Product Description
Product Introduction
DM series power amplifier uses advanced Class-D power amplifier module and efficient and reliable R-SMPS stabilized power supply system, which can provide powerful and stable power within a 1U chassis; There's power factor correction technology (PFC) , The whole machine also has intelligent all-round electronic circuit high-speed protection and intelligent temperature control cooling system. Compared with traditional power amplifiers, its lightweight models and fresh and sweet sound are the best choice for large-scale sound reinforcement systems such as stadium, and outdoor mobile performances.
Product Advantages
1,1U chassis with compact volumn and light weight; It's convenient for transportation and mobile performances;
2,Class-D power amplifier module with integrated design, utilization rate of output power is as high as 93%;
3,With SMPS stabilized power supply system: soft switching mode with zero voltage and zero current, more stable operation and higher efficiency
4,Depends on Power factor correction technology (PFC), the power amplifier can adjust the current waveform according to the AC voltage waveform, the global wide voltage (90-264V) is adapted , and can meet the different needs of all users;
5,The intelligent temperature control stepless variable speed cooling system, perfect combination of high-density heat sink and fan, the speed of the fan is automatically adjusted by the temperature in the chassis, and the airflow flows from front to back, with a rapidly heat dissipation and efficient cooling.
6, Comprehensive electronic circuit intelligent protection:Soft start protection, DC protection, infrasound frequency, VHF, peak clipping, overheat protection, short termination, mute on/off.
7, Depending on high-efficiency speaker back-EMF absorption system, unique peak clipping limiter and ripple elimination network, the entire sound reinforcement system is more reliable, and the low frequency is strong and powerful, the dive is low, the MF &HF are transparent, clear and pleasant
8, The key components are imported brands, and more than 85% of the components adopt mechanical automation to ensure the consistency of the products.
