Introduction: Thank you for your purchase of a Knöll PRM150 or PRM200 Advanced
Power Conditioner and congratulations on your choice. This specially made
conditioner is designed specifically to reduce noise and hum pickup by sensitive
equipment when ultra-low-noise is a must as well as surge suppression to protect
your valuable electronics.
FEATURES:
• PRM150 rated for 15 amps, PRM200 rated for 20 amps (with special power
plug)
•
•
•
Push button or 4-24 VDC trigger power on/off
2210 Joules surge protection
Eight rear panel, heavy duty AC outlets includes two unswitched, and six
sequence delayed switched outlets with Digital Isolated Outlets
Main power cord is a 10 foot, ultra heavy duty 14 Ga. (PRT200 8 foot 12 ga.)
for easy access to a wall socket
Rear panel cable TV connectors for surge protection and noise filtering with
satellite or cable TV
One rack space
•
•
•
ADVANCED SURGE SUPPRESSION- Edge-of-the-art two level suppression with
an astounding 2210 Joules of lightning protection (most current competitive units
only have 360) in the AC power line! Add the cable TV, satellite dish and telephone
line protection and you have 3590 joules of total protection!
In the event the unit does not power up after a surge, a small internal board
replacement may be all it takes to keep on protecting your sound and picture quality
as well as your investments.

Installation:
The PRM200 power source connection must be adequate for use at 20 amps. We recommend
a properly grounded 30-amp circuit, wired with 10-gauge wiring, if continuous operation near
20 amps is anticipated. A dedicated (nothing else connected) 20-amp circuit is the minimum
acceptable to comply with NEC requirements. Consult a qualified electrician if in doubt.
Please note the PRM200 cord plug requires a different style outlet than a conventional style
15-amp outlet.

The PRM150 requires a dedicated properly grounded 15-amp circuit to operate at capacity.
We suggest that a dedicated 15-amp breaker be installed at the breaker box for use with
the PRM150.
It is best if the PRM150 or PRM200 is located with other equipment so that extension
cords are not required. Heat is not a consideration when placing the power conditioner.
Plug all the AC power cords from all components directly into the back of the power
conditioner. This offers full line conditioning and filtering for your entire system.
Keep in mind that Knoll power conditioners can only do so much in the cases of lightning
strikes and large surges. If your area is prone to lightning strikes and large surges we
strongly suggest you have a whole house lightning arrestor installed. Ask you power
provider for more information.
The un-switched outlets are for components that require full time power such as VCR’s or
TV’s. If you wish to turn on your system via an existing component with remote control
access (such as a receiver with a switched ac outlet on the back), plug your receiver into the
un-switched outlet on the power conditioner (and read the section below on rear panel
trigger).

Delayed Turn On’s.
When the power conditioner is turned on, the two outlets labelled “Delay Min” turn on
immediately (along with the unswitched outlets already turned on).
About two seconds later the next two outlets labelled “Delay Med”
turn on.
About two seconds later (four seconds from when the power conditioner was first turned
on) the last two outlets labelled “Delay Max” turn on.
Typically ancillary equipment such as equalizers, processors, DVDs etc. are connected to the
outlets labelled Delay Min and Delay Med.
Typically larger power amplifiers are connected to the outlets labelled “Delay Max” so that
other equipment has time to stabilize before the amplifier gets power, seriously reducing
loudspeaker clicks and pops. If multiple amplifiers are too powerful to connect to a single
Knoll power conditioner, we suggest using a 12V DC wall wart power supply connected to the
Delay Max outlet on the power conditioner and connect the wall wart to the amplifier
trigger input(s). The amps are plugged into the wall and not to the power conditioner.
If there is two larger amplifiers to be connected to this power conditioner, we suggest that
one be connected to the outlets labelled Delay Med and the other to the outlets labelled
Delay Max.
If a longer eight-second turn on sequence instead of the standard four second start up
sequence is required, your authorized Knoll dealer can remove an internal shunt to
accomplish this.
Power Down
When the power down command is received by the Knoll Power Conditioner a reverse
sequence to the power up is initiated. Immediately when the power down command is
received, the outlets labelled “Delay Max” are shut off. Two seconds later, the outlets
labelled “Delay Med” are shut off. Two seconds later, the outlets labelled “Delay Min” are
shut off. The last two outlets labelled “Unswitched” are never shut off.
Rear Panel Trigger
The Knoll Power conditioner is equipped with a remote trigger activation to turn the power
conditioner off and on (just like the front switch). When a 3-24 VDC or VAC constant signal
(trigger) is present, the power conditioner will power up in sequence and stay on as long as
the signal is present. When the trigger signal is lost, the power conditioner begins its power
down sequence and stays off until either a trigger signal is reacquired or the front panel
power button is pressed. When connecting to the trigger, polarity is unimportant.

Fuses
There is a single slow blow 15-amp fuse in the PRM150 and there is a single 20 amp slow
blow fuse in the PRM200. As per safety regulations, only authorized and experienced
service people, including Knoll factory personnel are authorized to change these fuses. DO
NOT CHANGE these fuses for safety reasons.
Cable TV and Satellite Dish
For best protection, connect the cable TV when it first enters the home to the Knoll Power
Conditioner F connector labelled Cable TV IN. Next connect up the rest of the home’s TV’s
to the F connector labelled Cable TV OUT. If you have a lousy cable TV picture after this,
check carefully that these were connected correctly.
Likewise connect the satellite dish when it first enters the home to the Knoll Power
Conditioner F connector labelled Sat Dish IN. Next connect the satellite dish receiver to F
connector labelled Sat Dish OUT.
Telephone Connection
Connect a single telephone line pair to the Knoll Power Conditioner rear RJ connector.
Connect the rest of the home’s telephone lines to the other RJ connector. Please note that
even though there is room for three wire pairs only the centre pair is connected and
protected.
