ALTO PROFESSIONAL▲lto Professional was founded in 2000 by a passionate team of audio engineers striving to produce products that delivered superior performance at affordable price points for use in live performance settings . Through the use of modern manufacturing techniques, cutting edge DSP technology, and sophisticated design, Alto has succeeded in producing a range of products that provide both exceptional performance and exceptional value for the performing musician and live sound engineer.
 
That’s why we think of ourselves not as a Sound Reinforcement company, but as a Live Performance Reinforcement company. We not only produce tools for the live sound engineer – speakers, amplifiers and mixers – but also tools for the performing musician, including all-in-one PA systems for solo, duo and small group performance settings.
 
Our mission is simple: create products for use in live performance that literally blow away the competition, in terms of accuracy, power, durability, portability, and price.  Every product we design, every component we select and every manufacturing process we use is in service of that simple mission.
 
At ▲lto, we’re dedicated to delivering products that will serve our customers for years to come, stand up to the rigors of the road and provide exceptional performance night in and night out. We’re as passionate about making the tools to help you be heard as you are about the music you create.
