Supplier: Class T amp, class D amplifier board, digital amplifier module, sound exciter, bluetooth module
Main feature: 1. Class d digital technology with high efficiency, save energy and run in low temperature. 2. Balanced input xlr stereo (two ways) has two modes for selection, one is stereo and the other is bridging. 3. Functions of independent limiting, overload, overheating will protect the circuit. 4. Using ntc soft start up and pfc automatic voltage regulator circuit, so that it can work in ac-90v-240v. 5. Every channel has protection function for over voltage, overheating and overload. 6. Automatic limiting function can prevent the speaker from being damaged. 7. The class d amplifier performs surprisingly with the driving bass. 8. Equipped with high quality imported components.
