The 7B SST is a MONO block design capable of over 600 watts at 8 ohms and over 900 watts at 4 ohms. This gives the 7B ST the power to drive, with breath-taking ease and clarity, speakers, which have been considered "impossible" loads in the past. One advantage of the Mono design 7B SST is it allows you to place the amplifier adjacent to the loudspeaker providing improved performance. The 7B SST is available in either a Series or Parallel version. ''Series'' is recommended with loudspeaker loads above 3 ohms and ''Parallel'' for loudspeaker loads below 3 ohms.
