ELITE 20 PF OWNER’S MANUAL
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 rst checking the source of the problem,
and perhaps changing the AC source.
Telco – Satellite – Cable Transient Voltage
Surge Suppressors
The Elite-20 PF 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!
To connect your cabling to these in-line protectors,
simply follow the in and out indications marked
next to the Telco, Cable and Satellite connectors.
Note: It is not possible to make an a telco
(telephone –line), satellite or cable protector
“maintenance-free” as we have accomplished with
the 120 VAC line. This would necessitate limited
signal bandwidth that would not allow the signal
to pass. Under extreme conditions, it is possible
that the surge suppression in one of these
devices could sacrice itself after a catastrophic
event. If the telephone, cable or satellite signal
will no longer pass through our protector, please
contact your local service representative, installer
or Furman for servicing. Since the telco circuit
is modular, replacement may be accomplished
in seconds with a new telco TVSS module. To
test this, simply disconnect the incoming and out
going phone line from the Elite-20 PF. Connect
the incoming connector to the component that
formerly received the out going connector, thus
by-passing the in-line protection. If the signal is
present (but not when used with the Elite-20 PF)
then the protection circuit is damaged (assuming
it worked properly before a storm or catastrophic
event). With Cable or Satellite protection, it is
HIGHLY unlikely that the protection device will
ever fail unless a severe lightening strike literally
deforms the connector. If this occurs, return to
Furman Sound for Servicing.
