If you have an external audio device connected to the audio inputs on the SPD-SX, and you're not able to monitor the sound or view signal levels while in the Sampling menu, then it's possible that the Audio Input / Out parameter is set incorrectly. Use the following steps to choose "MASTER" for the Audio Input/Out setting:
- Press MENU.
- Cursor to highlight the "SYS" icon, and then press ENTER.
- Cursor to highlight "AUDIO IN/OUT," and then press ENTER.
- Highlight "AUDIO IN," and then press the + or - button to choose "MASTER."
- When you're finished, press the KIT button to exit. The new setting is saved automatically.
