It maintains the core performance principles that define Grado cartridges while offering broad system compatibility.\u003c\/p\u003e\n\u003cp\u003eUtilizing Grado’s moving iron design, Red4 provides a stable and consistent signal with low moving mass and long-term reliability. The die-injection molded housing supports consistent construction and dependable performance.\u003c\/p\u003e\n\u003cp\u003eOffered in both standard mount and P-mount configurations, Red4 is designed for a wide range of systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePerformance\u003c\/strong\u003e\u003cbr\u003eRed4 is a high output moving iron cartridge designed for compatibility with a wide range of phono stages.\u003c\/p\u003e\n\u003cp\u003eIts presentation is balanced and controlled, with clear detail and a smooth, natural top end. The midrange carries presence and body, while low frequencies remain defined and composed.\u003c\/p\u003e\n\u003cp\u003eRecordings are presented with stability and coherence, maintaining separation and imaging while allowing the character of the music to come through naturally.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDiamond, Cantilever \u0026amp; Stylus\u003c\/strong\u003e\u003cbr\u003eRed4 features a bonded elliptical diamond mounted to an aluminum cantilever.\u003c\/p\u003e\n\u003cp\u003eThe elliptical profile provides effective groove contact and reliable tracking, while the aluminum cantilever contributes to a stable and controlled presentation. This combination delivers clarity and consistency across a wide range of recordings.\u003c\/p\u003e\n\u003cp\u003eThe stylus assembly is user-replaceable, allowing for easy maintenance and long-term ownership. All Prestige Series styli are interchangeable, providing flexibility across models while maintaining consistent performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMoving Iron Design\u003c\/strong\u003e\u003cbr\u003eAll Grado cartridges utilize a moving iron design built on Joseph Grado’s patented flux-bridger principle.\u003c\/p\u003e\n\u003cp\u003eThis approach allows the cartridge to generate a precise signal with extremely low moving mass, while keeping the coil structure fixed. The result is a presentation that combines speed, control, and harmonic integrity without the fragility often associated with traditional moving coil systems.\u003c\/p\u003e\n\u003cp\u003eThe design also ensures long-term consistency, maintaining performance over time without degradation of the internal signal path.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCoil \u0026amp; Internal Structure\u003c\/strong\u003e\u003cbr\u003eThe internal signal path is built using ultra-high purity 5N OCC copper, selected for its conductivity and consistency.\u003c\/p\u003e\n\u003cp\u003eEach cartridge undergoes cryogenic treatment and internal damping to reduce unwanted resonance and preserve signal integrity. The result is a presentation that remains coherent, balanced, and dynamically responsive.\u003c\/p\u003e","brand":"Grado","offers":[{"title":"1\/2\" Mount","offer_id":43847444955270,"sku":"GRADO.RED4","price":289.0,"currency_code":"AUD","in_stock":true},{"title":"P Mount","offer_id":43847444988038,"sku":"GRADO.P.RED4","price":289.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0875\/3864\/files\/grado-red4-cartridge-lifestyle.jpg?v=1775738172","url":"https:\/\/addictedtoaudio.com.au\/products\/grado-red4-cartridge","provider":"Addicted To Audio","version":"1.0","type":"link"}
