The SWA‑200 subwoofer amplifier delivers clean, solid power required to drive small‑to‑medium sized subwoofer speakers. Its compact design is compatible with many other popular electronic devices and different styles of multimedia gear. The SWA‑200 is engineered to provide high fidelity bass amplification and is tailored for home audio and home theater audio systems. Its volume, crossover frequency, and phase adjustment guarantee perfect integration with any audio system in any listening environment. Short circuit and thermal protection circuits are built‑in. While deep, hard hitting bass is fun and a little annoying to the neighbors, a good subwoofer system also improves your main speaker's fidelity. By driving a separate subwoofer system, your left and right speakers are free to articulate dialog and subtle audio accents while the explosions are hitting you in the chest. This subwoofer amp is an ideal match to our passive in‑wall subwoofer (PID 4928). The SWA‑200 is stable down to 4 ohms, so it will easily drive one or two subs. Use the front panel crossover and phase controls to dial in the sound just the way you want it. Features: 200 watts of deep, hard‑hitting power at 4 ohms impedance Front panel volume, crossover, and phase controls to tailor your sound to your need Compact design fits anywhere you need it Cool running Class D amps are quiet and can run all night Support Files: User's Manual (Jul 18, 2018) Monoprice™ and all Monoprice logos are trademarks of Monoprice Inc.
