After more than 25 years of designing and building preamps, Mi-SiÕs 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 Š NO BATTERIES at all!
Every used battery is a hazardous waste and needs to be properly disposed of to avoid entrance of toxic chemicals into our soils and waterways. Our battery-free technology is environmentally conscious and designed to eliminate this disposal problem.
Our technology is much more than just a battery-free concept. Our preamps have the most natural and the least quacky sound on the market. Mi-SiÕs custom linearization scheme allows us to get the best possible sound from a piezo pickup.
Obviously, the less stuff put in the instrument, the better its mechanical and acoustical integrity is preserved. This philosophy is the driving force behind Mi-Si's approach - the minimalistic design with the maximum functionality.
