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

【Important Notice for International Buyers – Tomoayax Premium Audio Hi-Fi Japan】

■ Voltage Compatibility This product is designed exclusively for use in Japan (AC 100V, 50/60Hz).

Many regions use 120V or 220–240V. Using this product without a proper transformer in such voltage environments may result in malfunction, overheating, or serious and irreversible damage.

■ Plug Type This product uses a Japanese plug (Type A or B). A plug adapter may be required depending on your region.

■ Transformer Requirement (Very Important) A transformer is required for safe use.

A plug adapter only changes the plug shape and DOES NOT convert voltage. Using this product without a transformer may cause serious and irreversible damage.

■ Buyer Responsibility As this is high-end audio equipment, the buyer is fully responsible for confirming compatibility with their local voltage (100V / 120V / 220–240V) and usage environment before purchase.

■ No Return / No Refund Policy We do NOT accept returns or refunds for: ・Voltage mismatch (including 120V and 220–240V environments) ・Use without a transformer ・Plug incompatibility ・Damage caused by improper setup or usage

■ Liability We are not responsible for any damage, malfunction, or performance issues caused by improper use or incorrect voltage conditions.

■ Final Notice Please ensure full understanding of the above before purchasing. Use only under the correct voltage environment. Equipped with STMicroelectronics' TDA7498E chip, high power MAX 160W + 160W By providing a gain setting DIP switch on the back of the unit, the gain setting can be easily changed. The coupling-less design using a DC servo circuit achieves a faithful and straightforward sound quality. By incorporating a speaker protection circuit, the speaker is protected from accidental DC leakage.

By eliminating the influence of coupling capacitors in the audio signal line on sound quality changes, it achieves a purer, more direct sound quality that is closer to the original sound. Furthermore, after generating the positive and negative power supplies, a power regulator stabilizes both the positive and negative power supplies, minimizing the noise floor. ■ Uses a small, high-current inductor specifically designed for digital amplifiers. A small, high-current-capable magnetically shielded inductor is used in the output filter section of the main amplifier IC located in the subsequent stage. This inductor has a significantly smaller volume compared to those used in conventional products, but because it uses flat copper wire, it can handle high currents. Because it has a larger surface area, the line impedance can be kept low, making it an inductor designed for audio applications. This significantly improved sound distortion, resulting in a noticeable improvement in sound quality, not only in the numerical values measured by audio analyzers but also in the audible sense. ■ Our commitment to key film capacitors Similarly, for the film capacitors, which also significantly affect sound quality, we have adopted capacitors that have a solid reputation for audio applications. All of these components are from manufacturers and series that are highly regarded for their Hi-Fi audio applications. Even within the same series from the same manufacturer, the sound quality can vary between current models. We take these factors into consideration when making our selections, utilizing vintage (NOS) items as well. ■ Equipped with speaker protection circuit The coupling capacitor-less design means there is no capacitor to protect against DC leakage, but a protection circuit is included to protect the speaker from any accidental DC leakage.
