Hi-Z to Balanced-Output Converter PUBLIC

High-Impedance to Balanced-Output Converter-
Circuit Including 1-into-3 High-Impedance Splitter

High-impedance to balanced-output circuit for electric guitar, featuring in-phase high-impedance output, out-of-phase high-impedance output, buffered high-impedance output, and balanced (low-impedance) output. Controls Include: Gain, Drive, Tone, High-Z Level (for the in-phase and out-of-phase outputs), and a Balanced Level control. Suitable for stomp-box or rack-mount applications. Batteries can be replaced by a regulated dual-polarity +-9V DC power-supply providing at least 50 mA of available current. High-fidelity circuit. Can be used for studio recordings. Range for frequencies > 0 dBV is from 29 Hz to 6.3 kHz. Low -3 dB reference is 28 Hz. High -3 dBV reference is 10 kHz for high-Z outputs and 9 kHz for balanced output. 20 kHz limit is down by -10 dB for high-Z outputs, and -13 dB for the balanced output. High-impedance in-phase and out-of-phase gains with all controls at 50% are both 10.5 dBV @ 1 kHz, while the buffered high-impedance gain is 12.2 dBV @ 1 kHz with all controls at 50%. The balanced output gain is 10.2 dBV @ 1 kHz with all controls at 50%. All gains double when all controls are at 100%.
