It is a low-distortion, low-noise amplifier that can precisely control the gain with a control voltage.
The voltage-controlled variable gain amplifier "VCA-1" is a 2-channel voltage-controlled amplifier using a transconductance variable method. It is a compact and user-friendly module that houses two channels in one case. The two VCAs can be used in series, allowing for a significant attenuation of 80dB to 100dB even at frequencies of several hundred kHz, which is difficult to achieve with a standard volume control.
