The Clarus approach to power conditioning represents a radical new way of designing an application specific AC
energy system. It is widely accepted that filtering the AC line keeps noise from contaminating the audio signal. It is also
common knowledge that some filter designs will choke input current thus limiting peak performance of power
amplifiers. Through extensive listening sessions, Clarus has determined that some filter designs used for conditioning
analog components while measurably removing noise from the AC supply audibly degrade the component’s musical
output and restrict the sound from blooming.
The Clarus Solution is the implementation of three separate and unique AC filter ensemble designs for its new line of
Power Conditioners; one for Analog components, one for Digital components and one for High Current amplifiers.
The Clarus Duet Power Block is designed with the strength and size to support the demands of a mono block amplifier.
FEATURES AND TECHNOLOGIES
1800 WATT / 15 AMPERE RATING
The Clarus Duet is designed to provide a maximum of 1800 Watts / 120 volts @ 15 Amps.
2 OUTLETS
The Duet’s high performance hospital grade outlets are engineered with advanced materials to ensure electrical
contact reliability over time. Two outlets labeled: HIGH CURRENT incorporate a massive 30A Clarus-Core filter to
deliver full power without restricting dynamics to high current equipment like mono block amplifiers.
C-CORE TECHNOLOGY
Clarus line of power conditioners are made with proprietary Clarus-Core or “C-Core” Technology which is used in all
Analog and High Current filters. C-Core’s high permeability and core loss are hardly affected by mechanical stress due
to near-zero magnetostriction - a property of ferromagnetic materials that causes them to change their shape or
dimensions during the process of magnetization. Furthermore, its low magnetostriction significantly reduces audible
noise emission when the voltage and current applied to the core are in the audible frequency range. No other core
performs as well to keep your AC signal silent and clean.

TMOV
The Duet protects from surges with highly sophisticated Thermal Metal Oxide Varistors (TMOV). If the surge
suppression circuit is compromised the front panel Protection Fault LED will illuminate and the unit will shut down for
safety.
GROUND POST
A dedicated ground post on the rear panel allows for the grounding of other sensitive electronics within the system.
SIDE PANEL MAIN POWER SWITCH
For safety, the Duet incorporates a heavy duty 30amp main power switch on the side of the chassis.
SIDE PANEL CIRCUIT BREAKER
If the Duet experiences an incoming current in excess of 15A, the side panel circuit breaker will trip and disconnect the
mains power. To reset the breaker simply push RESET.
OUTLET POWER STATUS
A blue LED is provided on the top panel of the Clarus Duet to indicate status of the outlets. When the Power LED is
illuminated it means power status of the outlets is ON.
PROTECTION FAULT LED STATUS If the PROTECTION FAULT LED illuminates it means the Surge Suppression
electronics have been compromised and the unit will no longer be passing power to the outlets.
POLARITY & GROUNDED LED STATUS
Polarity and Grounded LEDs will illuminate to indicate that the AC outlet into which the Clarus Duet is connected is
wired correctly. If the GROUNDED LED does not illuminate the power cord and the outlet into which the Clarus Duet is
connected are not properly grounded. If the Polarity LED is not illuminated when the front panel power switch is
activated the White and Black AC wires of the outlet into which the Clarus Duet is connected are reversed.
DO NOT OPERATE YOUR CLARUS DUET WITH A LINE PROBLEM. IF THE POLARITY or GROUNDED LED
DOES NOT ILLUMINATE, DISCONNECT THE UNIT IMMEDIATELY. A LICENSED ELECTRICIAN WILL NEED TO
REPAIR THE FAULTY WIRING PRIOR TO RECONNECTING THE CLARUS DUET.

PACKAGE CONTENTS
(1) Clarus Duet
(1) Installation & Operation Guide
INSTALLATION OVERVIEW
The following is an overview for installing your Power Manager product.
•Unpack all of the contents of the Clarus Duet carton. Inspect for shipping damage.
•Plan your system and lay out all of the equipment that will be connected to the Clarus Duet.
•Place the Clarus Duet in the location where it will be used, being sure to follow both the safety precautions listed in
the front of this manual. DO NOT plug the unit in yet.
•Plug each of the components into the Clarus Duet. Be sure that the plugs are fully seated as this helps to protect
the connections from atmospheric contamination as well ensuring full contect. You may want to make a note on
paper listing the components that are connected to each outlet.
•With all of the attached components in the OFF position, plug the Clarus Duet into the wall.
•Turn the power switch to ON.
PLANNING YOUR SYSTEM
Think about which components need to work together, and place them in close proximity to one another. Be aware of
those products that generate the most heat and understand that excessive heat adversely affects your components.
Place them accordingly – allowing sufficient ventilation. You may also want to consider putting frequently handled
components in the most convenient locations. By carefully planning the system’s architecture in advance, your Clarus
Duet can be integrated into any configuration you choose.
PLACEMENT
It is recommended that the Clarus Duet be placed in the same location as your other audio components so it can be
easily reached when manually operating the other controls in the system. Since this was designed for mono block
amplifiers we suggest that it sit on the floor between the amplifier and the wall outlet. There should be a clear line of
sight between the operator and the unit to allow easy user feedback of system status. The Clarus Duet should be
placed on a flat, stable and uncluttered surface.

PLANNING YOUR AC CONNECTIONS
CONNECTING COMPONENTS TO CLARUS DUET
On the top panel there are two (2) AC outlets. For maximum performance, connect only high current components into
the HIGH CURRENT outlets. For convenience, any component may be connected into Duet’s outlets without causing
harm to the individual component. However, they may not be afforded maximum filtering and conditioning.
MAKING CONNECTIONS
All components in a system must be connected to a power conditioner in order for the system to be protected from
electrical disturbances and to achieve maximum noise filtering and line conditioning benefits. Failure to do this will
degrade system performance and leave it vulnerable to electrical damage.
TROUBLESHOOTING
Symptom
Possible cause
Solution
Clarus Duet will not
power up
The Clarus Duet is not receiving
power
1. Check that the unit is plugged in
2. Check the outlet for power
3. Check that power button is in the ON position
Circuit breaker is tripped
1. Reset the circuit breaker on the side panel
2. If the Breaker continues to trip, try moving one or
more units to another Clarus Power Block, you may
be drawing too much current.
Protection Fault LED
is on
Indicates the internal surge
protection is inoperative. This
happens when the Clarus Duet
receives multiple surges and
sacrifices itself to protect your
electronics.
1. Disconnect your electronics from the Clarus Duet
2. Contact your dealer for service
The Polarity LED is
off
This indicates that the power
cable or the wall outlet the Clarus
Duet is plugged into has it’s
polarity inverted
1. Do not operate the Clarus Duet with an inverted line;
call an electrician to have the line repaired.
There is an audible
“thump”, “click” or
“pop” coming from
my speakers during
Duet up.
This is common, while annoying,
it can happen when a preamplifier
or powers amp’s internal power
supply is being turned on. It will
not harm the loudspeakers
1. To minimize or eliminate “thumps”, “clicks” or “pops”,
program the Preamplifier or A/V Processor to turn on
before the Power Amplifiers.
