The high-quality circuit design and artwork make it possible to achieve both high output and high-resolution sound quality at an affordable price. The front stage amplifier circuit uses the Texas Instruments audio operational amplifier "NE5532" (DIP socket type), which has high performance in terms of sound quality, and advanced users can enjoy getting closer to their desired sound quality by replacing the operational amplifier! [Product features] ■Improvement of sound quality through artwork Low noise and high separation are achieved through circuit design and artwork based on unique know-how. ■Pre-stage amplification circuit using operational amplifier Adopts Texas Instruments' audio operational amplifier "NE5532" (DIP socket type). The sound quality is adjusted before the power amplifier IC, so advanced users can enjoy getting closer to their desired sound quality by replacing the operational amplifier! *Replacing the operational amplifier is not covered by the warranty. *Op amp drive voltage ≒ power supply voltage ■Equipped with an active filter in the operational amplifier IC power supply An active filter is configured in the power supply circuit to the operational amplifier to improve sound quality by supplying clean power. ■Designed to bring out the potential of digital amplifier IC and improve sound quality By placing four bulk capacitors around the digital amplifier IC "TPA3116", left and right separation is improved, resulting in clear, high-resolution sound quality. A low ESR/low impedance capacitor made by a Japanese manufacturer is used as the bulk capacitor. ■IC output filter component selection A TDK power inductor is used as the inductor. By using Panasonic's laminated metallized PPS film capacitor ECHU as the output filter, the sound quality is suppressed from roughness, resulting in pure sound. In addition, film capacitors are also used, which are superior in improving sound quality. ■Input coupling capacitor component selection An 85 degree capacitor is used as the input coupling capacitor to the front stage operational amplifier. TDK EPCOS film capacitors are used as input coupling capacitors to the digital amplifier IC. ■Pop noise prevention circuit controlled by MCU By controlling the output delay when the power amplifier IC starts up using the MCU program, it is possible to eliminate the need for an output control relay while suppressing pop noise. [Notes] ・This product is sold separately. A separate AC adapter is required for use.
