  • Anotaciones

  • A hi-fi Stereo Electronic Crossover unit housed in a metal case with wood trim, for use with the Pioneer SC-700 Stereo Preamplifier and Pioneer SM-700 Power Amplifiers. Used with a stereo preamplifier, it is the link to the main amplifier stage in a 2-Channel or 3-Channel multi-amp system, providing complete control, matching source, speaker systems and individual room acoustics. The most suitable crossover frequencies, and the cutoff characteristics at the crossover points are easily chosen and controlled.
