Clarus Concerto

The Clarus approach to power conditioning represents a radical new way of designing an application specific filtered AC energy delivery 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 signal 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 Concerto is Clarus’ flagship Power Conditioner.

The Concerto’s high performance hospital grade outlets are engineered with advanced materials to ensure electrical contact reliability over time. Each duplex outlet is isolated to prohibit interaction between adjacent outlets. Outlet banks of the Concerto are labeled specifically with the appropriate component-type that will provide the highest level of filtering.

  • •    2 outlets labeled: HIGH CURRENT incorporate a Massive 30A Clarus-Core filter to deliver full power without restricting dynamics to high current equipment like power amplifiers, receivers and powered subwoofers.
  • •    4 outlets labeled: DIGITAL connect to filters that are specifically designed to deliver clean power to Digital Audio equipment like DACs and CD players. Clarus’ proprietary design of complex multi-level filtering offers the best attenuation of noise while not restricting dynamics.
  • •    2 outlets labeled: ANALOG connect to filters that allow analog music to bloom. Engineered with Clarus Core or "C-Core" filters ensure there is no restriction of dynamics. The technologically advanced C-Core has superb magnetic properties that performs and sounds better than any analog audio filter available.

Clarus C-Core Technology
The Clarus line of power conditioners are made with the 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.

Vibration Control
A low frequency AC signal passing through the copper windings of an inductive filter can result in a mechanical vibration. To prevent these vibrations from becoming audible the Concerto model incorporates vibration dampening material providing a dead quiet base.

Under/Over Voltage Protection
Over/Under voltage protection provides an audible alarm and auto shut-down when voltage drops below 90VAC or above 135VAC protecting your precious audio components. When safe voltage returns the Concerto can return to the last power-on state by pressing the front power switch. Alarm can be switched on/off.

The Concerto 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 and Polarity LEDs when lit indicate that the power cord and outlet to which the Concerto is connected is in phase and properly grounded.

Cable Support
The Concerto provides a cable support system to easily handle the heaviest High Current power cable.
