CA TDA7498 2.1 digital power amplifier board (200W+100W+100W) Super TPA3116

Description:

n The original TDA7498 TL072

n Pre input capacitance and coupling capacitance using Siemens 1uF top capacitor, electrolytic capacitor signal the main circuit by the Taiwan famous brand, the main filter capacitor by Japanese Panasonic special electrolytic capacitor capacity of 2 * 2200UF, which support the strength of endless power.

n Resistance selection of high precision chip resistors, the main circuit uses five metal film resistor precision + 1%, the signal-to-noise ratio of the good.

n PCB with 1.6mm thick double-sided board, 2 oz copper thickness, tin spraying the whole process, ensure the size of the current good through the performance. PCB class quality.

n The fully enclosed dust-proof potentiometer, the performance is more stable, and more durable than ordinary potentiometer.

n The red ring high current inductor, ensure sound crisp and powerful.
