With a refined electrical design and high-quality internal components, it provides clean, open sound across the full frequency range.\u003c\/p\u003e\n\u003cp\u003eThe ST-7 features a unique sandwich winding structure, which significantly improves high-frequency response, resulting in a detailed and airy presentation. Gold-plated terminals and high-quality internal wiring ensure optimal signal transmission with minimal loss.\u003c\/p\u003e\n\u003cp\u003eA true dual mono design, combined with individual shielding for each channel, enhances stereo imaging while reducing the impact of external noise. The use of permalloy shielding further protects signal integrity, helping maintain a quiet and controlled performance.\u003c\/p\u003e\n\u003cp\u003eCompatible with a wide range of moving coil cartridges, the ST-7 is particularly well suited to models such as the Ortofon MC Quintet Series, SPU Classic, and SPU #1. By boosting the signal from an MC cartridge to MM level, it provides increased output without introducing distortion or relying on additional gain from your amplifier.\u003c\/p\u003e\n\u003cp\u003eKey Features:\u003c\/p\u003e\n\u003cp\u003e• Compact and stylish design\u003cbr\u003e• High-performance moving coil step-up transformer\u003cbr\u003e• Sandwich winding structure for improved high-frequency response\u003cbr\u003e• Dual mono design for enhanced channel separation\u003cbr\u003e• Individual channel shielding for reduced noise\u003cbr\u003e• Permalloy shielding housing\u003cbr\u003e• Gold-plated terminals for optimal conductivity\u003cbr\u003e• High-quality internal wiring for signal integrity\u003cbr\u003e• Compatible with a wide range of MC cartridges\u003cbr\u003e• Particularly suited to Ortofon MC Quintet and SPU models\u003c\/p\u003e\n\u003cp\u003eTechnical Highlights:\u003c\/p\u003e\n\u003cp\u003e• Clear, open sound across the full frequency range\u003cbr\u003e• Improved stereo imaging and channel separation\u003cbr\u003e• Reduced environmental noise interference\u003cbr\u003e• Clean signal boost without added distortion\u003cbr\u003e• Efficient alternative to active MC phono stages\u003c\/p\u003e\n\u003cp\u003eSpecification:\u003c\/p\u003e\n\u003cp\u003e• Frequency Response: 15 – 45 kHz (+0 dB \/ -2.5 dB)\u003cbr\u003e• Gain: 24 dB (47 kΩ \/ 1 kHz)\u003cbr\u003e• Cartridge Impedance: 2 Ω – 60 Ω\u003cbr\u003e• Load Impedance: \u0026gt; 47 kΩ\u003cbr\u003e• Channel Balance: \u0026lt; 0.5 dB\u003cbr\u003e• Channel Separation: 70 dB (1 kHz)\u003cbr\u003e• Dimensions: 122 (W) x 43.5 (H) x 102 (D) mm\u003cbr\u003e• Depth including terminals: 113 mm\u003cbr\u003e• Weight: 0.79 kg\u003c\/p\u003e\n\u003cp\u003eWhat’s Included:\u003c\/p\u003e\n\u003cp\u003e• Ortofon ST-7 Transformer\u003cbr\u003e• Documentation\u003c\/p\u003e\n\u003cp\u003eNote:\u003c\/p\u003e\n\u003cp\u003eThis product is available for in-store demonstration.
