Clarus Duet Power Block

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 Duet Power Block is designed with the strength and size to support the demands of a mono block amplifier and powered subwoofers.

The Duet's high performance hospital grade outlets are engineered with advanced materials to ensure electrical contact reliability over time. 2 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.

Clarus C-Core Technology
The Clarus line of power conditioners are made with the proprietary Clarus Core "C-Core Technology" which is used in all Common-Mode 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.

The Duet protects from surges with a 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.

Top Panel Safety LED Lights
Ground and Polarity LEDs when lit indicate that the power cord and outlet to which the Duet is connected is in phase and properly grounded.
