Signal Summer


The Signal Summer is a versatile three-channel signal mixer with input weighting and channel inversion on two of the three input channels. Input channels A and B are independently scaled then summed along with input C to produce the final output. A precision active summing circuit is used to give the SM5 quiet and accurate adding performance. The SM5 has very low noise and a flat frequency response up to 200 kHz.
