The Ortofon T-30 is a compact step-up transformer designed for use with moving coil (MC) cartridges in audio setups. It enhances the output signal from the cartridge, allowing for improved performance when connected to a standard moving magnet (MM) phono stage. The T-30 features high-quality components and is built to minimize noise and distortion, thus preserving the integrity of the audio signal. It typically includes both 1:10 and 1:20 step-up gain options, allowing users to select the appropriate gain to match their specific cartridge and system requirements. The transformer is designed with a focus on low-frequency response, providing a balanced and dynamic sound without coloration. Its compact size makes it suitable for various audio setups, whether for home use or in professional environments.
