DS Audio E3 optical cartridge and phono

Uses a third-generation optical cartridge mechanism The DS-E3 uses a third-generation optical cartridge mechanism, the same design as our other products.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, improved channel separation, and the use of a beryllium light shielding plate. Aluminum cantilever with elliptical needle The cantilever is made of aluminum and the needle tip is a solid elliptical needle. While adopting the third-generation optical cartridge mechanism, the channel separation is set 1db lower to improve mass production efficiency. Equalizer New Amplification and Power Supply Circuits In the DS-E3 equalizer, the 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 amplifier The DS-E3 equa
