Features 3 AC coupled inputs 3 buffered outputs Input and output protection Protection against reverse PSU connection The buffered outputs allow you to send signals to several signal processing devices simultaneously, for example, split the output signal to LP and HP VCFs and create advanced bandpass and notch filters. Erica Black series are high-end modules with unique functionality. Only the highest quality components are used and all inputs and outputs are protected against undesired overvoltage. When designing the Black Series, they did not economise on the module width, they put design and usability first. Big knobs are assigned to functions that make difference in sound. Together the Erica Black series are a range of modules that make an entire synthesizer.
