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
