Overview
The Sound Barrier DA8.4 is a high-power four-channel Class-D amplifier engineered for professional systems that require substantial output and flexible multi-channel configuration. It delivers 4 × 2000W at 4Ω and 4 × 1350W at 8Ω, making it a versatile choice for subwoofers, full-range loudspeakers, stage monitors, and multi-speaker systems in touring productions, nightclubs, live venues, houses of worship, and fixed installations.
Its compact 1U architecture supports stereo, mono, and bridge operation, with selectable 38dB, 35dB, 32dB, and 29dB gain settings. The amplifier supports minimum loads of 2Ω per channel in stereo or mono operation and 4Ω in bridge mode, with burst output up to 4 × 2800W at 2Ω or 2 × 5500W bridged at 4Ω.
A universal switch-mode power supply with active Power Factor Correction provides efficient, stable performance across a worldwide AC input range. Front-to-rear temperature-controlled cooling and protection against undervoltage, DC output, over-temperature, overload, and short circuit help deliver dependable performance in demanding professional applications.
