integrated amplifier with TPA3116 FX-AUDIO- FX-502J [Silver] 50W×2ch

---------------------------------------------------------------------- 【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. ----------------------------------------------------------------------

AC adapter required (sold separately) DC12~24V/2A DC jack 5.5mm x 2.5mm (center positive) Equipped with TPA3116 High quality sound with artwork Large capacity power supply decoupling capacitor Equipped with an active filter in the operational amplifier IC power supply This product is an integrated amplifier equipped with the "TPA3116" digital amplifier IC manufactured by Texas Instruments and capable of maximum 50W x 2ch stereo output. With high-quality circuit design and artwork, we have achieved both output and high-quality sound at an affordable price. The front stage amplifier circuit uses Texas Instruments' audio operational amplifier "NE5532" (DIP socket type), which has high cost performance in terms of sound quality, and advanced users can enjoy getting closer to their desired sound quality by replacing the operational amplifier! [Product features] ■Higher sound quality with artwork Low noise and high separation are achieved through circuit design and artwork based on unique know-how. ■Pre-stage amplification circuit using operational amplifier Adopts Texas Instruments audio operational amplifier "NE5532" (DIP socket type). The sound quality is adjusted before the power amplifier IC, so advanced users can enjoy getting closer to their desired sound quality by replacing the operational amplifier! *Replacing the operational amplifier is not covered by the warranty. *Op amp drive voltage ≒ power supply voltage ■Equipped with an active filter in the operational amplifier IC power supply An active filter is configured in the power supply circuit to the operational amplifier, and high quality sound is achieved by supplying clean power. ■Higher sound quality of digital amplifier IC Four bulk capacitors are placed around the digital amplifier IC "TPA3116" to improve left and right separation and achieve high sound quality. A low ESR/low impedance capacitor made by a Japanese manufacturer is used as the bulk capacitor. ■IC output filter component selection A TDK power inductor is used as the inductor. By using Panasonic's laminated metallized PPS film capacitor ECHU as the output filter, the sound quality is suppressed from roughness, resulting in pure sound. In addition, high-quality film capacitors are also used. ■Input coupling capacitor component selection An 85 degree capacitor is used as the input coupling capacitor to the front stage operational amplifier. TDK EPCOS film capacitors are used as input coupling capacitors to the digital amplifier IC. ■Pop noise prevention circuit controlled by MCU By controlling the output delay when the power amplifier IC starts up using the MCU program, it is possible to eliminate the need for an output control relay while suppressing pop noise. We have adopted a high-quality sound design that minimizes deterioration in sound quality. [Notes] -The power supply for this product is sold separately. A separate AC adapter is required for use.
