Used Doepfer A-147-5VE Quad LFO

Module A-147-5VE contains four voltage controlled low frequency oscillators (VCLFO) with triangle waveform outputs. All LFOs share a common frequency control. Each of the LFOs 2, 3 features a Delta control which is used to shift the frequency of the LFO in question up or down. With the Delta controls at center positions the frequencies of all LFOs are roughly the same. To control the frequencies by external control voltages four CV inputs are available which follow roughly the 1V/oct standard.
The module has these controls and in/outputs available:
• Control F: manual control of the frequency for all four LFOs
• Control Delta F2, F3 and F4: manual control of the frequency shift up/down for the LFO in question
• Sockets CV 1...4: Frequency control voltage inputs (normalled from top to bottom)
• Sockets with triangle symbol 1...4: triangle outputs
• LEDs: visual displays of the triangle outputs (red = positive, yellow = negative output voltage)
