Connection

AC Cable Routing

Once the SPR-20i is placed, its AC cord’s female end must be plugged into the male IEC connector located on the lower left hand side of the rear panel (when facing the rear panel). Next the male Edison plug must be connected to an appropriate socket (see current rating recommendation above).

Connecting Components to the Digital - Video Component AC Outlet Banks

The SPR-20i’s four “Digital - Video Component AC Outlets” should be employed for critical video components such as DVD players, projectors, Plasma, or LCD video screens. When employing the SPR-20i for a 2-channel audio system, a pre-amplifier and or CD player would be ideally suited for these outlets.

Connecting Components to the Linear Filtering Power Banks

The SPR-20i’s eight rear panel, and one front panel, Linear Filtering Power Outlets should be employed for any component not connected to the four “Video Components” outlets. These outlets still posses incredible AC noise filtering to maximize system performance.

Soft Start - Continuous Use and Break-In Time

When power is first applied to the SPR-20i, (the front panel breaker- power toggle must be switched to the “on” position) the Soft Start feature is activated. There is an audible “clack” when the SPR-20i is first turned on or off. This sound is produced by the Soft Start circuit’s 30 Amp relay engaging or disengaging. There is virtually nothing in the SPR-20i’s construction, design, or componentry to wear over the life time of the product, and there is no power draw from your electric service meter aside from the LED power indicator, and relay circuits. For this reason the SPR-20i may be left with its power engaged permanently at a cost of pennies per month. This is an added benefit, as many audio/videophiles find performance improves significantly when leaving low-powered components permanently charged (turned on). In fact, this is true of the SPR-20i. Though it will function flawlessly right from its shipping carton, the performance of its circuit parts will improve after approximately two weeks of continuous use or “break-in.”

AC Transient Voltage Surge Suppression and Extreme Voltage Shutdown

Extreme Voltage Shutdown Indicator

This LED is normally off. It monitors AC wiring faults – for example, accidental connection to an open neutral from a 208 or 240VAC feed (this is a common occurrence if the 15 Amp outlet source is not a dedicated line, but instead has been wired with a daisy-chained neutral from a homes breaker box). The Extreme Voltage Shutdown (EVS) circuit senses voltages that are so high that operation would be impossible and shuts the power down before damage can occur. Upon initially applying power to these units, the Extreme Voltage indicator LED will light if the input voltage is above the extreme voltage cutoff, and power will not be applied to the unit’s outlets. If the unit has been operating with an acceptable input voltage and subsequently that

SPR-20i specifications

Furman Sound has long been at the forefront of power management technology, and their SPR-20i unit is a prime example of their innovation and engineering prowess. The SPR-20i is a highly advanced power conditioner designed for professional audio applications. It combines superior power protection, voltage regulation, and filtration to ensure that audio equipment operates at peak performance.

One of the standout features of the SPR-20i is its Linear Filtering Technology (LiFT), which significantly reduces electromagnetic and radio frequency interference. This technology ensures that power reaching your equipment is clean and stable, essential for high-fidelity audio reproduction. By minimizing noise, it enhances the performance of connected devices, resulting in a cleaner sound with greater detail and clarity.

Another key characteristic of the SPR-20i is its SmartSequencing technology. This feature offers intelligent power sequencing for up to eight connected devices. By controlling the startup and shutdown sequence, it prevents power surges that can damage sensitive audio equipment. This is particularly beneficial in live sound environments, where equipment is often powered up and down frequently.

The unit's robust build quality is also worth noting. Encased in a durable rack-mountable chassis, the SPR-20i is designed to withstand the rigors of touring and extensive use in studio environments. It includes high-quality receptacles with superior connections to reduce resistance and ensure long-lasting performance.

For ease of use, the SPR-20i features a user-friendly digital display that provides real-time information about voltage levels and power consumption. This allows sound engineers and technicians to monitor the power conditions of their setup at a glance, making any necessary adjustments swiftly.

Additionally, safety is a top priority with the SPR-20i. It offers comprehensive surge protection and over-voltage protection, safeguarding your valuable equipment from power spikes and fluctuations. Its built-in circuit breaker further enhances safety, allowing for quick resets if needed.

Overall, the Furman Sound SPR-20i is an intelligent power management solution that combines advanced technologies with practical features. With its focus on clean power, equipment protection, and ease of use, it stands out as an essential tool for audio professionals seeking to optimize their audio systems.
