About Sanyo Semiconductor (a member company of ON Semiconductor)
Sanyo Semiconductor Co., Ltd. (a member company of ON Semiconductor) is a semiconductor manufacturing company with excellent power device technology, such as small packaging technology, high energy efficiency switching technology, high density packaging technology, etc., as well as the world’s YI flow simulation technology. Several simulation-related assets include a wide range of process technology, simulation design technology, skilled simulation engineers, and specially designed and manufactured excellent energy-saving and environmentally friendly devices, such as hybrid integrated circuits for inverters. The core devices of Sanyo Semiconductor include discrete circuits, general-purpose analog large-scale integrated circuits, ASSP and hybrid integrated circuits, which are widely used in various products such as personal computers, printers, cable TV, mobile phones, audio-visual equipment, game equipment, car audio Systems and air conditioning.
Sanyo STK is commonly known as Sanyo Thick Film. Under the control of the adjusted sound and high-precision semiconductor process production process, it is not a level that ordinary amateur DIY players can achieve. In addition to better sound field and resolution, the low-frequency strength is much stronger, which is the difference between professional athletes and ordinary players! These thick-film circuits are always customized products for large-scale audio manufacturers. Many well-known factories in the early days used them to make power amplifiers, such as K+H, Sony SONY, Panasonic PANSONIC, Kenwood KENWOOD, JV JVC, Shanshui SANSUI, Sharp SHARP, Pioneer PIONEER, Aiwa AIWA, etc. Almost all Japanese audio It has been selected by manufacturers and has been in use for more than two decades. It has influenced a whole generation, and it is also the voice with strong brand of the times that we have heard for a whole generation when we were young. It is unforgettable every time it sounds. Sanyo’s company specializing in the production of power amplifier modules was later acquired by ON Semiconductor of the United States. After the acquisition, it integrated Sanyo’s traditional processes, coupled with ON’s unique design, the later products are more outstanding, and it is still used by large companies in the United States. , Such as BOSE, such as the European Genelec!
Fortunately, I met the early SANYO power amplifier module STK443, which is the most powerful model in this series. The early product design was quite satisfactory. The tuning was done according to the listening style of the tube era. The field effect tube input amplifier circuit of this module is warm. Delicate and unique. The design output power is 25W+25W @8 ohm, and the distortion THD is 0.3%. This thick film chip was only customized by SONY products at that time, so it was hard to see on the market.
This machine is designed for listening to music on home computers, and it is easy to use with portable devices with Bluetooth function. The casing of the whole machine is made of CNC all-aluminum alloy, and the retro-designed warm-light dual-header adds a touch of atmosphere to music listening. The appearance of the whole machine is exquisite and compact, which is convenient for placing on the computer desktop.
