Description

Ortofon ST-7 Dual Mono MC Step-Up Transformer

Compact and stylish, the ST-7 has a solid housing supported by four rubber feet, which helps to reduce unwanted vibrations in the unit.

High quality internal wires together with high quality gold plated terminals provide the optimum signal transmission. The sandwich winding structure, used in the ST-7, significantly improves the high frequency response and provides a very clear and open sound over the whole frequency range.

Additionally, the dual-mono design, including the individual shielding of the two channels, improves the imaging of the transformer and reduces the influence of environmental noise.

The ST-7 transformer will be a perfect match for, among other MC cartridges, the MC Quintet Series and the SPU Classic models.

Features:

  • compact and stylish
  • sandwich winding structure
  • permalloy shielding housing for the left and right channels separately

Extract Max Performance From Your MC Cartridge or Add MC Capability to Your Phono Preamp With the Ortofon ST-7 Dual Mono MC Step-Up Transformer: Adds 24dB of Gain to Low-Output Cartridges

Drastically improve the sound of your MC phono cartridges and overall analog setup with the Ortofon ST-7 dual-mono MC step-up transformer. Intended for use with low-output (below 0.5mV) MC and MI cartridges, such as the Ortofon MC Quintet Series, ST-7 gives you an additional 24dB of gain while maintaining the quality of the original signal. The dual-mono ST-7 also significantly boosts the performance of your existing phono preamplifier via higher-quality internal wires, individual shielding of the left and right channels, and a sandwich-winding structure that enhances the high-frequency response and results in clear, open, airy sonics from the top to the bottom end. You’ll enjoy smoother, richer, more nuanced, and engagingly resolved playback from your vinyl LPs, as well as better drive and a remarkable reduction in grit, grain, and noise. Using an outboard step-up transformer like ST-7 also eliminates the need to use the preamplifier MM/MC push-button switch that degrades the signal quality. ST-7‘s compact dimensions mean it fits almost anywhere, while solid exterior housing and four rubber feet further eliminate vibrations.
