Furman SPR-16Ei Stable Power AC Voltage Regulator
The Foundation of a High-Performance System
The Furman SPR-16Ei is a reference-grade AC voltage regulator representing a revolutionary advancement in stable power delivery for high-performance audio, video, and home theatre systems. For over 40 years, Furman has led the development of AC power solutions for professional audio, video, and broadcast applications, and the SPR-16Ei brings this expertise to bear in a component that addresses one of the most commonly overlooked limiting factors in any serious audio system: the quality and consistency of the AC supply itself. Unstable AC voltage affects audio and video quality in two critical ways: voltage drops reduce sonic impact and dynamic authority, while excessive voltage shortens the lifespan of sensitive components. The SPR-16Ei eliminates both problems, ensuring a constant, regulated power supply that allows every component in the system to perform at its absolute potential.
Stable Power AC Voltage Regulation Technology
The SPR-16Ei’s core technology is Furman’s Stable Power AC Voltage Regulation, which maintains a continuous output of 230VAC within plus or minus 5 volts across an input voltage range of 213VAC to 245VAC. Unlike conventional AC regulators that generate excess heat and mechanical noise in the process of voltage regulation, the SPR-16Ei’s zero-crossing solid-state technology delivers peak current without these limitations, operating silently and efficiently under all load conditions. The practical result is an AC supply of exceptional stability that removes voltage fluctuation as a variable from the system, allowing amplifiers, subwoofers, digital components, and sensitive analogue circuitry to operate exactly as their designers intended at all times.
Linear Filtering Technology for Complete Noise Elimination
Furman’s Linear Filtering Technology provides transverse mode noise attenuation of greater than 40dB from 10kHz to 100kHz and greater than 80dB from 100kHz to 1GHz, eliminating the RF and EMI interference that degrades the clarity, depth, and resolution of both audio and video signals. The SPR-16Ei provides twelve filtered outlets in total: one 16-amp linearly filtered outlet, seven standard linearly filtered outlets, and four linearly filtered outlets with additional ultrasonic filtering specifically optimised for video components. This configuration ensures that every component in the system benefits from appropriate filtering for its specific requirements, with video components receiving the enhanced ultrasonic filtering that produces crisper images and deeper blacks.
Series Multi-Stage Protection and Real-Time Monitoring
The SPR-16Ei’s Series Multi-Stage Protection provides industry-leading transient voltage surge suppression without degrading over time, ensuring maximum protection without sacrificing performance. Unlike sacrificial surge protection designs that lose effectiveness after each surge event, the SPR-16Ei’s non-sacrificial protection with zero ground contamination maintains its full protective capability indefinitely. A shutdown range of greater than 275VAC protects connected components from dangerous overvoltage conditions, while real-time digital voltage and current meters allow precise monitoring of the AC supply at all times. When paired with Furman’s IT-Reference 16Ei, the SPR-16Ei delivers an unparalleled combination of stable power and discrete symmetrical AC filtering for the ultimate in system power optimisation.
