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

This integrated amplifier features the Texas Instruments TPA3116 digital amplifier IC, delivering up to 50W x 2-channel stereo output.

High-quality circuit design and artwork enable high-output and high-resolution sound at an affordable price.

The pre-amplifier circuit uses the Texas Instruments NE5532 audio-grade operational amplifier (DIP socket), which boasts excellent sound quality. Advanced users can enjoy customizing their sound by replacing the op-amp!

Product Features ■ Improved Sound Quality with Artwork Our unique circuit design and artwork achieve low noise and high separation.

■ Pre-amplifier Circuit with Op-Amp Uses the Texas Instruments NE5532 audio-grade operational amplifier (DIP socket). The sound quality is adjusted before the power amplifier IC, allowing advanced users to customize their sound by replacing the op-amp!

Note: Op-amp replacement is not covered by the warranty. *Op-amp drive voltage ≒ power supply voltage

■ Active filter installed in the op-amp IC power supply An active filter is installed in the op-amp power supply circuit, providing a clean power supply for improved sound quality.

■ Designed to unleash the potential of the digital amplifier IC and enhance sound quality Four bulk capacitors are placed around the TPA3116 digital amplifier IC to improve left-right separation and deliver clear, high-resolution sound. Low-ESR, low-impedance capacitors manufactured by Japanese manufacturers are used as bulk capacitors.

■ IC output filter component selection TDK power inductors are used for the inductors. Panasonic ECHU laminated metallized PPS film capacitors are used for the output filter, reducing harshness and delivering a pure sound. Other film capacitors are also used, providing excellent sound quality.

■ Input coupling capacitor component selection 85°C capacitors are used for the input coupling capacitor to the front-stage op-amp. TDK EPCOS film capacitors are used for the input coupling capacitor to the digital amplifier IC.

■MCU-Controlled Pop-Noise Prevention Circuit By using an MCU program to control the output delay at power amplifier IC startup, pop noise is suppressed while eliminating the need for an output control relay.

[Notes] - This product requires a separate power supply. A separate AC adapter is required for use.
