The Quilter 200 Series Blocks take performance to a whole new level. Our internal 400 watt class-D powerplant provides unparalleled power reserves, but no worries -- our fully effective Master control regulates peak power from zero to 200 watts, with no loss of tone or overdrive, so you can set the wattage to match your speaker ratings. The additional 200 watts provides voltage overshoot, tonal boost, and impedance flexibility, overcoming the typical limitations of "solid state watts". This is just one aspect of our incredible patented technology that combines boutique tone quality with unbelievable power that sits in the palm of your hand. Use with any good speaker, or pair your Block with one of our BlockDock™ series cabinets for the flexibility of a head with the portability of a combo!
