H series power amplifier

◎ H 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 damage.

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.
