Digital Power Amplifier Equipped with TDA7498E FX-AUDIO- FX1002J+ [Black]

------------------------------------------------------------------------------------------------------------------ 【Cautions for using electrical products】 When using electrical appliances, please note that the voltage is different from that of Japan, which may cause malfunctions. Since the plug type is Japan type(A or B type), please check the voltage and use a transformer. (This product does not include a transformer.) Please note that a transformer is different from a conversion adapter. We are not responsible for malfunctions caused by use without a transformer. ------------------------------------------------------------------------------------------------------------------ Equipped with “TDA7498E” manufactured by STMicroelectronics High power MAX160W+160W Gain settings can be easily changed by providing a gain setting DIP switch on the back of the main unit. Coupling-less design with DC servo circuit, achieving straight sound quality that is faithful to the original sound Equipped with a speaker protection circuit to protect the speaker from any DC leakage. AC adapter required (sold separately) DC19~32V/2A DC jack 5.5mm x 2.5mm (center positive) [Product features] ■High power (160W) The high power digital amplifier IC "TDA7498E" achieves a maximum output of 160W + 160W. ■Coupling capacitor-less design with active DC servo circuit Active DC servo circuit eliminates input coupling. This eliminates the effects of changes in sound quality caused by coupling capacitors installed in the audio signal line, achieving pure and straight sound quality that is closer to the original sound. Moreover, after generating positive and negative power supplies, both ± power supplies are stabilized by a power supply regulator, and the noise floor is attenuated as much as possible. ■Uses a small, high-current inductor specifically designed for digital amplifiers. A small magnetically shielded inductor that can handle high current is used in the output filter section of the main amplifier IC located at the rear stage. The volume of this inductor is significantly smaller than that used in conventional products, but since it uses flat type copper wire, it can handle large currents. The line impedance is kept low due to the large surface area, making it an inductor designed to be suitable for audio applications. As a result, the distortion of the sound has been significantly improved, and the sound quality has been improved to the extent that it can be heard visually, as can be seen in the numbers measured with an audio analyzer. ■Commitment to major film capacitors The film capacitor, which also has a large effect on sound quality, is a capacitor with a reputation for audio use. All products are from manufacturers and series model numbers that are highly rated for Hi-Fi audio use. Current products from the same series from the same manufacturer may have different sound quality, so we make full use of vintage (NOS products) and other items to make a comprehensive selection. ■Equipped with speaker protection circuit Due to the coupling capacitor-less design, there is no capacitor to protect against DC leakage, but the built-in protection circuit protects the speaker from any DC leakage.
