The Shelter 411 II is mono-functional stereo MC transformer to match with MC cartridges with internal impedance (DCR) of less than 15 ohm. The impedance tolerance is 25 ohms. The transformer is a toroidal design that applies the toroidal winding to 0.05mm thickness of supermalloy, layered ring-core. The core volume has an external diameter of 25mm, internal diameter of 16mm and height of 10mm. The termination of the wire is directly connected to in/out terminal. Therefore, the high efficiency of the toroidal transformer has an extremely low loss structure. It delivers the signal from the cartridge without coloration to the phono-terminal directly. The Model 411II is a modified version of the original Model 411 and it has 32dB of step-up, a ratio of approximately 40 times.
