Detail
Perfect the precise protection scheme to avoid the embarrassment caused by mistake operation and damage. The most unique is the on-line load resistance detection, detection and analysis of the system temperature to adjust the output accumulative power and high frequency energy to analyze and adjust the high frequency output accumulative power alone.Load impedance constant value detection technology, using the music being played as the detection signal, real-time analysis of the output voltage and current, operation to get the online load resistance results, lower than 3.2ohm to start the soft protection limited power crystal drive current, after the failure disappeared within 10 milliseconds to restore output, relay protection relays remain in the process. Connection, avoid contact damage, this technology also solves the problem of inter channel low frequency short circuit reliability.
When the system temperature exceeds 45 degrees, the built-in fan starts to accelerate gradually and reaches the highest wind force at 75 degrees.
When the system temperature exceeds 75 degrees, the "peak factor (CF) limit value control" system is started, and the CF limit is raised gently. At this time, the average output power will decrease slightly, but the peak output power can still be kept, the dynamics will not be damaged and the abnormal conditions such as "cold field" will be reduced.
The signal voltage of more than 3kHz in the output signal of the output signal is detected separately, 0.5 seconds accumulates more than the 40V instant start protection system, and reduces the output to an average of less than 40V, and reduces the damage to the high tone driver in the use process.
The temperature of the radiator and the transformer is detected at the same time, and the output accumulative power is continuously adjusted in stages. In the process of high temperature protection, the normal output is maintained, and the sound quality is fine and difficult to be detected. Meanwhile, continuously adjust the airflow speed of the cooling fan to reduce the system temperature.
DC output protection, detect DC components in the signal, cut off the output when it is too high, protect the loudspeaker from damage.
