ARX - Iso Balancer DI

by ARX

Audibox ISO Balancer DI

The Iso Balancer DI converts Unbalanced Audio signals to Balanced, Low Impedance signals suitable for use with professional equipment and long cable runs.

Transformer Ground isolation provides low-noise operation suitable for any application, preventing ground loops and other extraneous noise.

The Iso Balancer DI features industry standard 6.5mm Jack, RCA and 3.5mm Jack inputs to cover all plug types, and transformer balanced Left and Right XLR outputs.

As an added feature, for those applications including Corporate AV and Computer interfacing the Iso Balancer DI also features a Mono'ing switch allowing Stereo signals to be easily mono'd.

The heavy duty all-steel chassis is finished in attractive matt textured blue powdercoat, with hardwearing epoxy screen printing and a large slip resistant rubber pad underneath.

The Iso Balancer DI is a totally passive device with no power requirements, making it a truly universal problem solver.

Security features include Kensington®-type computer lock slot and optional bracket kit for under-table mounting.
