Furman PLPLUSD, PMPRO, PM8, PLPROD User Manual
Metered Six Series
Owner’s Manual
INTRODUCTION
Thank you for your purchase of a Furman Metered Six
Power Conditioner, and congratulations on your
choice. The Metered Six line of Power Conditioners
offer many of the same features that have made
Furman Power products preeminent within the music,
broadcast, and contractor industries for decades.
Now, many of our standard features such as triple
stage surge suppression, retractable rack lights,
over-under voltage shutdown, and multi stage
RFI/EMI filtering, are available with laboratory quality
Digital Voltage and True RMS Current meters.
Your Metered Six unit provides comprehensive
protection from power line-related transient voltages
and noise, while the 20 amp capable PRO units
provide additional protection from wiring faults
common to remote power, theaters, convention
centers, and AC generators. The Metered Six’s fastacting suppression circuit responds in less than a
nanosecond, clamping transient voltages to safe
levels. The RFI/EMI filter works to prevent the noises
generated by fluorescent lights, lighting dimmers,
radio transmitters, and electrical appliances from
contaminating the AC line and from there, leaking
into sensitive audio, video, or computer circuits.

SAFETY
INFORMATION
To obtain best results from your Furman Metered Six
Power Conditioner, please be sure to read this manual
carefully before using.
WARNING
5. Route the power cord and other cables so that
they are not likely to be walked on, tripped over, or
stressed. Pay particular attention to the condition
of the cords and cables at the plugs, and the point
where they exit your Metered Six unit. To prevent
risk of fire or injury, damaged cords and cables
should be replaced immediately.
6. Clean your Metered Six unit with a damp cloth
only. Do not use solvents or abrasiv e cleaners.
Never pour liquid on or into the unit.
To reduce the risk of electrical shock, do not expose
this equipment to rain or moisture. Dangerous high
voltages are present inside the enclosure. Do not
remove the covers. Other than the light bulbs, there
are no user serviceable parts inside. Refer servicing to
qualified personnel only.
The lightning flash with an arrowhead symbol, (within
an equilateral triangle) is intended to alert the user to
the presence of un-insulated dangerous voltage within
the product’s enclosure that may be of sufficient
magnitude to constitute a risk of electric shock.
IMPORTANT
SAFETY
INSTRUCTIONS
(Please read prior to installation)
1. Please read and observe all safety and operating
instructions before installing your Metered Six unit.
Retain these instructions for future reference.
2. Your Metered Six unit should not be used near
water – for example, near a bathtub, washbowl,
kitchen sink, laundry tub, in a wet basement, near
a swimming pool, etc.
7. Your Metered Six unit should be serviced by
qualified service personnel when:
• The power supply cord or the plug has been frayed,
kinked, or cut.
• Objects have fallen or liquid has spilled into the unit.
• The unit has been exposed to rain or other moisture.
• The unit does not appear to operate normally or
exhibits a marked change in performance.
• The unit has been dropped, or the enclosure
damaged.
8. Your Metered Six unit requires that a safety ground
be present for proper operation. Any attempt to
operate the unit without a safety ground is
considered improper operation and could
invalidate the warranty.
9. Light bulbs are the only user-serviceable parts in
the PL-PLUSD, PL-PLUSDM, PL-PROD, and PLPRODM. Instructions for replacing them are on
page/s 4, 5, 6, and 7. The light tubes and end caps
become quite warm to the touch in normal
operation. To avoid burning your fingers, allow the
cap to cool completely before unscrewing it. If you
find that the heat from the tubes is excessive,
reduce the dimmer knob setting.
3. Do not place your Metered Six unit near heat
sources such as radiators, heat registers, stov es,
or other appliances that produce heat.
4. The PL-PROD, PL-PRODM, and PM-PRO should
only be connected to a 120 VAC, 60Hz, 20 amp
grounded electrical outlet. Outlets wired for 20
amps, may be identified by the T-shaped socket
opening that accept the perpendicular blades of
the PRO unit’s power plug. If you don’t have a 20amp outlet, have one installed by a qualified
electrician. Do not defeat the ground or change
polarization of the power plug.
10. Do not attempt to service your Metered Six unit beyond
what is described in this manual. All other servicing
should be referred to qualified service personnel.

FEATURES
The PL-PLUSD features an advanced digital voltage
meter, while the PL-PLUSDM and PM-8DM provide a
OPERATION
Retractable Rack Lights and Dimmer Control: The
PL-PLUSD and PL-PLUSDM utilize 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.
Light Tubes and Bulb Replacement: The PL-PLUSD
and PL-PLUSDM feature the familiar slide-out rack
lights pioneered by Furman. These units’ lamps come
supplied with five-watt night light bulbs. Replacements
are available at most hardw are stores, and may be
purchased from Furman Sound service as well.
BULB REPLACEMENT
laboratory grade True RMS digital voltage and current
meter. Both meters are located at the center-front panel
of their respective units.
A 15 amp circuit breaker is mounted on the front panel,
allowing quick, convenient power restoration. Simply
pushing the square center tab into the front bezel will
re-activate the breaker after an excessive current load
has tripped it.
The rear panel contains eight switched AC outlets
to power your equipment, (4 for analog equipment
and 4 with additional filtering for digital – computer
components, see below). These AC outlets are spaced
to accommodate up to four plug-mounted power
supplies (“wall warts”).
Power is delivered to the unit by a heavy duty 14 AWG
AC cord, 10 feet (2.4 m) in length for extra reach and
durability on stages and other high-traffic areas.
Bulbs are easily replaced without removing the unit
from the rack.
Here’s How: First, pull the light tube(s) all the way out.
Unscrew the cap on the end of each tube to get access
to the bulb. (Be careful not to push the tubes in after
you have removed the caps.) To unscrew the bulb,
place your index finger across the hole on the
underside of the tube and in contact with the bulb. Use
the ball of your finger to rotate the bulb out of its socket.
Then remove the bulb from the front of the light tube.
Put a new bulb in the tube, rotate it with your finger
from the hole in the bottom of the tube and replace
the light tube cap(s).
NOTE: The caps and light tubes become quite warm to
the touch in normal operation. To avoid burning your
fingers, allow the cap to cool completely before
unscrewing it. If you find that the heat from the tubes is
excessive, try reducing the dimmer knob setting. As an
alternative, you may substitute four-watt bulbs or even
colored Christmas tree bulbs.
The Tape Trick: In cases where the bulb is still war m,
or too tight to unfasten with your fingers, a piece of duct
or gaffers tape about 2 inches square can aid in the
bulb removal. Simply pinch about a quarter inch of the
center portion of tape together, and place the remaining
portion of the adhesive backing on the exposed portion
