19" 1U power amplifier designed to drive a ButtKicker LFE with a maximum output of 500W at 4 Ohms.

The Shaker Amp 400 features a microphone preamp with switchable 48V phantom power and a -16 dB pad switch, allowing for direct connection of bass drum microphones.

The XLR-jack combo socket includes a parallel output for looping the input signal.

The built-in switchable active crossover (adjustable low-pass from 40 to 200 Hz / 12 dB/oct) and a switchable high-pass at 20 Hz optimize the signal for the shaker's working frequency as needed.

Perfectly paired with the Fischer Amps "In Ear Amp" or a mixing console!

Shaker Amp 400 and ButtKicker LFE come with a universal mount for attachment to a drum stool.
