Behringer 1004 Oscillator Module

Features

• Classic 1004 dual analog VCO module from the 70s
• Authentic reproduction of the circuitry from the 2500 Series
• VCO features 5 waveforms: sine, triangle, square, sawtooth and pulse
• Waveforms can be combined and inversed into the audio outputs
• Output frequency range from 0.03 Hz to 16 kHz in 2 ranges
• VCO range selectable between Low (LFO) or High (Audio)
• Coarse frequency control allows adjustment over 10 octaves
• Fine frequency control adjusts over +/- 1 octave
• Frequency modulation with 2 inputs and controls responding to 1 V/octave
• The width of the pulse waveform can be set manually and controlled dynamically
• Eurorack specs: 16 HP, XX mA +12 V, XX mA -12 V
