Nakamichi EC-100 And PS-100

The EC-100 Electronic Crossover provides a simple, and low cost method for multi amplification of loudspeakers. One EC-100 can be inserted between a preamplifier and two stereo power amplifiers to provide bi amplification. Tri amplification and even more sophisticated systems are possible with the multiple use of EC-100's. The EC-100 features simplified crossover frequency selection and individual level controls for the divided channels. Crossover takes place with 12 dB/octave slopes, and compensation circuitry ensures high phase linearity at the selected crossover frequency. A muting circuit is incorporated to eliminate turn on thumps.
