NUX Battery-Powered 100W Acoustic Guitar Amplifier

Portable, Rechargeable, All-in-One Amplifier for Busking & More

The NUX SA-100 is a rechargeable amplifier built for busking, live streaming, and recording. It features a warm,

Class A discrete analog preamp, high-quality DSP-driven digital effects, and a powerful 100W peak Class D amplifier. With its advanced five-speaker setup—an 8-inch bass driver and four 2.75-inch tweeters—it delivers deep lows, clear highs, and impressive volume, making it the perfect choice for busking and outdoor events.

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 condensermics, 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.

INST. 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.

Built-in Drum Machine & Looper
The NUX SA-100 features 9 drum patterns and a 60-second looper with unlimited overdubs, making it an ideal tool for both practice and live performances. Whether you're building layers or creating intricate rhythms, it gives you the flexibility to enhance your sound on the spot.

Dual-footswitch, included.
The NUX SA-100 includes the NUX NMP-2 Lite dual footswitch, designed for essential tasks like switching presets, enabling/disabling effects, and controlling the looper and drum machine. To enhance your experience, you can customize the functions of both footswitches and save them as a preset. With 5 available presets, you can easily switch between different settings, such as reverb, chorus, and preset changes, all with ease.

Loud on its own, even louder when paired.
The wattage of a speaker determines its power, but loudness depends on more than just watts. Factors like speaker sensitivity and acoustic design play a key role. The NUX SA-100 is a 100-watt full-range speaker that delivers clear, powerful sound on its own. Pair it with another SA-100, and you’ll get even greater volume and a wider sound field, perfect for larger, noisier environments.

Live Streaming/Recording Made Easy
The SA-100 makes live streaming and recording effortless. Simply connect via the USB or PHONE interface to send the speaker's sound to your phone using OTG or TRRS for seamless live streaming.
Additionally, the USB interface allows the SA-100 to function as an audio interface for your computer, enabling easy recording directly into your DAW or recording software.

6 Hours of Playtime
The SA-100 is powered by a 5200mAh rechargeable LiPo battery, delivering up to 6 hours of playtime on a full charge. For added convenience, the back panel includes a 9V DC output jack, allowing you to power external instruments or pedals while performing.

Effortlessly Portable with Trolley Bag
The SA-100 comes with a convenient trolley bag, making transportation a breeze. With its sturdy design and wheels, you can easily move the amp from one gig to the next, ensuring hassle-free portability wherever you go.
