Yamaha STAGEPAS 100BTR mkII Portable PA System

Portable power meets professional clarity in the Yamaha STAGEPAS 100BTR MKII, a 100W battery-powered PA built for performers, educators and mobile creators who need great sound anywhere. This light 12 lb. system combines a high-quality coaxial compression driver with Yamaha’s FIR-X crossover technology to deliver clean, consistent coverage and impressive output for its size. Bluetooth and USB connectivity expand streaming and hybrid workflows, while the built-in three-channel mixer and internal lithium-ion battery make it effortless to set up, perform and pack out. Whether indoors or outdoors, the STAGEPAS 100BTR MKII gives you polished sound with virtually no setup time.

High-Performance Coaxial Driver Technology for Exceptional Clarity

Sound quality takes a noticeable leap forward thanks to a refined 6.5" LF/1.4" HF coaxial compression driver designed to deliver articulate, natural performance across the entire 90° × 90° coverage pattern. Yamaha’s FIR-X crossover ensures the high and low drivers work in precise phase alignment, producing smooth transitions and clarity normally found in fully featured pro systems. Capable of reaching up to 120dB SPL at 3.28', the STAGEPAS 100BTR MKII delivers enough output for small-to-mid-sized crowds with vocal presence, acoustic detail and playback definition that feel far bigger than its compact frame suggests.

Portable Design and Fast, One-Handed Setup

Mobility is a defining strength of this system. At just over 12 lb., the cabinet is light enough for true one-handed transport, yet sturdy enough for travel, busking and daily use in classrooms or corporate environments. Setup is equally streamlined: rotate the built-in bottom handle to position the speaker, power on and start performing—no stands or extra hardware required. For creators who travel frequently or perform in tight spaces, the optional BAG-STP100 carrying bag keeps the system organized and protected between gigs.

Built-In 3-Channel Mixer With Hi-Z Support and EQ

A three-channel mixer makes the STAGEPAS 100BTR MKII a complete, ready-to-use system even without additional equipment. Two combo inputs handle microphones or line sources, with Channel 2 offering Hi-Z capability for plugging electric guitars and basses straight in. A stereo mini input provides an easy path for backing tracks or media playback, while a 2-band master EQ shapes your overall tone for the room. When more coverage is needed, an XLR mix out lets you route the signal to additional speakers or front-of-house systems.

Hybrid Audio I/O, Bluetooth and Long-Lasting Battery Power

Modern workflows benefit from flexible audio connectivity, and this PA is built with that in mind. USB-C 2-in/2-out streaming makes it ideal for livestreams, remote teaching and hybrid presentations, while Bluetooth 5.0 enables stable wireless playback for backing tracks or music between sets. The internal 60Wh lithium-ion battery offers up to six hours of operation—perfect for ceremonies, outdoor performances and pop-up events without power access. When it’s time to recharge, USB Power Delivery support brings the battery back to full in roughly two and a half hours.

Combining pro-level sound, extreme portability and modern connectivity, the STAGEPAS 100BTR MKII is a versatile solution for musicians, instructors, presenters and creators who need reliable performance anywhere. With Yamaha engineering ensuring clear, consistent results in any environment, this compact PA keeps your message—your music—powerful and present, wherever the day takes you.
