Mi-Si "Air Trio" Battery-free MEMS Mic & Element System for Acoustic Guitar

The Mi-Si Air Trio is an active, battery-free MEMS microphone & Element under-saddle pickup system for acoustic guitar. Simply powering up for 60 seconds using the Mi-Si Power Charger will provide you with up to 8 hours of performance time. The Mi-Si Air Trio comes equipped with independent volume controls for the onboard microphone and under-saddle pickup.

Simply mount the module behind the soundhole of your guitar with the included adhesive backed velcro pads, either above the low E or below the high E, wherever you prefer. This will allow you not only to control your overall output level, but also the balance between the microphone and pickup signals.

Who We Are
Mi-Si Electronics Design, Inc. (pronounced "My-Sigh") was founded in April 2004 by an experienced team of engineers with a passion and a drive to make music technology better - for both artists and music lovers. Although new to the marketplace, Mi-Si's engineers bring an arsenal of expertise and more than 25 years experience in the amplification field, developing exciting and revolutionary electronics specifically designed for acoustic amplification.

Our Philosophy
In the past, conventional circuit design components have been a burden to acoustic musicians, incurring extra cost, requiring additional space, and decreasing reliability and tonal quality. Making a signal pass as simple as possible has not been a luxury, but a necessity. This knowledge is the driving force behind Mi-Si’s approach – minimalist design with maximum functionality. Musicians have known this all along, the fewer obstacles between your pickup and your amp, the better your sound.

Battery-Free
After more than 25 years of designing and building preamps, Mi-Si’s team of engineers proudly introduces a truly significant and unique breakthrough: a high-performance, fully active preamp that does NOT NEED BATTERIES. No 9-Volt, no AA, no AAA, no lithium - NO BATTERIES at all. A special blend of new energy sources with very low-power components and our ability to design compact and efficient circuits make our battery-free products a reality. 0 to 60 To enjoy the benefits of Mi-Si’s Battery-Free Technology, all you have to do is power-up for 60 seconds, providing you with 8 hours of performance time (or 16 hours in the case of the Simple Jack). Our extremely energy-efficient design not only means no batteries, but no battery wires, no dead or fading batteries, no RF interference, no battery compartments, and no need to remove a battery from your instrument before transportation.

Good News for the Whole Planet
Every used battery is a hazardous waste and needs to be properly disposed of to avoid toxic chemicals leaking into soil and waterways. Our environmentally conscious and advanced designs eliminate this waste. Our products are created with one goal in mind – to provide the highest quality performance while being as frugal as possible regarding energy consumption. We are proud to play a role in furthering the aspirations of musicians, in addition to helping our planet.
