Sound Barrier DA9.2 — 2-Channel Class D Power Amplifier
DA9.2 Overview
The Sound Barrier DA9.2 is a high-output, 2-channel Class-D amplifier built for professional audio environments that demand sustained power and reliable performance under heavy load. Delivering 5000W per channel at 4Ω, it is purpose-built to drive subwoofer stacks and high-output loudspeakers in nightclubs, live venues, touring rigs, and rental production. The advanced Class-D design provides high efficiency with reduced heat generation and power consumption, while the switching power supply with active Power Factor Correction (PFC) ensures stable operation across a wide voltage range. The DA9.2 is an ideal choice for audio engineers, system integrators, and touring companies requiring consistent, high-power amplification in demanding professional applications.
With support for stereo, bridge, and mono operation modes along with selectable gain settings, the DA9.2 integrates directly into DSP-controlled systems and complex signal chains without compromise.
