1800W Peak | 450W RMS per Channel @8Ω | 1U Rack Mount | Engineered for KTV Owners, DJs, Churches & Home Enthusiasts
Whether you're running a multi-room KTV venue, hosting a live concert, leading a church sermon, or setting up a premium home theater, this 2-channel 1U digital power amplifier is your reliable solution for professional-grade sound. We've combined industry-leading power output, ultra-stable performance, and a compact rack-mount design to deliver an amplifier that keeps up with your most demanding audio needs, without the bulk of traditional power amps.
At the heart of this amplifier is a high-efficiency digital power circuit, delivering an impressive 1800W total peak power, with a clean, stable 450W RMS per channel at 8Ω. This means you get crystal-clear highs, rich mids, and deep, punchy bass — even at maximum volume, with zero clipping or distortion. The true dual-independent channel design ensures zero signal crosstalk, giving you full control over left and right channels for stereo precision, or switch to bridged mono mode for boosted subwoofer performance.
We know that downtime costs you money and reputation. That's why this amplifier is built with a rugged black metal chassis, paired with an intelligent thermal management system and multi-layer protection circuit: short circuit protection, overheat protection, and DC protection. It runs cool and stable, even during 10+ hours of continuous daily use in KTV venues, all-day conferences, or back-to-back live performances. The standard 1U rack-mount design saves valuable space in your audio cabinet, making it perfect for both fixed installations and mobile rigs.
No complicated wiring, no compatibility headaches. This amplifier comes equipped with industry-standard professional XLR/TRS inputs and heavy-duty speaker binding posts, making it compatible with nearly all mixers, speakers, subwoofers, and audio equipment. Whether you're a seasoned audio engineer setting up a full stage rig, or a KTV owner upgrading your venue's sound system, the intuitive design makes setup fast and straightforward, so you can focus on what matters most: your sound.
