Bose Professional S1 Pro Plus System with Battery Akutoitega PA süsteem

Portable PA Power for Performers Who Move

The Bose S1 Pro+ Wireless PA System with Battery is a self-contained, battery-powered PA built for musicians, presenters, and mobile entertainers who refuse to be tied to a wall outlet. At 6.5 kg with an integrated carry handle, the system travels from car to curb to stage in one trip and runs for up to 11 hours per charge. The S1 Pro+ is the right choice for performers who need professional-grade sound, wireless freedom, and stage-ready flexibility in a single box.

What Sets This System Apart in the Portable PA Category

Four positioning modes — elevated surface, tilted-back floor, monitor wedge, and 35 mm stand-mount — work with internal Auto EQ sensors that automatically re-tune the system the moment it is reoriented. Integrated OLED displays physically rotate to match the chosen position, so every control stays readable from any angle. The unit also ships with a factory-installed Li-ion battery and built-in wireless receivers, so optional RF transmitters for mic and instrument dock inside the enclosure, charge while stored, and pair in seconds.

Even, Room-Filling Coverage From a Single Box

Bose engineered the enclosure to project sound from the front and sides simultaneously, eliminating the hotspots that plague smaller portable PAs. A 120° horizontal by 50° vertical dispersion pattern keeps listeners at the edges of a room hearing the same mix as those in front.

• Coverage (H × V): 120° × 50° — wide, even throw for cafés, bars, and small venues
• Max SPL @ 1 m: 109 dB — enough headroom for solo acts, duos, and speech reinforcement
• Transducers: 1 × 152 mm woofer + 3 × 57 mm tweeters — full-range response without an external sub

A 3-Channel Mixer Built Around ToneMatch

Channels 1 and 2 carry independent EQ, reverb, and ToneMatch processing with one-touch presets for vocals and acoustic guitar. Channel 3 handles stereo Bluetooth streaming, a 1/4" TRS aux input, and a 3.5 mm source. A USB-C port enables Live Stream mode, which routes a dual-mono mix straight into a computer's DAW for recording or online performance.

• Channels: 3 (2 mic/instrument + 1 Bluetooth/aux) — covers a full solo or duo setup
• Insert / FX Loop: 1/4" TRS insert on Ch 1–2 — patch in guitar pedals or outboard effects
• Live Stream Mode: USB-C audio interface — record or broadcast without an extra interface

Built for Load-In, Load-Out, and Anywhere In Between

The polypropylene enclosure and powder-coated steel grille shrug off daily transport, and the universal 100–240 V power supply means the same unit works across European, UK, and US mains. The factory-installed Li-ion battery delivers up to 11 hours of playback, and the optional S1 Pro+ System Battery Pack extends runtime further.

• Dimensions (H × W × D): 333 × 239 × 279 mm — fits in a car seat or backpack
• Net Weight: 6.5 kg — single-handed carry from vehicle to stage
• Battery Runtime: up to 11 hours — covers full gigs, ceremonies, and after-parties

Solo Performers, Mobile DJs, and Event Hosts

This portable PA is the right choice for singer-songwriters, acoustic duos, mobile DJs, fitness instructors, and house-of-worship speakers who need a self-contained rig that sets up in under a minute. Schools and universities can deploy it for assemblies and outdoor ceremonies, while hospitality venues use a pair for stereo coverage at cocktail hours and receptions. Anyone who has wrestled with cables, mixers, and stands will appreciate the cable-free wireless RF transmitters, the on-board ToneMatch presets, and the Bose Music app that puts full remote control in a phone.

The Bose Professional Portable PA Lineage

Bose Professional designed this system as the next step in its portable PA family, building on the original S1 Pro with wireless RF integration, USB-C Live Stream mode, and OLED controls. The unit is part of a broader ecosystem that includes the L1 Pro8, L1 Pro16, and L1 Pro32 line arrays, all of which can share a stage or stream audio together via Dual Wireless Streaming in the Bose Music app.
