Key Features
-
QuadBridge Technology: Configure each 4-channel block in Mono, V-Bridge, I-Share, or Quad modes to allocate power as needed. This technology supports both low impedance and 70/100V loudspeaker loads.
-
ControlSpace Designer Software: Fully configure the amplifier via USB or Ethernet connections—access advanced features such as parametric EQ, load sweep, and auto standby.
-
Auto-Standby/Auto-Wake Function: This energy-saving feature automatically transitions the system into standby mode when audio levels are low and reactivates it when audio resumes, reducing power consumption.
-
Dual Voltage and Current Feedback Loop: This proprietary design combines Class-D efficiency with precise control over current and voltage, ensuring optimal frequency response and minimal distortion.
-
PeakBank Power Supply: A regenerative 4-quadrant power supply provides higher power density and efficient low-frequency response.
-
Fast-Tracking Power Factor Correction (PFC): Manages AC mains current efficiently, allowing for maximum output without power fluctuation.
