Brings Motion and Magic to Live Keyboards

Ever wish you could enjoy the same sound quality onstage that you do in the studio? With the Motion Sound KP-612S, you can. This 650-watt, 2-channel 2 x 12” keyboard amplifier brings the same deep, dynamic, lush soundscape to your live performances that you hear through your studio monitors and headphones. The KP-612S works equally well for hardware- and software-based instruments and includes Motion Sound’s proprietary 3D Expander, delivering top-shelf sound and ultra-realistic three-dimensional imaging. The Motion Sound KP-612S is guaranteed to add motion and magic to your live keyboards.

650 watts of power in a portable combo amp

The KP-612S features two stereo channels, rated at 250 watts each if both are employing 8-ohm loads. That said, if you’re using the subwoofer option, its signal comes from the power amplifier’s left channel, which when split between the external subwoofer and the KP-612’s built-in woofer, results in a 4-ohm load on the amplifier, rated at 400 watts. The power output to the right channel remains an 8-ohm load, rated at 250 watts. Combining the left channel’s 400 watts with the right channel’s 250 watts is where the 650-watt total comes from.

Ultra-realistic 3D imaging

At Sweetwater, we’re impressed by the KP-612’s incredible imaging. Not only does this combo amplifier’s V-shaped angled cabinet dramatically widen your stereo sound field, you can also enhance your stereo field further via Motion Sound’s proprietary 3D Expander. The end result sounds incredibly three-dimensional, with tons of dramatic motion.
