Built around PLFC+ Discrete amplifier technology and featuring a 120 dB signal-to-noise ratio, dual NJU72315 volume control, and comprehensive connectivity including 6.35mm single-ended, 4.4mm balanced, and XLR outputs, the H200 delivers uncompromising power, vanishingly low distortion, and absolute channel matching — whether driving high-impedance dynamics or current-hungry planar magnetics.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003ePLFC+ Discrete Fully-Balanced Amplifier Technology\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe H200 employs PLFC+ discrete-component fully-balanced amplifier circuit to achieve extraordinarily low distortion and noise levels. The AAA-888 circuit topology uses a carefully selected discrete components maintaining a true balanced signal path that cancels distortion components before they reach the output stage, resulting in a noise floor that is effectively inaudible and a signal path so transparent that what you hear is the recording — not the amplifier.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFully-Balanced Architecture from Input to Output\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTrue fully-balanced signal handling runs from the XLR inputs through the volume control stage to the balanced headphone and preamp outputs. This end-to-end differential design rejects common-mode noise, doubles the voltage swing capability, and provides superior channel separation compared to single-ended designs. The result is a wider soundstage, tighter bass control, and greater dynamic expression with balanced headphones.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003ePGA4311 Precision Volume Control\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eVolume is managed by the Texas Instruments PGA4311, a 4-channel digitally-controlled analog resistor-ladder volume chip. Unlike conventional potentiometers that suffer from channel imbalance at low levels and degrade over time, the PGA4311 offers 0.5 dB step precision with near-perfect channel tracking across the entire attenuation range — from whisper-quiet to concert-level.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eTriple Headphone Outputs for Maximum Flexibility\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe H200 accommodates every headphone connection standard: 6.35mm single-ended, 4.4mm Pentaconn balanced, and 4-pin XLR balanced. All three outputs are driven by dedicated output buffers with independent protection circuits, allowing you to connect multiple headphones simultaneously without compromising performance.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDual NJU72315 Preamp Stage\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhen used as a preamplifier, the H200's dual NJU72315 balanced output stage drives power amplifiers and active speakers with the same transparency it delivers to headphones. Selectable fixed and variable output modes make it equally suited as a dedicated headphone amp or as the control center of a compact desktop speaker system.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eBright OLED Display with Real-Time Feedback\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA high-contrast OLED screen provides clear visibility of input selection, volume level, gain setting, and output mode.
