The ASCSONIC SD5004S is a compact 4-channel Class D power amplifier designed for professional audio systems, fixed installations, mobile sound reinforcement, commercial AV, and PA applications. With a space-saving 1U design and high power density, it provides an efficient solution when rack space, system weight, and reliable output performance are important.
The amplifier delivers 4 × 500W at 8 ohms and 4 × 900W at 4 ohms, providing flexible power for professional loudspeakers, stage monitors, distributed sound systems, and medium-power PA setups. In bridge mode, the SD5004S can provide 2 × 1600W at 8 ohms for applications requiring higher output from individual channels.
Built around Class D amplification technology, the SD5004S combines efficient power conversion with a lightweight chassis. Its forced-air cooling system helps maintain stable operation during continuous use, while multiple protection circuits help safeguard the amplifier and connected loudspeakers against short circuit, over-temperature, over-current, over-voltage, under-voltage, and DC-related faults.
