The ES 2164 VCA is a 4hp linear, dual channel VCA. It uses the 2164 submodule to provide two independent channels of high fidelity, low noise amplification of audio or CV signals. Each channel has a dedicated offset knob that becomes an attenuator when CV is present. In addition, channel one normals down to channel two when no signal is inserted to allow for multiple amplifications of a single source without repatching.
