SHELTER Model 411 Type II - MC transformer

Shelter Model 411 Type II – MC Step-Up Transformer

Pure analog gain with absolute signal integrity. The Shelter Model 411 Type II is a high-performance moving-coil step-up transformer designed to extract the finest musical detail from low-output MC cartridges. Handcrafted in Japan, it delivers noise-free gain, exceptional tonal purity and natural dynamics—preserving the soul of vinyl playback without active circuitry.

• High-quality MC step-up transformer for low-output cartridges
• Passive design with ultra-low noise and zero added coloration
• Handcrafted in Japan with precision-wound transformers
• Optimized for Shelter MC cartridges and reference analog systems

Product Overview

The Shelter Model 411 Type II is engineered to provide the ideal interface between low-output MC cartridges and MM phono stages. By using precision transformers instead of active gain, it amplifies fragile cartridge signals while maintaining purity, phase integrity and harmonic accuracy.

Its robust, resonance-controlled enclosure and carefully matched transformer windings ensure consistent performance and long-term reliability. The 411 Type II is a natural partner for high-end analog systems where transparency and musical flow are paramount.

Listening Experience

The 411 Type II delivers a quiet, spacious and organically dynamic presentation. Background noise is dramatically reduced, allowing micro-details, ambience and low-level textures to emerge naturally. Dynamics feel uncompressed and lifelike, with excellent transient response and tonal coherence.

Bass gains solidity and control, the midrange becomes more expressive and harmonically rich, and treble remains smooth and open—free from the glare sometimes associated with active MC stages.

Recommended Use

Ideal for low-output MC cartridges feeding high-quality MM phono stages. The 411 Type II is particularly well suited to Shelter cartridges, but also performs superbly with other MC designs of similar output and impedance.

Ideal Applications

• High-end vinyl playback systems
• Low-output MC cartridge installations
• Analog setups prioritizing purity and musical realism
• Systems seeking passive, noise-free gain before MM phono stages
