Suitable for single-phase, two-phase, or three-phase operation in the range of 85 V AC to 460 V AC,
providing maximum flexibility and functionality in any distribution system design. Power load balancing
with PFC (Power Factor Correction) technology can enhance the efficiency of power allocation
operations. The legendary Green Audio Power technology can improve efficiency, minimizing carbon
emissions and electricity operating costs.
Innovative power design
The built-in 4x4 i/o matrix provides highly flexible routing options, allowing users to mix and route
analog and digital inputs/outputs. Simple, plug and play DSP RS485 networks allow any node to easily
route to dBa PCAudio software. Equipped with four input channels for physical simulation, it provides
maximum flexibility in customizing input backup strategies, allowing automatic switching of input
sources in the event of signal failures, thereby improving system reliability. The user interface has been
fully integrated into the dBa PCAudio software.
With High dynamic range and powerful top DSP output FIR equalizer, and high bottom filter. A complete
set of limiters: peak limiting, RM voltage limiting, RMS current limiting, and Green AUDIO Power.
Comprehensive circuit hardware protection: above/below the specified AC voltage; Dangerous signal
(clipping distortion, Super high frequency, long-term RMS); DC output; Overtemperature; Short circuit;
Mute sound when turning on/off.
