Dual Quantizer module. Two discrete circuits, functionally independent and identical. Converts continuous signal to DC step output voltage conforming to typical musical scales. Fast sample acquisition time, resulting in excellent response/ conversion with no audible slew. Zero Droop design.
Note Regarding Power Consumption:
In testing with a Rigol DP832 power supply I'm getting different values then previously posted and in measuring the two different copies I have here they are not the same either. (the older one is reading higher than the newer one). For what it's worth I'm going to make notes here on the previously reported values and the values I'm measuring.

These merchants probably sell this module. Huh?
