FX-AUDIO- FX-502J PRO TDA7498-equipped 50W x 2ch Integrated Amplifier with Tone Control Function (Silver)

Introducing FX-AUDIO-'s first mid-range integrated amplifier with tone control functionality!

【Product Features】 ■ High-Quality Sound Through Artwork Low noise and high separation are achieved through circuit design and artwork based on unique know-how.

■ Pre-amplification Circuit with Op-Amp Uses Texas Instruments' audio-grade op-amp "NE5532" (DIP socket type). The sound quality is adjusted in the pre-amplifier stage, and advanced users can enjoy customizing the sound by replacing the op-amp!

■ First Tone Control Circuit in FX-AUDIO- Mid-Range Products A tone control circuit (negative feedback type), which was frequently requested in mid-range models, is now included, achieving both convenience and sound quality. Similar to the pre-amplification section, it uses Texas Instruments' audio-grade op-amp "NE5532" (DIP socket type), allowing for sound quality adjustment by replacing the op-amp in this circuit as well.

■ Active Filter in the Op-Amp IC Power Supply An active filter is incorporated into the power supply circuit to the op-amp, ensuring a clean power supply and improved sound quality.

■ High Sound Quality Through Efficient Bulk Capacitor Placement A large-capacity 8100μF W-series capacitor from Nippon Chemi-Con is used for the power supply smoothing capacitor. Combined with the ELNA RE3 (85℃) 330μF capacitor placed directly next to the digital amplifier IC "TDA7498," this achieves a smooth, extended sound quality without loss of tone even at high volumes.

■ Carefully Selected Components ELNA audio-grade 85℃ capacitors are used for the input coupling capacitors to the pre-amp, and TDK EPCOS film capacitors are used for the digital amplifier IC input coupling capacitors.

On the output side, TDK power inductors (a standard in digital amplifiers) are used, along with the highly regarded TDK EPCOS film capacitors and Arcotronics/AV R82 63V/0.22μF (Made in Italy) metallized film capacitors for the output filter, etc.

From input to output, we've employed components renowned for their sound quality and stability, resulting in an uncompromisingly high-quality sound.

■Aluminum Alloy Body The brushed aluminum body and machined front panel create a luxurious and substantial presence.
