The ARX Audiobox ISO Combiner is a single-channel, transformer-isolated passive combiner designed to solve common audio routing challenges in professional environments. It allows two balanced XLR sources to be combined into one without noise, hum, or signal degradation—ideal for applications where two signals need to share a single input.
This compact, passive unit requires no power to operate. It features a pair of transformer-balanced female XLR inputs and a single transformer-isolated male XLR output, ensuring clean, electrically isolated signal combining.
Built for real-world use, the ISO Combiner is housed in a heavy-duty steel chassis with a textured matte powder coat finish, hardwearing epoxy screen printing, and slip-resistant rubber pads. Additional installation-friendly features include a Kensington-type security slot and optional under-table mounting bracket.
