Detailed Product Description
Power Amplifier
- 250W monophonic constant-voltage audio power amplifier, high-power Darlinton triode parallel push-pull output, high-power over measure, high reliability.
- Use of digital logic control of technology, touch key, easy and simple and visualized operation.
- 32-grade digital control of volume, abrasion free, super long life, volume storage and memory, automatic value assignment at startup.
- LED bar display meter for volume and output level.
- High-speed-response latching output overloads protection, output short circuit protection, and automatic restoration.
- Protective circuits for input over voltage and output over voltage effectively protect the power amplifier from damage by accidental operation.
- Output protection for time delay of startup.
- AC220V or DC 24V power supply, automatically switching to DC power supply when there is a failure or under voltage of AC. Under voltage and over voltage protection.
- Heat radiation with a large radiator, providing over heating protection function.
- Overload display lamp, alarm display lamp, sending signals to the interlocking controller when an alarm is given.
- Externally controlled startup port, automatic power up, interlocked voice alarm broadcast.
- Output by constant voltage 120V.
