Linear VCAs based on a discrete OTA core
The ADE-50 provides 3 all-analogue voltage controlled amplifiers based on a modern operational transconductance amplifier design.
The VCAs are designed to provide a good balance between the performance and specification of modern ‘on-chip’ VCAs and the character and musicality of classic analogue designs.
The OTA core of each VCA is fully discrete - it is built from only resistors, capacitors and transistors - however, the CV conditioning, audio input and output stages are built using high-quality op-amps giving the best balance between musicality, character and performance.
The ADE-50 provides a good signal-to-noise ratio, linearity, attenuation, an output level at unity gain at 5V CV input, minimal CV ‘bleed’ and minimal output offset/bias.
