Mi-Si Electronics Design | State of the Art Battery-Free Acoustic Amplification

Motif

The Mi-Si Motif Acoustic Guitar System continues Mi-Si’s pattern of innovation in acoustic amplification. It includes a high-performance, endpin-mounted preamp featuring Mi-Si’s now classic battery-free technology, while introducing the world’s first Active Under-Saddle Condenser Pickup.

This breakthrough pickup offers all the benefits of conventional under-saddle applications. It’s highly responsive with low feedback, allows the player freedom of movement, and does not impair your instrument’s appearance. It is only 1 mm thick, providing superior contact with your guitar’s bridge and saddle, with much less impact on its structural integrity.

Eliminating the harsh characteristics of more typical piezo-electric technology, Motif captures the full richness and depth of your acoustic guitar. The system is completed by a low-noise Class A discrete preamp mounted directly to the endpin output jack. And like any other Mi-Si product… it’s battery-free.

Charge Motif for 60 seconds via the output jack and you’ll have 6 hours of exceptional acoustic amplification.

Magpie

Mi-Si Magpie Magnetic Soundhole Pickup includes the revolutionary new active, battery-free magnetic soundhole pickup for acoustic guitar and the Mi-Si Power Charger.  Magpie pickup employs a unique “planar” single coil design – less susceptible to AC hum than traditional bobbin wound pickups.  This design provides much broader sound and reduces the overall weight – combining the benefits of a single coil pickup with the virtually hum-free operation of a humbucker.

Powering up Magpie for 60 seconds with the Mi-Si Power Charger will provide you with up to 8 hours of performance time.

Acoustic Duo (retired)

The Mi-Si Acoustic Duo system includes the revolutionary new Flux 2.0 active battery-free magnetic soundhole pickup for acoustic guitar with the Mi-Si power charger. The Flux 2.0 pickup employs a unique “planar” single coil design – less susceptible to AC hum than traditional bobbin wound pickups. This design combines the benefits of a single coil pickup with the virtually hum-free operation of a humbucker. It is an ACTIVE magnetic pickup, so you don’t have to worry about the cable capacitance or input impedance of your system – the pure and natural sound of your acoustic guitar will not be altered.

Power up the Acoustic Duo for 60 seconds with the Mi-Si Power Charger for up to 8 hours of performance time.
