professional sound system
◎Automatic AC soft-start protection at startup: Suppresses the starting current, does not affect the operation of other equipment and protects the internal circuit of the machine from impact.
◎It has a full-featured protection system, especially infinite overload protection, and can calmly face to the stereo 2 ohm load.
◎Delayed loading after startup: Protect the speaker from impact and start up silently.
◎DC output load protection: When the neutral point drifts and there is DC output, it can prevent the speaker from being damaged by impact.
◎Over-current automatic tracking output current-limiting soft protection: When the load impedance is too low and the input signal is over-excited, the power amplifier itself and the speaker are protected.
◎Clipping voltage limit protection: When the input signal is too large, it will make the power amplifier peak clipping distorted output, and it is easy to damage the speaker. This circuit can automatically detect the compression signal to protect the speaker.
◎Overheating protection: When the temperature of the power tube exceeds 80 degrees, the overheating protection automatically starts to cut off the load; when it is lower than 70 degrees, it automatically resumes work.
◎Load short-circuit protection: When the output is short-circuited, the short-circuit current is too large, the protection automatically cuts off the output, protects the power amplifier, and automatically recovers when the short-circuit is removed.
◎Shutdown protection: cut off the load when shutting down, to realize silent shutdown to protect speaker.
