D series high quality 4 channel Stereo digital power amplifier from China

Product Characteristic from GYIMPEX AUDIO CHINA FACTORY  :
1) 1U height 9 "width of standard cabinet, compact size, lightweight and portable； 
2) ClassD power module with fixed switching frequency； 
3) The soft start LLC resonant SMPS module； 
4) The active power factor correction (PFC), can be stable working in full voltage range (90-264V)； 
5) The efficient speaker EMF absorption system； 
6)The unique peak limiter and ripple cancellation network； 
7) The fan with temperature control and variable speed, airflow from front to rear； 
8) Connection mode selection (stereo / parallel / bridge)； 
9) Input sensitivity switch (0.775v/1v/32dB)； 
10) The whole circuit protection, including: soft start, DC, infrasonic frequency, VHF, overheat, short circuit, mute on / off； 
11) The low frequency powerful, depth is extremely low, mid high frequency with high transparent, clear and sweet； 
12) The integration design of the power amplifier module and power supply module, more than 85% components with mechanical automation operation, to ensure the consistency of the product；
13)In conclusion, power amplifiers that use PFC present several benefits over those that don’t. PFC helps to reduce costs by pulling less reactive power, increase acceptable voltage range to ensure universally clean operation around the world, and reduce unwanted distortion for friendly and clean power.

13) Applications : The touring / portable audio performance；  The KTV/ bar / Music Hall； The stadium / arena；
