Feature:
1>. D3 powered speaker module consists of class D amplifier board; switching power supply and DSP module.
2>. It is 1800W+900W+900W at 4 ohms 3 channels module
3>. This module is mounted an agile DSP module for versatile PA Systems Performance, you could manage this PA system via PC which connected with a USB or RS-485 cable.
4>. Compact installation dimension with powerful output
5>. D3 is perfect for three way line array speaker or one touring sound reinforcement system consists of one subwoofer and two bi-amped top speaker.
Advantage:
1> Big power and multi-channel module: 1500W+ 500W+500W at 8 ohms; 1800W+900W+900W at 4 ohms; three way DSP active module;
2> Small mouting size: It is easy to install into the cabint box.
3> Efficiency: One active module can power one subwoofer + two top line array.
Benefit :
1> Simple the system: One unit D3 active module is with DSP function. It means we do not equip digital processor to the system.
2> Save cost: The 2U or 1U power amplifier is with double price of D3.
