The Dual VCO is a 4hp dual voltage controlled analog oscillator. Each VCO has square, triangle, and sine wave out, coarse and fine tuning controls, a control voltage input, and a switch for selecting exponential or linear cv in. When a control voltage is inserted, the fine tune control becomes an attenuator for the incoming voltage. In exponential mode, when the attenuator is fully clockwise, the VCO will track around 5 volts per octave. Each VCO runs from 0.2 hz (5 seconds a cycle) up to 18k hz
Very Stable, Temperature compensated- waveform outputs 10vpp current consumption: +12v 20mA, -12v 38mA 45mm deep
There are a couple quirks to these 8038 VCOs: Below 300 hz the waveform symmetry is slightly off. triangle waves get a little uneven in the lfo range, the sine is not completely perfect to begin with the bottom trough and in the lfo range it slopes slightly, and the square turns more trapezoidal above
