DS Audio DS-E3 Optical Phono System

Third-generation optical cartridge mechanismThe DS-E3 uses a third-generation optical cartridge mechanism, the same design as DS Audio’s other products. OVERVIEW The DS-E3 achieves an overwhelmingly low price while inheriting the merits of the third-generation mechanism, such as higher output due to independent LED and PD (photodiode), improved channel separation, and the use of a beryllium light shielding plate. FEATURES Aluminum cantilever with elliptical needleThe cantilever is made of aluminum, and the tip of the needle is a solid elliptical needle. While adopting the third-generation optical cartridge mechanism, the channel separation is set at 1 dB lower to improve mass production efficiency. THE EQUALIZERNew Amplification and Power Supply CircuitsThe DS-E3 equalizer's amplification circuit has been made symmetrical, and the voltage supplied to the cartridge has been stabilized to achieve a clearer and faster sound. Miniaturization is achieved by using an operational amplifierTh
