A preamplifier is basically a bunch of connectors, volume control and a buffercircuit. With the modules we present here, we provide these buffercircuits with a built in Voltage Controlled Amplifier (VCA) with exceptional wide ranges and with way lower tolerance than a regular potentiometer can do. Attenuation/gain can be set by a 0-4,8V dc voltage and/or by an SPI controlled dual DAC, depending on the model in 4096/1024/256 steps. By connecting a cheap DVM display module, the dB level can be read as well. All boards listed below are pin and size compatible.
These modules work "stand-alone" but can also be mounted on our Preamp modules.
