STA508 Amplifier Board (80W + 80W) STA508 TC2001 Surpass TA2024 TA2020
Introduction:
- STA508 10-35V single power supply 80W * 2 or 160W * 1 PWM signal input class-D amplifier, built-in mute , STBY; porphyrin porphyrin switch machine without sound , built-in short circuit, overheat , overload , over-current protection circuit , to meet smaller radiator environment. PO = 80W * 2 (Vcc = 35V THD = 10% f = 1khz RL = 8 Euro ) Po = 160W * 1 (Vcc = 35V THD = 10% f = 1khz RL = 4) PowerSO36
- Using original STA508 TC2001
- Electrolytic capacitor using220UF / 50V electrolytic Ensure strong support for a steady stream of power .
- Resistance selection 08,050,603 high precision chip resistors, ensure the machine a good signal to noise ratio.
- PCB1.6mm thick sheet using double-sided , 2.0 oz copper thickness , HASL whole process to ensure that the current size through good performance . PCB -class quality .
