Employing the finest materials and production methods, the AT-SUT1000 MC step-up transformer is built to deliver unaltered sound from a moving coil phono cartridge for the best analog listening experience possible. It features a special hand-wound, large-core transformer that is capable of a wide range of voltages, making it ideal for stepping up low-impedance moving coil cartridges. The transformer maintains a balanced signal from the moving-coil cartridge through to the phono preamp. Or users can opt for an unbalanced connection, if desired. The AT-SUT1000 utilizes HANENITE rubber mounting to suppress vibrations and permalloy magnetic shielding to block external noise.
