Outdoor audio equipment
Model: D350
D series digital power amplifier and other products of commercial series are integrated and unified solutions, which are applied to commercial places such as large shopping malls, conference halls, transportation hubs and so on.
·It is designed with international advanced high-efficiency switching power supply (SMPS) and class D power amplification circuit (Class D);
·The designed porous heat sink can operate normally at low temperature in various harsh environments;

·The switching power transformer adopts imported Teflon high temperature line to ensure that the transformer can work normally and efficiently at high temperature.
·Built in a variety of sensitivity and compression modes to choose from.
·Built in digital audio processor function.
·Full set of protection functions to ensure the orderly operation of the product:
1. Power intelligent constant technology: when the connected load of the power amplifier is lower than the rated range, the output power is intelligently controlled and will not continue to increase. It is constant in the safe and reliable working range, which greatly improves the stability of the power amplifier.
2. Resonant soft switching technology: specially designed for professional power amplifiers with high quality and high requirements, also known as zero voltage on and zero voltage off technology, to eliminate di / dt impact caused by conventional power switches.
3. High density heat dissipation technology: the unique constant temperature intelligent temperature regulation circuit, coupled with the high-density aluminum radiator used in aviation, can easily reduce the working temperature of the machine to the bottom and ensure the high stability of the machine.
4. Tunnel cooling technology: the power amplifier module is cooled in the tunnel state, which greatly improves the heat dissipation efficiency and stability.
