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 Elite-15 DM may 

be left with its power engaged permanently at a 

cost of pennies per month. 

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 Series 

Multi-Stage Protection Plus (SMP+) 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 

voltage exceeds 137V, it will shut off power to 

the outlet and the Extreme Voltage LED will 

light.   

Protection OK Indicator:

Although the Furman SMP+ circuit assures 

virtually maintenance free protection from 

transient voltage spikes and surges, nature 

has a way of occasionally creating electrical 

forces that are beyond the capabilities of any 

Transient Voltage Surge Suppression device 

to absorb without some degree of damage.  In 

the rare instance that this occurs, the blue 

LED located in the center of the front panel 

will dim, even though AC power is present at 

the unit’s outputs.  If this happens, some level 

of protection from voltage surges will remain, 

but the Furman’s clamping voltage rating will 

be compromised. The unit must be returned 

to Furman Sound, or an authorized Furman 

Service center for repair. 

NOTE: If the mains power is above the high 

cutoff voltage and has caused the unit to 

remove power from its outlets, it cannot restore 

power without the operator manually turning 

the unit off, then on again. Avoid turning the 

unit back on, without fi rst checking the source 

of the problem, and perhaps changing the AC 

source.

Telco – Satellite – Cable Transient Voltage 

Surge Suppressors 

The Elite-15 DM features transient voltage 

surge suppression for both standard telephone 

lines, as well as cable or satellite lines utilizing 

standard coaxial connectors.  As these surge 

suppressors are in-line, they will require an 

additional cable to connect from their output to 

the control device requiring protection.

All in-line surge suppressors feature 

our exclusive ground contamination free 

technology.  This aids in eliminating audio 

buzzing, and the video hum-bars that can 

result from typical in-line suppressors.  Further, 

our cable and satellite suppressors are TIVO 

friendly as well as HD-Digital Television 

ready.  Both DC carrier signals as well as high 

bandwidth signals can pass through our circuit.  

In fact the bandwidth is less than 0.1dB loss at 

1GHz!
