A triode pentode is used in a wien bridge to operate as a sinewave oscillator. The oscillator´s frequency is controlled through a vactrol, manually or with a voltage from 20Hz to 5kHz. The resonance/waveshape parameter controls the cleanliness of the sine w ave, below a value of 10% THD.
The tubes protrude ca. 38mm! This will fit the lid of a Doepfer flightcase, though.
The R-54 module is protected against reversed polarity, overvoltage, undervoltage and incorrect hookup to external equipment.
audio input, audio output, 3x pitch CV inputs
3U Eurorack module, 22HP wide, ca. 25mm deep
Current draw 150mA. And 2x to 2.5x more when heating up!
