Digital power amplifier equipped with TDA7498E FX-AUDIO- FX1002J+[Silver]

------------------------------------------------------------------------------------------------------------------ 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product 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. [Notes] -The power supply for this product is sold separately. A separate AC adapter is required for use. *Click here for recommended power supply https://www.amazon.co.jp/dp/B07MX18Y9Y?ref=myi_title_dp [Product specifications] Product warranty period: 6 months from the date of purchase Maximum output: 160W+160W / Compatible speakers: 4Ω ~ 16Ω Output terminal: 2ch stereo speaker output (gold-plated speaker terminal compatible with banana plugs) Input terminal: Stereo RCA terminal Digital amplifier IC: STMicroelectronics TDA7498E Function: Inrush current prevention function by delay muting relay/speaker protection circuit/SLOW CHARGING circuit Gain setting (23.6/29.6/33.1/35.6dB) back side DIP switch Power supply: DC19~32V Power capacity 2A or more (4A or more recommended) *Power supply sold separately Power connector: DC jack outer diameter 5.5mm x inner diameter 2.5mm (center plus specification) Accessories: Simple manual Size: Height 33mm x Width 96mm x Depth 168mm (excluding protrusions) Body weight: 530g *Specifications and design may change without notice due to improvements or other reasons.
