◎ P series power amplifier belonging to the fourth generation product design platform, They use a key patented technology, low-power K4 supply system,
it can bring nearly 85% music efficiency for the circuit,also reduce the system heat and size with 0.8w monotube. These products can integrated two pcs
of 2.4kW amplifier module in a 2U case.And just 20kg for the whole machine , which makes the H series professional power amplifier technology rise to the
top of the analog amplifier technology.
1.Perfect protection scheme to avoid the possible damage caused by misoperation and the embarrassing situation caused by false protection.The most
unique is the on-line load resistance detection, it can analyze system temperature to adjust the output accumulation power, high frequency energy
independent analysis and adjust HF output cumulative power.
2.Load impedance value detection technology, there is music as a detection signal, using real-time analysis of output voltage and current,the operation
result,if load resistance is lower than 3.2 ohm,it will instantly start soft protection limit power crystal drive current, the fault disappear within
10 milliseconds after restore output.During the process of the protection relay keep connection to avoid damage of contact, The technology also solve the
ultra-low frequency short out between channel.
3.When the system temperature over 45 °,the built-in fan will begin to gradually revolve until reach to 75 °.System temperature over 75 ° will CF
limit control system, gently improve the CF limiting value.At the moment, the average output power is slightly down, but the peak output power still can
remain.So dynamic will not damage and reduce the occurrence probability of anomalies.
4.Separate detect part of the signal voltage above 3 KHZ . When accumulated more than 40 v within 0.5 seconds,it will instantly start up the protection
system to reduce the output until the average less than 40 v.Also can reduce the abnormal situation in the process of using the high frequency drive
5.The radiators and transformer temperature are simultaneously detect, the output accumulates power continuously adjusted in stages.And the normal
output is maintained in the process of high temperature protection, the change of sound quality is very tiny.At the same time can continuously adjust the
cooling fan airflow speed to reduce system temperature.
6.The radiator dangling, power crystals and radiator directly stitching.Without traditional insulation layer, crystal can rapidly release the heat.It
can transfer heat without temperature difference.
