Markbass SD 800

 

When you need speed and clarity at high volumes, especially in big-stage applications, the digital power amp SD800, delivers 750W of power into a 4 ohm cab or 450W into an 8 ohm cab. Recommended for use with big cabinets (8X10, 6X10, or 2X15), or two-cabinet rigs, this little solid-state head gives you plenty of headroom and has several options for protecting and shaping your sound, from it's VLE (Vintage Loudspeaker Emulator) and VPF (Variable Pre-shape Filter) options to the Pre/Post EQ setting which allows you to choose whether your line out signal is affected by the amp's EQ.
