Radial Engineering Twin Iso

The Radial Twin-Iso is a high performance two channel balanced line-level isolator for professional touring, sound installation, broadcast and studio that provides isolation between various pieces of audio equipment such as consoles, amp racks, remote towers and recorders as a means of eliminating hum and buzz caused by ground loops.

Central to the Twin-Iso are two high performance Eclipse transformers. These stellar audio engines are modelled after Deane Jensen's original designs to deliver an exceptionally linear response at all frequencies and are capable of handling as much as +21dB without distortion. Placed in between the audio source and destination, they assure absolute signal integrity is retained no matter what the program material.

As with all Radial products, the Twin-Iso is road-ready to handle the most abusive environments. It features 14 gauge steel I-beam construction and an innovative book-end design that creates a protective zone around switches and connectors. A full bottom no-slip pad provides mechanical isolation from vibrations while adding electrical insulation between electrically charged devices. When combined with the J-Rak or J-Clamp, the Twin-Iso easily integrates into 19" rack systems or may be permanently mounted inside racks or under podiums.

The Twin-Iso solves noise problems with plug & play simplicity while delivering exceptional audio signal integrity.
