    The STK4234MK2 power amplifier module is a stereo HI-FI music power amplifier module released by Sanyo in 1998! The internal use of a very feverish cross-flow circuit and a paired high-power transistor, the high-quality sound quality of the power amplifier! (Now let's not talk about amateur situations, even if there are factories of a certain scale, it is difficult to get high-pairing power amplifier triodes in batches under the current circumstances. At present, our domestic audio industry is mainly concerned with these key components, so it is still difficult to make sound). This power amplifier module also comes with a speaker protection circuit to directly drive the output relay  

As can be seen from the parameter table, the actual output power of 100WX2 can be obtained with an 8-ohm load, and the distortion rate is 0.08%! There is no problem in pushing 10-15 inch floor-to-ceiling speakers.

          Sound performance: The overall tone is warm, the sound is relatively soft, the treble extension is high but not harsh, the bass is deep enough and elastic, and it will not be mixed or sloppy. Sanyo thick film is a circuit between integrated and discrete power amplifiers. Fine workmanship and excellent craftsmanship are stronger than 3886 and 7294, and it is difficult for general DIY players to achieve this level.

The original Sanyo STK4234MK2 thick film module, the measured power is as high as 100W 8 Europe * 2 channels, and the thrust is strong 5-15 inches.

300W full power toroidal A-core pure copper wire transformer

The original Japanese ALPS blue molded case volume potentiometer is used more in mid-to-high-end fever power amplifiers, which has obvious advantages and characteristics compared with ordinary volume potentiometers. Ordinary potentiometers will generate noises such as "squeaking" when adjusting the volume, and the left and right volume balance is not very ideal. It is easy to introduce noise, has poor resistance to harsh environments, is easy to have poor contact, and causes large rotation noise and many other problems, which are difficult to accept and even scare users (the speaker emits a loud abnormal sound). The ALPS potentiometer overcomes these problems and has stable performance for a long time
