Uncompromising Power and Purity The Elex MK4 is engineered with a singular focus on musical performance. Its Class A/B power amplifier circuit, a refined version of Rega's proven designs, delivers a robust and dynamic performance. Great care has been taken in component selection, with the use of Sanken output transistors and high-quality relays to maintain a pristine signal path. A key feature of the Elex MK4 is the galvanic isolation between its digital and analogue sections, which eliminates interference and ensures a clean and transparent sound, whether you are listening to vinyl or a high-resolution digital file. A True Digital and Analogue Hub The Elex MK4 is a versatile hub for both analogue and digital sources. The integrated moving magnet phono stage is a high-quality circuit that provides the perfect interface for your turntable. For digital sources, the built-in DAC, based on the acclaimed Rega DAC-R, offers two digital inputs (one optical and one coaxial), allowing you to connect a CD player, music streamer, or TV. This blend of analogue and digital connectivity makes the Elex MK4 a flexible and convenient core for any modern hi-fi system. Meticulous Component Selection and Build Quality Rega’s commitment to quality is evident in every aspect of the Elex MK4. The circuitry is designed with discrete components and high-quality relays to ensure maximum signal integrity. High-grade polyester and polypropylene capacitors are used in the RIAA equalization stage of the phono circuit for superior accuracy. The new case design not only gives the amplifier a clean, modern look but also features improved heat dissipation to maintain optimal performance even under demanding conditions. Designed for Musical Enjoyment Every feature of the Elex MK4 is designed to enhance your musical enjoyment. The front-panel headphone output is a convenient addition for private listening. The amplifier also includes built-in protection features for thermal cut-out, short circuits, and DC protection, ensuring the safety and longevity of your unit. The result is an integrated amplifier that is not only powerful and versatile but also a pleasure to own and use, providing a truly engaging and musical listening experience.
