P2800 Professional Power Amplifier
P2800 Professional Power Amplifier
Features:
▼ The machine uses full iron 1.3mm punching box with design of the full plate power amplifier board showing compact size
▼ Adopting SEMITH amplifier tube ensures circuit current amplification and more clear and powerful voice performance.
▼ AB type design makes the voice soft, clear and lasting. It even consists trumpet load with lower impedance
▼ The capacity is filtered by professional audio capacitor, making the power ripple more completely,the output current more strong, and loading more power.
▼ Marching typeof potentiometer to avoid the poor contact and ensure consistency of two channels all the better
▼ Built-in limited circuit to protect amplifier and speaker from input overload.
▼ Perfect protection circuits with the function of over current protection , midpoint drift protection, overheat protection, under voltage protection and soft start protection.
