BRZHIFI Adopts STK4046V Circuit 200W High Power Split Single and Double Channel HIFI Power Amplifier Pure Post Stage

      STK4046~4048XI are the best models among Sanyo thick film, with delicate and balanced sound,
film flavor and analytical power. Any player who has played Sanyo thick film wants to get STK4048 the most,
but the STK4048 available on the market are all counterfeit products. The STK4046V module we got is a V-grade boxed
new stock, quality guaranteed and fulfill your dream when you were young.

     The sound produced by STK is thicker than that of transistor and tube amplifiers.
The thick film of STK4046 series performs better, and the high, medium and low frequencies are very
harmonious. You will not feel tired after listening for a long time. It is a typical representative of Japanese sound style.
The analog circuit structure has small sound coloration and distortion, balanced three-frequency, good extension
of high and low frequencies, strong control, and true sound field restoration, accurate positioning and phase combination, delicate, moist and durable.

      This machine adopts all-aluminum alloy precision CNC chassis, and adds a level meter power indicator.
It has a complete protection circuit and soft start control circuit. Each power amplifier uses a 400W imported iron
core pure copper wire precision ring transformer and 4 original American CDM 39000uF filter capacitors.
The coupling uses the Xinya Tianji series capacitors, and the high-frequency extension is very good. The genuine components ensure the circuit listening quality.

      Basic parameters 

• Product Name    :Split STK4046V power amplifier
• Rated Power    : 120W+120W  8Ω   200W+200W  4Ω
• Output Impedance    : 4~8Ω
• Frequency response range   : 10Hz~90kHz
• Distortion THD   : 0.08%
• Input sensitivity: 315mV
• Input Impedance  : 1KΩ

       Each amplifier uses a 400W imported iron core pure copper wire precision ring transformer,
and adds a bracket and shielding cover at the bottom of the transformer to further reduce the resonance and
interference caused by the transformer. The 400W ring transformer peak can handle the 200W rated output
power without restriction, and has a huge output current capacity to meet the large dynamic requirements of the equipment.

Each channel uses 4 American CDM-origin filter capacitors 39000uF/63V arrays with a total capacity of up to 156000uF.
The sound is better than the Philips series and the low-frequency density is very high.

       CDM is a well-established multinational company with a history of more than 100 years, with rich technology and experience.
Its capacitor products are selected by NASA for their excellent quality. CDM capacitors are made of excellent workmanship and materials,
with larger size and weight than Japanese capacitors, large current pins, and full weight. They perform well in products,
with good dynamics, moderate speed, thick sound base, and good sound layer extension.

      The coupling capacitors are from the Xinya Rose Gold Dimensity series developed for hifi audio,
which has excellent high-frequency extension and genuine components to ensure the circuit's listening quality.
In addition, the whole machine also has a complete protection circuit and soft-start control circuit.

All-aluminum alloy precision CNC chassis, added level meter power indication.

Certain analog-related assets include extensive process technology, analog design technology,
skilled analog engineers, and specially designed and manufactured excellent energy-saving and
environmentally friendly devices such as hybrid integrated circuits for inverters. SANYO
Semiconductor's core devices include discrete circuits, general-purpose analog large-scale
integrated circuits, ASSPs, and hybrid integrated circuits, which are widely used in a variety
of products such as personal computers, printers, cable TV, mobile phones, audio-visual equipment,
game equipment, car audio systems, and air conditioners.

    Sanyo STK is commonly known as Sanyo thick film. With the adjusted sound and high-precision semiconductor process control,
it is not a level that ordinary amateur DIY players can achieve. In addition to better sound field and resolution,
the low frequency is much stronger, which is completely the difference between professional athletes and ordinary players!
These thick film circuits have always been customized products for big brand audio manufacturers. In the early days,
many famous factories used them to manufacture power amplifiers, such as K + H, SONY, Panasonic P ANSONIC,
KENWOOD KENWOOD, JVC, SANSUI, SHARP, Pioneer PIO NEER, AIWA and almost all Japanese audio manufacturers chose them,
and they have been used for more than 20 years, affecting a whole generation.
It is also the sound with a strong imprint of the times that our whole generation heard when we were young.
Every time I hear it, I can't forget it. The company that Sanyo specialized in producing amplifier modules was
later acquired by ON Semiconductor of the United States. After the acquisition, the traditional craftsmanship of
Sanyo was integrated, and the unique design of ON was added. The later products were even more outstanding
and are still used by major American companies, such as BOSE and Genelec of Europe!
