Using The Electronic Crossover
Your search for better sound has led you down the path
towards electronic enlightenment. You are bi-amplifying
your stereo system. By allowing the amplifiers to concentrate
on narrower portion of the audio spectrum, you gain the
benefits of lower distortion, better intermodulation perfor-
mance and more efficient system power handling. The
programmable electronic crossover in the Richter Scale Series
Three is a very flexible means of getting to your goal of
audio nirvana.
The ultra-accurate 24db per octave Linkwitz-Riley cross-
over is generally regarded as one of the best crossover designs
available. It was first publicized by Siegfried Linkwitz and
Russell Riley, two Hewlett-Packard engineers, in a 1976
Journal of the Audio Engineering Society article. This
crossover alignment offers flat amplitude response with a
steep roll-off rate and zero phase difference (lobing error). The
result is a clearer, more accurate sound system.
