Yamaha STAGEPAS 100BTR MKII Portable PA Speaker with Battery
Yamaha STAGEPAS 100BTR mkII Battery Powered Portable PA System with Bluetooth & USB Audio I/O
The Yamaha STAGEPAS 100BTR mkII is a compact, battery powered portable PA system designed for musicians, performers, presenters, educators, buskers, content creators and anyone who needs clear, reliable sound without being tied to mains power. Combining a 100W Class-D amplifier, built-in mixer, Bluetooth audio playback, USB audio I/O and an internal lithium-ion battery, it gives you a highly portable all-in-one sound solution for performance, speech, playback and streaming.
Despite its small footprint, the STAGEPAS 100BTR mkII is built to deliver proper Yamaha PA performance. Its coaxial speaker design combines a 1.4" high-frequency driver and 6.5" low-frequency driver, supported by Yamaha FIR-X filtering for clear projection, natural dispersion and well-balanced sound across vocals, instruments and backing tracks.
With up to 6 hours of battery-powered operation, the STAGEPAS 100BTR mkII is ideal for outdoor performances, mobile events, rehearsals, lessons, small venues, presentations and hybrid setups where plug-in power is not always available. It is simple to set up, easy to carry and flexible enough to handle everything from solo acoustic sets to spoken-word use and portable music playback.
Why Choose The Yamaha STAGEPAS 100BTR mkII?
Battery Powered Freedom
The built-in lithium-ion battery gives you the freedom to perform, present or play music in places where mains power is not practical. With up to 6 hours of continuous operation, it is a great choice for busking, outdoor events, schools, community spaces, markets, garden parties and pop-up performances.
Compact Yamaha PA Sound
The STAGEPAS 100BTR mkII uses a 100W Class-D amplifier and a high-quality coaxial driver design to produce clear, focused sound from a compact enclosure. It is small enough to carry easily but powerful enough for intimate live performances, rehearsals, speech and background music.
Built-In 3-Channel Mixer
With two mono mic/line inputs and one line input, the built-in mixer lets you connect microphones, instruments and playback devices without needing a separate mixing desk. Channel 2 also supports Hi-Z input, making it suitable for direct connection of compatible high-impedance instruments such as electro-acoustic guitars.
Bluetooth Audio Playback
Bluetooth connectivity makes it easy to stream backing tracks, interval music, rehearsal audio or presentation sound directly from a phone, tablet or other compatible device. The mkII model also supports Bluetooth audio I/O functionality, making it more versatile for modern mobile and hybrid applications.
USB Audio I/O For Hybrid Use
The STAGEPAS 100BTR mkII adds USB audio I/O, allowing audio to be sent to and from a computer or smartphone. This makes it especially useful for livestreaming, online lessons, remote seminars, content creation and hybrid performance setups where you need a compact PA that also works with digital devices.
Smart Portable Design
The integrated carrying handle doubles as an adjustable stand, helping you angle the speaker towards your audience when placed on the floor. It can also be mounted using a 3/8" screw hole, giving you more control over sound projection in different spaces.
Why Choose A Battery Powered Portable PA?
A battery powered portable PA gives you a complete sound system that can work almost anywhere. Unlike a regular Bluetooth speaker, a portable PA is designed for microphones, instruments, speech and performance, making it far more suitable for musicians, presenters and public-facing events.
For solo performers, it means you can take vocals, guitar and backing tracks to small gigs or busking sessions with minimal setup. For teachers, instructors and presenters, it gives speech clarity and music playback without needing a venue’s built-in sound system. For content creators and hybrid users, USB and Bluetooth audio I/O make the STAGEPAS 100BTR mkII a practical bridge between live sound and online audio.
Who Is It For?
Beginners
A great option for first-time performers, speakers or educators who want a simple, reliable PA without needing a separate mixer, amplifier or speaker setup.
Intermediate Musicians & Performers
Ideal for singer-songwriters, acoustic performers, buskers, small ensembles, DJs needing a compact monitor or anyone needing a portable sound system for rehearsals and small events.
Advanced & Professional Users
Useful as a compact grab-and-go PA, presentation system, livestream audio solution, small rehearsal speaker, keyboard/acoustic monitor or portable speech system for professional environments.
