Analogue Systems - RS-35N

The RS-35N External Processor contains three circuits for extracting control voltages from an audio signal: frequency-to-voltage generator, level-to-voltage generator and a trigger generator. It has a new faceplate. Frequency-to-voltage (FREQ-V): This circuit of the RS-35 circuitry is also known as "pitch-to-voltage converter". It analyzes an audio signal and creates a frequency dependent control voltage. The higher the frequency the higher the voltage is. the input accepts signals of ±10V. The V-Slew control can smmothen abrupt changes in the output signal and thus create a portamento up to 2S length.The "V-range" switch determines thevoltage range at the output. In the 1V/oct mode it will generate a control voltage with !V/osctave characteristic and a range of -4V to 3V. In VARY mode the "vary depth" control sets the onversion range from 0V to 0.5V/oct. In this mode the voltage range at the output is -10V to 6V.The switch "F-Range"sets frequency range to be analyzed. "kHz" converts
