Doepfer - A-110-2V: Basic VCO

Manufacturer Description: Module A-110-2 is a low-cost voltage-controlled oscillator. It's a slightly reduced version of the standard VCO A-110-1. Compared to the A-110-1 the A-110-2 has no sine output and the (expensive) octave rotary switch is replaced by a 3-position toggle switch. In return the A-110-2 is equipped with an additional linear FM input and a soft sync input. A jumper is used to select the range of the tune control between about 1/2 octave and about 4 octaves. The width of the module is only 8 HP compared to the 10 HP of the A-110-1.All other features are essentialy the same as for the A-110-1.Explanation of the jumpers and trimming potentiometers: JP2: CV connection to A-100 bus JP3: range of Tune control (installed = about 4 octaves, not installed = about 1/2 octave) JP4: AC/DC coupling of the linear FM input (installed = DC coupling, not installed = AC coupling) P5: 1V/Oct scale P6: frequency offset P7: high-end trim P8: adjustment +1 Oct. range switch P9: adjustment
