Overview

The Sound Barrier DA9.2 is a high-power two-channel Class-D amplifier engineered for professional loudspeaker systems that need substantial output in a compact rack format. It delivers 2 × 5000W at 4Ω and 2 × 3000W at 8Ω, making it well-suited to high-output subwoofers, full-range loudspeakers, stage monitors, and demanding sound-reinforcement 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 41dB, 38dB, 35dB, and 32dB 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 2 × 6500W at 2Ω or 1 × 13000W 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.
