Class H STK419-110 HIFI Amplifier Board Thick Film 50W*2 High and Low Voltage Power Supply Assembled

Class H STK419-110 HIFI Amplifier Board Thick Film 50W*2 High and Low Voltage Power Supply Assembled

Description:
The power amplifier module STK419-110 series products adopt H-type power amplifier circuit with high and low voltage power supply. H-type chips have two sets of voltage power supply, high voltage and low voltage, and smooth switch automatically according to different output power. Class H power amplifier circuit is a relatively late product, and its design index puts forward high requirements for energy saving, signal-to-noise ratio, sound field and other indexes. This series of thick film chip features not only better design and production parameters, but also better listening sense. This amplifier can push the general bookshelf or floor speaker to achieve satisfactory results.

This board is designed in accordance with the concept of more fever, made of carefully selected material. You can can choose lie flat installation or vertical installation for the power amplifier module. It can achieve multi-channel function easier with the appropriate radiator. (The filter capacitance of this board is used disassembly product, the specification is 63V7000UF, the size is 35x35mm. There is not much filter capacitance of this size.

Voice performance: the overall timbre is warm, the voice is softer, the treble is extended higher but not harsh, the bass is deep enough and elastic, and it is not mixed and muddy. Sanyo thick film is between the integration and discrete amplifier between a circuit, fine workmanship and excellent technology than 3886, 7294 are better, the average DIY players are difficult to achieve this level.
