Features: The product is built using a genuine TDA7294. The front input capacitor and the inter-stage coupling capacitor use a top-level Siemens 2.2UF capacitor. The main circuit’s electrolytic capacitor signal adopts a popular Taiwanese brand, with a primary filter capacitor capacity of 4×4700UF. A rectifier flat bridge greater than 10A in use ensures robust continuing power support.
The device uses five-ring metal resistors, the core circuit employs a five-ring metal film resistor with an accuracy of ±1%. This maintains a superior signal-to-noise ratio for the entire machine.
The PCB design includes a 1.6mm thick double-sided board, complete with a 2.0 oz copper thickness. A full tin spraying process guarantees exceptional performance for both large and miniscule currents due to its high-quality PCB.
The all-aluminum chassis of this machine has undergone a wire drawing oxidation coloring process for an enhanced finish.
The entire circuit board presents a thorough and rational wiring layout, with the PCB wiring adopting a grounding point method.
This power amplifier board is stable, reliable and is capable of large output power. The sound it produces is attractive and has a wide range, providing a solid three-dimensional effect. It has a stable and powerful low frequency, superior signal-to-noise ratio, expansive dynamic range – all capitalizing on detailed clarity and excellent transient response. This makes it suitable to play any type of music, making a strong impression on any home sound environment.
