Retractable Rack Lights, Rear Panel Lamp
and Dimmer Control:
The PL-PRO E II, PL-PRO PE II, PL-PRO
DE II and PL-PRO PDE II include a dimmer
control for the two retractable front panel light
tubes. Turn it clockwise to increase brightness
of both light fixtures, or counterclockwise to
decrease brightness. Turning the dimmer
fully counterclockwise when the lights are
not in use, will maximize the life of the LEDs:
however, this is not absolutely necessary.
Whether the light tubes are extended or flush
with the front panel, our high-efficiency, full-
spectrum LEDs generate no appreciable heat.
All Series II units feature a rear 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.
Series II front panel LED lamps must be
replaced by qualified Furman service
personnel.
Multi-Segment LED voltmeter:
(PL-PRO E II and PL-PRO PE II)
This three-color, 20-LED bar graph is an
accurate, self checking AC voltmeter that
continually measures normal voltages. The
meter reads from 180 to 256 volts in 4 volt
increments. Voltages within the normal range
are indicated in green, with moderate and
extremely high or low voltages in yellow and
red respectively. The voltmeter warns of
abnormal conditions by flashing the LEDs in
one of three special patterns.
1. If only the single leftmost LED (beneath
the 180V mark) flashes, the input voltage is
marginally low.
