ButtKicker BK-GR2 Mini Power Amplifier and Gamer2 Transducer Kit

A compact, fanless, digital mono amplifier designed to power ButtKicker low-frequency transducers, such as the BK-GR2 Gamer2, Advance, mini-LFE, mini-Concert, and BK4-2. Commonly used in gaming chairs, home theater seating, and sim racing or flight simulator setups, this amplifier enables a highly immersive tactile experience by driving transducers that convert low-frequency audio into physical vibrations. These vibrations simulate the impact of effects like gunfire, explosions, engine rumble, and musical bass directly through the user’s chair, enhancing realism without increasing overall volume. The unit includes high and low frequency roll-off controls and a wired remote for convenient operation, even when hidden from view. The rear panel supports daisy-chaining up to four units via RCA input and output jacks for larger installations. A signal indicator LED shows active input, while a clip LED warns when output approaches its limit.
