Delivering up to 400W in bridged mono mode with vanishingly low distortion, a fully-balanced XLR input stage, and precision PGA2311 digital volume control, the PA200 drives bookshelf and floorstanding speakers alike with effortless dynamics, deep bass control, and a noise floor so low you will forget the amplifier is even there.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eGallium Nitride: The Next Generation of Power\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eGaN transistors represent a fundamental leap beyond traditional silicon. They switch faster, run cooler, and waste far less energy as heat. In the PA200, this translates to higher efficiency, lower distortion at all output levels, and a compact chassis that does not need massive heatsinks to stay composed under load. The result is a power amplifier that delivers 400W mono into 4-ohm loads while running quiet, clean, and cool.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eStereo and Bridged Mono Flexibility\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIn stereo mode, the PA200 delivers ample power for most speaker setups. For those seeking maximum headroom, bridged mono mode unlocks up to 400W into 4 ohms using a single PA200, or deploy a pair in dual-mono configuration for truly authoritative bi-amped control. Switching between modes is straightforward, making the PA200 adaptable to evolving system requirements.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFully-Balanced XLR Inputs\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTrue balanced XLR inputs reject common-mode noise and ground-loop hum before they enter the signal path, preserving the full dynamic range and stereo separation of your source. Combined with high-quality RCA inputs for single-ended sources, the PA200 integrates cleanly into both professional and consumer audio chains.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003ePGA2311 Precision Digital Volume Control\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTexas Instruments' PGA2311 provides 0.5 dB step precision with near-perfect channel tracking from zero to maximum gain.
