Foshan Huiming Electronic Technology Co., Ltd.
D7150 Multi-channel Amplifier
Features:
1, It supports most for 5 channels 150W and SUB 400W (D5150) or 5 channels 250W and SUB700W (D5250), also supports bridge between the 2 channels and all kinds of power collocation, accepting personalized customization;
2, It’s specially designed for theater, meeting room and Karaoke, so the sound is clean and clear;
3, It’s the first plug-in card amplifier with patent technology in this industry, while the maintenance is easy and you can change the main board in a short time;
4, There is patent technology for intelligent circuit-controlled fan, when the speaker is no sound, the fan doesn’t work, making you feel quiet;
5, Optional hard limiter and soft limiter are for you, and when it’s overload, the amplifier output will be no clipping;
6, There is overall protection: Soft Start of Switch On, Over Load, Superheated, Short Circuit, Direct Current Output, Peak Limiter, Intelligent Peak Clipping, Zero Current Switching for output;
7, We insist on the same commercial process, because we have all the equipments: Automatic Surface Mounting Machine, Automatic Plug-in Machine, Wave-Soldering, Programmable Screw Machine.
