Hex-Preamp: Tone Circuit PUBLIC

Hex-Tone Circuit for Hex-Preamp or Hex-Amp System

Hex-Tone circuit for Hex-Preamp proposal or Hex-Amp System proposal. Accepts the individual string signal outputs from a Hex-Preamp. One circuit shown. Six required, identical except for capacitors C1 = C2, and C3, in the Input Stage, which are customized for each string. The capacitor values and corresponding frequencies are given in the diagram. Controls Include: Gain, Bass, Center (of Midrange band), Treble, High Trim, and Volume. Provides up to +35 dBV boost with all controls at 100%. The power-supply is not shown. Requires a regulated dual-polarity DC supply providing +-15 VDC @ >= 30 mA per circuit (180 mA for all six circuits). Experimental Circuitry! Fully breadboard test before committing to a soldered build. See complete Hex-Amp system under "Amplifiers" heading at https://kurtusrichtersblog.com .
