Behringer B1X Battery powered PA system

Behringer B1X — 250W Battery-Powered PA with Built-In Mixer

The Behringer B1X is a portable all-in-one PA speaker that delivers 250 watts of Class-D power to small and midsize venues without mains electricity. A 6.5" long-excursion woofer and three angled 2.5" full-range drivers cover a 60 Hz to 20 kHz frequency range, while the integrated 4-channel digital mixer and Klark Teknik TC FX engine handle shaping and effects. The onboard lithium-ion battery delivers up to six hours of cable-free operation.

Klark Teknik FX and Wireless-Ready Architecture

What separates this model from typical battery speakers is Klark Teknik TC FX processing — British-engineered reverb and dynamics trusted on professional touring rigs. A dedicated USB-A port accepts Behringer ULM Series wireless microphone dongles, eliminating cable runs between speaker and performer. The free iOS/Android app exposes volume, gain, EQ, FX, delay, and preset control from across the room.

Amplification and Battery Runtime — Cable-Free Performance

A Class-D amplifier stage delivers 250 watts with a maximum SPL of 108 dB, enough to cover audiences in cafés, conference rooms, and small clubs. The internal lithium-ion battery provides up to six hours of playback per charge, with AC fallback for permanent installations.

• Amplifier Power: 250 W Class-D — headroom for vocals and acoustic instruments
• Maximum SPL of 108 dB keeps speech intelligible and music full-bodied at the back of the room
• Battery Runtime: up to 6 hours on a single charge for cable-free gigs

Driver Layout — Full-Range Coverage from a Single Cabinet

The two-way cabinet pairs a long-throw 6.5" woofer for low-end punch with three angled 2.5" full-range drivers that spread high frequencies across the listening area.

• Woofer: 1 x 6.5" long-excursion driver — handles bass down to 60 Hz
• Three angled 2.5" full-range drivers spread high frequencies across the listening area for seated and standing audiences
• Frequency Range: 60 Hz – 20 kHz (±3 dB) — full-range response without a subwoofer

Inputs, Outputs, and Wireless Integration — Mixer Built In

Two combo XLR / 6.3 mm jack inputs cover dynamic mics and instruments, a 3.5 mm AUX input handles phones or laptops, and an XLR line output feeds a second speaker or recording device.

• Mic/Line Inputs: 2 x XLR / 6.3 mm combo — accepts balanced mics and unbalanced instruments
• AUX Input: 1 x 3.5 mm mini-jack — quick connection for phones and media players
• Bluetooth TWS pairs two cabinets for true stereo playback, while the USB-A port accepts ULM Series wireless microphone dongles

Built for Solo Performers, Presenters, and Mobile Event Pros

The B1X is the right choice for solo musicians, acoustic duos, and mobile DJs who need a self-contained PA that runs on battery power and fits in a car. Presenters and MCs benefit from wireless ULM microphone support and remote app control for adjusting levels from across the stage. Wedding operators get a quick-setup system that pairs two cabinets via Bluetooth TWS for true stereo coverage.
