIN' knob for the microphone channel until the corresponding level meter shows a strong signal, ideally peaking in the yellow range without consistently hitting red (clipping).
- Adjust the 'LEVEL' knobs for other input channels similarly.
7.2 Using the Compressor

The 'COMP' knob on the microphone channel provides simple, effective compression. Turn the knob clockwise to increase the compression amount. The adjacent LED will illuminate to indicate when compression is active. Compression helps to smooth out dynamic peaks and valleys in your audio, making it sound more consistent.
7.3 Applying EQ

Use the 'EQ' (High and Low) knobs to shape the tone of your microphone signal. Turn the 'HIGH' knob clockwise to boost treble frequencies or counter-clockwise to cut them. Similarly, use the 'LOW' knob to boost or cut bass frequencies. Experiment to find the desired sound.
7.4 Monitoring Audio
- Adjust the 'PHONES' knob to control the volume of your headphones.
- The '2-TR/USB' button allows you to route the USB audio playback to either the main mix or the phones/control room output.
7.5 Recording via USB

Once connected to your computer, the XENYX Q502USB will be recognized as an audio interface. You can then select it as your input and output device in your digital audio workstation (DAW) software or other recording applications. The main mix output of the mixer will be sent to your computer for recording.

8. Maintenance
To ensure the longevity and optimal performance of your mixer:
- Keep the unit clean by wiping it with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Protect the mixer from dust, moisture, and extreme temperatures.
- Avoid placing heavy objects on the mixer.
- Ensure proper ventilation around the unit to prevent overheating.
9. Troubleshooting
If you encounter issues with your mixer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power adapter not connected or faulty outlet. | Check power connections; try a different outlet. |
| No sound output | Output levels too low; incorrect cable connections; faulty speakers/headphones. | Increase 'MAIN MIX' and 'PHONES' levels. Verify all audio cables are correctly connected. Test with different speakers/headphones. |
| No input signal | Input 'GAIN' or 'LEVEL' too low; incorrect input selection; faulty microphone/instrument. | Increase 'GAIN' and 'LEVEL' for the specific channel. Ensure correct input type (XLR for mic, 1/4" for line). Test with another mic/instrument. |
| Distorted audio | Input signal too high (clipping); faulty cables. | Reduce 'GAIN' or 'LEVEL' until level meters no longer consistently hit red. Replace cables if suspected faulty. |
| USB recording issues | Incorrect audio device selection in computer settings/DAW; driver issues. | Ensure 'XENYX Q502USB' is selected as the input/output device in your computer's sound settings and DAW. Reinstall USB drivers if necessary. |
