Clarus Duet Two-Outlet High-Performance Power Block

Clarus designed the Duet Power Block with the capability to support the demands of Monoblock amplifiers, powered subwoofers, and powered speakers. The Duet Power Block features high-performance hospital-grade outlets engineered with advanced materials to ensure electrical contact integrity and reliability over time. Two HIGH-CURRENT outlets deliver clean AC power filtered by the sophisticated Clarus High-Current Core (HC-Core)—providing full power without restricting dynamics.

HC-Core Technology for the Lowest Possible Noise Floor

The Duet features proprietary Clarus High-Current Core (HC-Core) technology. Made with nanocrystalline soft magnetic (ferrite) material, the high saturation magnetic flux density and high permeability of Clarus-Core produce a high impedance resulting in excellent noise suppression over a wide frequency range. Furthermore, Clarus HC-Core exhibits near-zero effects of magnetostriction—a property of ferromagnetic materials that causes them to change shape or dimensions during the magnetization process. The low magnetostriction of Clarus HC-Core significantly reduces audible noise emission when the applied voltage and current are in the audible frequency range. No other core performs as well to keep your AC signal silent and clean.

Three Levels of Protection and LED Safety Lights

Duet features a layered fail-safe system that will protect your audio investments. A thermal breaker is built into the input of the Duet Power Block, protecting from overcurrent conditions caused by excessive loads or equipment short circuits. Highly sophisticated Thermal Metal Oxide Varistors (TMOV) provide 480 joules of surge suppression with an integral temperature sensor designed to trigger a relay. If the TMOV reaches a critical temperature, this relay disconnects the power. If the surge suppression circuit is compromised, the front panel Protection Fault LED illuminates, and the unit shuts down for safety. Additionally, ground and polarity LEDs indicate that the power cable and outlet to which Duet is connected are in phase and properly grounded.

Duet Will Not Limit Current

The Duet Power Block delivers full power without restriction. We recommend using a power cable that does not limit current. The CCP-HC Crimson High Current Power Cable or the CAP-HC Aqua High Current Power Cable are excellent choices. Power cable sold separately.
