The RapcoHorizon Isoline-3 Line Level ISO / Splitter Box is wired with a 3-pin hot XLR. It provides quality 1:1 line-level output transformers for applications requiring a high degree of electrical isolation. It is used in applications such as servo balancing, breaking ground loops between pieces of equipment with unbalanced lines, and floating the unbalanced outputs of a crossover unit, or an unbalanced mixer output that must run down long cables to power amp inputs.
Transformer isolation in any such situation should minimize interference from radio transmitters, lighting dimmers, and 60 Hz AC power wiring, and help goof-proof sound systems and installations from improper connections or faulty conditions.
It features a ¼” input (can be used balanced or unbalanced), a ¼” loop out with an XLR male output, a ground lift switch for buzz-free operation in almost any environment and an 18 gauge formed steel box. The connectors and the switch are recessed to resist damage.
