EQ Scenes
The NUX B-6 features three EQ scenes optimized for different types of saxophones. These settings adjust the frequency response to best suit the instrument's characteristics:
- Soprano Saxophone: Optimized for the brighter, higher-pitched sound of a soprano sax.
- Alto Saxophone: Tailored for the balanced and versatile tone of an alto sax.
- Tenor Saxophone: Designed to enhance the rich, warm sound of a tenor sax.
Refer to the transmitter unit for controls to switch between these EQ scenes. Experiment with each setting to find the one that best complements your instrument and playing style.
