3 Independent Channels, Infinite Possibilities
MIC CHANNEL
A microphone channel is essential for any busking amplifier, and the SA-100 delivers. With 60dB of gain, it ensures rich, clear vocals whether you’re using a dynamic or high-impedance dynamic mic. For condenser mics, the SA-100 offers 48V phantom power, which can be easily activated when needed. Built-in delay and reverb effects further enhance your vocals with added depth and texture. Plus, the versatile combo jack input accommodates both XLR and 1/4" plugs for maximum flexibility.
GUITAR CHANNEL
In addition to its Class A discrete analog preamp, which guarantees warm, clear, and rich guitar sounds, the PASSIVE button is your secret weapon. When your acoustic guitar is equipped with a passive pickup system or a high-definition, low-volume active pickup system, enabling the PASSIVE button boosts the guitar channel's input gain to ensure your guitar sounds its best.
INSTRUMENT CHANNEL
While the MIC and Guitar channels are ideal for solo or duo performances, the INST. Channel takes versatility to the next level. It allows you to connect digital wind instruments, digital pianos, electronic drums, or other line-level instruments. You can also plug in a second microphone, using the MIC/LINE button to select the appropriate input.

5 Presets: Consistency, Convenience, and Creativity
The NUX SA-100 features 5 user preset slots, giving you the flexibility to save and recall your custom settings for all 3 channels with ease. Whether you’re fine-tuning tones for different sections of your performance or switching between styles, you can effortlessly switch presets using the Stageman app or the included dual-foot switch. Perfect for adapting to any musical moment, it ensures you're always ready with the ideal sound.
