retractable rack Lights, rear panel Lamp
and dimmer Control:
The PL-8 Pro II utilizes a dimmer control for
the two retractable front panel light tubes.
The dimmer knob controls the brightness
of both light fixtures. Turn it clockwise to
increase brightness; turn it counterclockwise
to decrease brightness. When the lights are
not in use, we recommend turning the dimmer
fully counterclockwise to maximize the life
of the LED’s, however, this is not absolutely
necessary. Whether the light tubes are
retracted or flush with the front panel, there will
be no appreciable heat regardless of dimmer
setting due to the efficiency of our full light
spectrum LED’s. The Series II’s front panel
LED lamps must be replaced by qualified
Furman service personnel.
Both units feature a rear rack BNC socket
which will accept any 12 VAC (0.5A)
gooseneck lamp assembly, (such as the
Furman GN-LED or GN-I). Simply slide the
BNC plug over the socket and rotate clockwise
until the connector snaps into the locked
position. The rear rack lamp can be powered
on or off with the rear light power switch
located on the far left of the front panel.
on/off Circuit Breaker:
This 20 amp capacity magnetic circuit breaker
switch is specifically designed to stand up to
the enormous high inrush current demands
of many Power Amplifiers. Additionally, the
switch is shielded from accidental power
disconnection with a hinged cover.
Extreme Voltage Shutdown (EVS) Indicator:
This LED is normally off. It monitors a hazard
common in the entertainment industry: wiring
faults – for example, accidental connection
to 220VAC where 120VAC is expected, or an
open neutral from a 208 or 240VAC feed. The
Series II 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 135V, it will
shut off power to the outlet and the Extreme
Voltage LED will light.
notE: The P8-Pro II and PL-8 Pro II do not
compensate for extremely high or low line
voltage. If you frequently move your rack
to different locations, derive power from
generators, use long extension cords, travel
internationally, or are in an area prone to
brownouts, you should use of one of Furman’s
AC Line Voltage regulators.
protection oK Indicator:
Although the Furman SMP+ circuit assures
virtually protection from transient voltage
spikes and surges, nature has a way of
occasionally creating electrical forces that are
beyond the capabilities of any TVSS device to
absorb without some degree of damage. In
the rare instance that this occurs, the green
“Protection OK” LED indicator located on your
front panel will dim. 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 first checking the source
of the problem, and perhaps changing the AC
source.
