TPA3116 50W x 2ch Integrated Amplifier FX-AUDIO- FX-502J [Black]

---------------------------------------------------------------------- 【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): DC 12-24V/2A, DC jack 5.5mm x 2.5mm (center positive) Equipped with TPA3116 High-quality sound through artwork Large capacity power supply decoupling capacitor Equipped with an active filter for the power supply of the operational amplifier IC This product is a pre-main amplifier equipped with the Texas Instruments "TPA3116" digital amplifier IC, which enables a maximum of 50W x 2ch stereo output. Thanks to its high-quality circuit design and artwork, it combines high output and high-resolution sound quality at an affordable price. The pre-amplification circuit uses the Texas Instruments audio op-amp "NE5532" (DIP socket type), which has high performance in terms of sound quality. Advanced users can enjoy changing the op-amp to get closer to their preferred sound quality! [Product Features] ■ Artwork improves sound quality Circuit design and artwork based on our unique know-how achieve low noise and high separation. ■ Pre-amplifier circuit using an operational amplifier Uses the Texas Instruments audio operational amplifier "NE5532" (DIP socket type). The sound quality is adjusted before the power amplifier IC, so advanced users can enjoy changing the op-amp to get closer to their preferred sound quality! *Replacing the operational amplifier is not covered by the warranty. *Op-amp drive voltage ≒ power supply voltage ■An active filter is installed in the power supply of the operational amplifier IC An active filter is configured in the power supply circuit to the operational amplifier, providing a clean power supply and improving sound quality. ■Designed to bring out the potential of digital amplifier ICs and improve sound quality By placing four bulk capacitors around the digital amplifier IC "TPA3116", left and right separation is improved, resulting in clear, high-resolution sound quality. Low ESR, low impedance capacitors made by Japanese manufacturers are used as bulk capacitors. ■Selecting components for IC output filters TDK power inductors are used. By using Panasonic's laminated metallized PPS film capacitor ECHU for the output filter, roughness in the sound quality is suppressed, resulting in a pure sound. In addition, film capacitors are also used, which are advantageous in improving sound quality. ■Selecting input coupling capacitor components An 85° 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. ■MCU-controlled pop noise prevention circuit By using an MCU program to control the output delay when the power amplifier IC starts up, we have achieved the elimination of the output control relay while suppressing pop noise. [Notes] ・This product requires a power supply sold separately. A separate AC adapter is required for use.
