Audio-Technica AT-SUT1000 MC Step-Up Transformer

The Audio-Technica AT-SUT1000 MC Step-Up Transformer boosts low-output moving coil cartridge signals before they reach a phono preamp. It supports 2 to 17 ohm MC cartridges, offers balanced or unbalanced connection options, and uses a hand-wound large-core transformer for high-fidelity analog playback.

Designed for serious vinyl systems, this Audio-Technica MC step-up transformer helps turntable owners preserve cartridge detail while gaining proper signal level. It is a strong choice for anyone looking to buy an MC step-up transformer, upgrade a moving coil cartridge setup, or improve a high-end phono signal chain.

The AT-SUT1000 uses HANENITE rubber mounting to suppress vibration and permalloy magnetic shielding to block external noise. Its transformer maintains a balanced signal from the moving coil cartridge through to the phono preamp, while RCA and XLR terminals support flexible system integration.
