SOT Series of Signal Audio Transformers was designed to meet excellent electrical&mechanical performances with top-end sonic results. An high bandwidth (8Hz..130kHz typically) along with a low linear and non-linear distortion have been obtained with a laminated mu-metal core. SOT Series come also with a mu-metal case for top results in hostile environments as mixed-signal boards. Shielding between each layer reduce dramatically the noise due to capacitive coupling .
