Overview

Overview: The DA8.4 is a high power 4-channel Class-D amplifier engineered for professional audio systems requiring strong output and flexible multi-channel configuration. Delivering up to 3400W per channel at 4Ω, it is designed to drive full-range loudspeakers and subwoofer systems in demanding applications such as DJ setups, live sound reinforcement, nightclubs, and small to mid-size venues. Its 4-channel architecture allows efficient system design by powering multiple speakers or subwoofer drivers from a single amplifier, making it ideal for reducing rack space and simplifying wiring. The advanced Class-D design ensures high efficiency with reduced heat generation and power consumption, while the switching power supply with active Power Factor Correction (PFC) provides stable performance across a wide voltage range. With support for stereo, bridge, and mono operation modes, along with selectable gain settings, the DA8.4 integrates easily into a variety of professional audio systems and DSP configurations. Built for reliability, it features a front-to-rear cooling system with temperature-controlled fans and comprehensive protection circuits, including over-temperature, short circuit, overload, DC, and undervoltage protection. Whether used for subwoofer amplification or full-range speaker systems, the DA8.4 delivers the power, efficiency, and flexibility required for professional audio applications.1
