Nux AC-25 Combo elektroakustiselle kitaralle

Portable Battery-Powered Acoustic Amplifier for Street and Stage

Busking, park jams, and unplugged sessions demand an amplifier that travels light and performs loud. The NUX AC-25 answers that call with 25 watts of power, a built-in rechargeable battery, and dual-channel connectivity — all packed into a compact enclosure measuring just 280 × 218 × 220 mm. Weighing only 5 kg, this acoustic guitar amplifier is engineered for musicians who refuse to stay tethered to a wall socket. Whether setting up on a cobblestone street corner or playing a backyard gathering, the AC-25 delivers warm, natural acoustic tone without the need for external power.

Amp Modeling and App-Controlled Tone Shaping

What sets this model apart from conventional acoustic amps is its onboard modeling engine, offering two distinct voicings: the Stageman model (based on NUX's flagship acoustic amp, with rich bass response and warmth) and the LBox model (inspired by a renowned US acoustic amp brand, delivering transparent, hi-fi acoustic tone). Beyond the front panel, the free Stageman app for iOS and Android unlocks deeper editing, a built-in drum machine, and Bluetooth audio streaming for backing tracks.

Speaker Output and Tonal Character

Faithful acoustic amplification hinges on the quality of the speaker. A full-range driver paired with a 25 W RMS power stage projects clear, undistorted sound at volumes suitable for small venues and outdoor performance.

• Speaker Size: 16.5 cm — full-range driver optimized for acoustic instrument frequency response
• With 25 W RMS output power, you get enough headroom for intimate gigs, busking spots, and rehearsal rooms without unwanted distortion.
• Amp Models: Stageman, LBox — two voicings let you switch between warm, bass-rich tone and transparent, studio-like clarity

Dual-Channel Input and Wireless Connectivity

Singer-songwriters and duo performers benefit from the two-channel layout: Channel 1 accepts a 1/4-inch instrument cable with 1 MΩ input impedance, while Channel 2 features an XLR microphone input at 2 kΩ impedance. A dedicated headphone output enables silent practice, and a line output routes signal to a PA system or recorder.

• Channel 1 Input: 1/4-inch jack, 1 MΩ impedance — optimized for piezo and magnetic acoustic pickups
• Dynamic microphones for vocals or secondary instruments are supported on Channel 2, thanks to the XLR connector and 2 kΩ impedance.
• Bluetooth — dual-mode wireless handles both audio streaming for backing tracks and real-time app control from your phone

Battery Runtime and Travel-Friendly Design

Freedom from power outlets is the defining advantage of this amplifier. The internal lithium battery pack provides up to 4 hours of continuous playing time — enough for a full busking set, a park performance, or an extended rehearsal. When mains power is available, the included 12 V / 2.5 A adapter keeps the battery charged.

• Battery Life: Up to 4 hours — covers a typical street performance or outdoor session without recharging
• Battery Capacity: 12.6 V / 3000 mAh — lithium cells maintain consistent output voltage throughout the discharge cycle
• Measuring 280 × 218 × 220 mm, the amp fits easily into a backpack or guitar case accessory pocket.

Acoustic Performers Who Need Mobility

Street performers, singer-songwriters, and mobile entertainers will find the AC-25 purpose-built for their workflow. The dual-channel design means a solo artist can plug in both guitar and microphone without carrying a separate PA. Acoustic duo acts gain a compact, battery-powered monitoring solution that eliminates the need for venue power. The NUX AC-25 is the right choice for acoustic musicians who need a lightweight, self-contained amplification system that sounds natural and works anywhere — from coffee shops and park benches to backyard parties and busking corners.

NUX Stageman Series Heritage

The AC-25 belongs to the Stageman family of acoustic amplifiers, a product line designed from the ground up for portable performance. Its Stageman model name inside the amp's modeling engine references NUX's earlier full-size acoustic amplifier, carrying forward that signature warm bass response into this compact format. Combined with the LBox voicing — inspired by one of the most respected names in acoustic amplification — the AC-25 brings studio-grade tone options to a battery-powered, street-ready package.
