P2300/P2500/P2800 professional after-stage power amplifier
This machine adopts the whole iron 1.3mm stamping forming chassis and the whole board design mode of the power amplifier board. The whole machine is compact.
1) This machine adopts the whole iron 1.3mm stamping forming chassis and the whole board design mode of the power amplifier board. The whole machine is compact.
2) Use SEMIETH power amplifier tube for circuit current amplification to make the sound performance more transparent.
3) The AB design is used to make the sound soft, clear, and tolerant, and it can carry a lower impedance horn load.
4) Use professional audio capacitors to filter the rectified power supply to make the power supply ripple more clean, the output current is larger, and the load capacity is stronger.
5) Use the step potentiometer to make the consistency of the two channels better, and avoid the poor contact of the potentiometer after using for a period of time.
6) Add a limiter circuit to ensure that the power amplifier and speaker are effectively protected when there is an overload in the front stage.
7) Perfect output protection circuit with overcurrent, midpoint drift, overheat, undervoltage and soft start protection.
