LC7527E - Graphic Equalizer System

Key Features

  • This LSI, in conjunction with a control microprocessor, can implement in two chips, an electronic graphic equalizer with the following features.
  • One touch gain control for each band.
  • One touch memory setting recall allows users to select desired frequency characteristics for each track.
  • Since the LC7527E includes band filter amplifiers on chip, capacitors are the only external components required in.
