The STK4234MK2 power amplifier module has been discontinued, making it difficult to obtain authentic products on the market. Currently, stock availability is limited, so please act quickly if you intend to purchase!!!
The STK4234MK2 power amplifier module is a stereo HI-FI music power amplifier module released by Sanyo in 1998! It utilizes a highly advanced cross-flow circuit and paired high-power transistors internally, ensuring high-quality sound quality from the power amplifier! (Let's not talk about amateur situations. Even factories with a certain scale find it difficult to obtain paired high-precision power amplifier transistors in bulk under the current circumstances. Currently, our domestic audio industry struggles with these key components, so producing high-quality audio still poses some challenges.) This power amplifier module also incorporates a built-in speaker protection circuit that directly drives the output relay
From the parameter table, it can be seen that an 8 ohm load can achieve an actual output power of 100W x 2, with a distortion rate of 0.08%! It is also completely capable of driving 10-15 inch floor-standing speakers.
Sound performance: The overall tone is warm, the sound is relatively soft, the treble extends high without being harsh, the bass is deep and has good elasticity, without being muddy or dragging. The Sanyo thick film is a circuit that falls between integrated and discrete power amplifiers. Its fine craftsmanship and excellent technology surpass that of 3886 and 7294, and it is difficult for general DIY enthusiasts to achieve this level.
