AM8110 VCO Announced
Description This is replica of the voltage controlled oscillator in the Roland SH-101* monophonic synthesizer introduced in 1984.
The AMSynths circuit is close to the original, using the advanced AS3340A oscillator chip, and with the original battery voltage rails converted to+/12V for Eurorack. High quality components have been selected, along with a few careful upgrades:
There are minature slide switches for;
The AMSynths circuit is close to the original, using the advanced AS3340A oscillator chip, and with the original battery voltage rails converted to+/12V for Eurorack. High quality components have been selected, along with a few careful upgrades:
- 1% polystyrene integrator capacitor
- Precision 5V voltage reference and Op Amps
- Fine tuning trimmer on front panel
- Minimum pulse width set at 5%
There are minature slide switches for;
- Pulse Width Modulation source (manual, external)
- Octave Range (8', 16', 32')
- Sub Oscillator (square at 1 or 2 octaves down, pulse at 2 octaves down)
