After many experiments with different modules, this is the one we believe gets the most out of Class D.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eClass D has improved enormously and in areas like bass control it has led for some time. Pascal modules are used by many high-end brands, for good reason. Paired with a great preamplifier, the Essence gives the most demanding speakers the control they need.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eClass D, Done Properly\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe Essence uses Pascal’s UMAC Class D design with a full-bandwidth PWM modulator and an advanced feedback loop taken directly at the speaker terminals. That keeps distortion ultra-low (below 0.05% THD+N) and delivers a damping factor above 1000 at 1 kHz, for firm, exact woofer control.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eOur Own Input Buffer, XLR Input\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eWe designed our own input buffer with a balanced XLR input. If your preamplifier, tube or otherwise, has RCA outputs, we also provide an XLR to RCA adaptor, so you can connect the Essence to almost any system.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003ePower Reserve and Efficiency\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe Pascal UREC switch mode power supply is universal mains, with Power Factor Correction (PFC) and an integral standby converter. It is heavily oversized for this amplifier and delivers up to 1150 W maximum. In standby it draws just 0.35 W.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eAt 89% efficiency, very little energy is wasted as heat. That is why the Essence needs no fan, no ventilation tricks and no noisy cooling. The result is a compact, silent, solid aluminum chassis.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eA Black Background\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eWith a signal-to-noise ratio above 120 dB, the noise floor disappears.
