BRZHIFI PA-1521 HiFi Audio Power Amplifier 220V 12W+12W 4-16ohms Classic TDA1521 Amplifier Chip for Philips

Description:
- The TDA1521 power amplifier adopts a dual power supply and independent separation design, greatly improving power output, high signal-to-noise ratio, higher separation, and more durable and pleasant sound, surpassing the LM1875. Its sound quality is unmatched by ordinary power amplifiers and digital power amplifiers of the same level.
- TDA1521 is a power amplifier chip for Philips with low distortion and high stability of digital audio playback. The sound quality used to connect the CD player for direct output is particularly good.

Features:
- The circuit is equipped with waiting and quiet states, with overheating protection, low offset voltage and high ripple suppression, and extremely low thermal resistance, with excellent high-frequency resolution and low-frequency force.
- The sound is transparent and pure, the bass is full and thick, and the treble is clear and bright, with a strong electronic tube flavor.
- The whole machine adopts high-power ring transformer power supply, high current rectifier bridge, and the choice of filtering capacitor for Nover for beautiful sound. The overall layout and wiring are reasonable and clear at a glance, with the chips placed at the bottom tightly against the chassis for heat dissipation. A unique design scheme that fully utilizes the chassis space and heat dissipation performance. The equipment can still maintain a low temperature and stable working state under high load operation.
- High power circular transformer with A-core pure copper wire winding without breakpoints.
