Description
The AudioCenter D4.6K-D adds Dante network audio to the four-channel D4.6K high-output Class-D DSP platform. It is designed for professional systems that require substantial amplifier power, centralized network control, multiple digital and analog source paths, and integrated loudspeaker processing.
The amplifier provides 1,100 watts per channel into 8 ohms, 1,750 watts per channel into 4 ohms, or 3,500 watts per bridged pair into 8 ohms. Four analog, four AES, and four Dante inputs feed a 48 kHz/24-bit DSP with IIR crossovers, four channels of 2,048-tap FIR processing, matrix routing, equalization, delay, compression, and limiting.
BrainCore NET allows centralized monitoring and device management through dual RJ45 ports. The 2U chassis uses front-to-back forced-air cooling and a comprehensive protection system for touring, rental, fixed installation, and high-output multi-amplifier systems.
