The generator creates a reference tone at 440 Hz for tuning guitar, piano, and other instruments. You can set any frequency for alternative tunings.
| Test | Frequencies | Purpose |
|---|---|---|
| Bass | 20–200 Hz | Subwoofer check |
| Midrange | 200–5000 Hz | Speaker quality |
| Treble | 5000–20000 Hz | Tweeter clarity |
By smoothly changing the frequency from 20 to 20000 Hz, you can determine your individual hearing range. The upper limit decreases with age.
