Product Details:
The power amplifier board has a reasonable design, high output power, strong bass, low distortion, low noise, high withstand voltage, mute switch, and over-temperature overload protection.
The power supply voltage range of the board is extremely wide, and it can work normally between DC dual +/-60V~110V.
In pursuit of clear sound quality! Pure sound! This power board removes the feedback capacitor DC feedback. The color has changed from the hazy feeling of the past, and the music is rich in details and strong! The input is processed by IC, and then pre-amplified by double differential high-frequency transistor circuit. The booster stage uses the original medium-power pair tube C4793/A1837 to drive a pair of Japanese original imported C5200/A1943, and then uses this pair of high-power pair tubes to drive 11 pairs. New Japan Toshiba imported large chip power tube C5200/A1943 or American ON Semiconductor NJW0302G/NJW0281G parallel output! Powerful! Suitable for high-fidelity home, stage industry power machine use.
