Transparent Reference PowerIsolator

REFERENCE PowerIsolator is the perfect surge-spike protection and power conditioning solution for Connoisseur Level music and film systems. It works well with ULTIMATE Companions to provide superior component isolation, and unrestricted, noise-free power.




RPI has 8 high-current US outlets in 4 isolated banks. Its parallel filter circuit design does not restrict current, and the avalanche-diode surge protection on all outlets is instantaneous and never wears out. Transparent PowerIsolator Technology results in more realizable, in-phase power than Transparent’s PowerWave Power Conditioner Series. More realizable in-phase power reduces noise promotes superior tonal fidelity and increases dynamic range.

Its hybrid extruded-aluminum and non-magnetic thermoformed polymer enclosure promotes electromagnetic field expansion and allows more fluid and robust dynamics. Internal cross bracing and additional proprietary epoxy loading damp also resonances and vibrations.

REFERENCE PowerIsolator is handcrafted in the USA and has a Transparent Connected Equipment Warranty. In addition to avalanche-diode surge protection on all outlets, it has gigabit network source surge protection and coaxial source surge protection.

REFERENCE PowerIsolator comes with a REFERENCE Power Cord for the wall outlet connection. Transparent recommends using REFERENCE Power Cords with all associated components.
