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 -1 Oct. range switch P10: temperature VCO heater
The core of the A-110-2 is - like the A-110-1 - a sawtooth oscillator (in contrast to the A-111-1, which is based on a triangle oscillator). The other waveforms are derived from the sawtooth by waveform converters. As the sawtooth reset (i.e. the back-to-zero slope) is not infinitely fast but takes a little bit of time the triangle is not perfect ! At the bottom of the waveform it has a small glitch or notch that is caused by the sawtooth reset and cannot be eliminated by the waveform converter. If a perfect triangle is required the A-111-1 is recommended.
The sawtooth output of the A-110-21 has a falling (or negative ) slope. The front panel shows erroneously a rising (or positive) slope. This has no influence to the sound but becomes important when the module is used as an LFO or is mixed with the sawtooth output of another VCO.
To obtain also a sine signal the triangle-to-sine converter module A-184-2 is recommended. It includes also a voltage controlled crossfader to fade between two waveforms.
Current: 150 mA (heat up period about 30 seconds), 60 mA (Long-term current)

These merchants probably sell this module. Huh?
