System Block Diagram
The device was remarkably simple. The power source was sent through a transformer and a series of capacitors in order to filter it down to the power supply needed for the individual chips on the board. When the device was powered and an audio signal was sent into Line In, the signal was sent through an equalizer IC which divided the signal into various wavelengths. Each one of these wavelengths was sent through a voltage divider, where the user was able to change one of the resistances via the sliding knobs on the front of the device, therefore changing the gain for that wavelength. Finally, all of the signals were MUXed and sent to Line Out.
