Roland 530 Dual VCA

Based on the classic SYSTEM-100M modular synthesizer, the SYSTEM-500 is a fully analog recreation of one of the most revered electronic instruments of all time. Newly designed in Eurorack format, the SYSTEM-500 delivers the classic character and functionality of the original with the advantages of a modern instrument. The SYSTEM-500 is made to exacting standards with top-quality components and solid controls, with a collaborative production process between Portland, USA and Hamamatsu, Japan.
The 530 Dual VCA (voltage controlled Amplifier) features two independent voltage controlled amplifiers for controlling the loudness of audio signals. Each VCA has three sliders for an audio input mixer, three sliders to mix CV inputs, and a selector switch for linear or exponential response modes.
