The ARX Audiobox ISO Later DUO is a passive, dual-channel, transformer-isolated de-coupler designed to eliminate ground loop hum and provide complete galvanic isolation in professional audio systems. Ideal for broadcast feeds, remote recording setups, and other critical signal paths, it ensures clean, interference-free audio by physically isolating input and output grounds—without the need for external power.
Whether you’re dealing with troublesome hum or need a rock-solid solution for signal isolation, the ISO Later delivers consistent, noise-free results in a rugged, installer-friendly form factor.
Built for Demanding Audio Environments
Housed in a heavy-duty, all-steel chassis, the ISO Later is made to handle the rigors of mobile setups, studio installs, and field applications alike. The matte textured powder coat finish resists wear, while slip-resistant rubber feet keep it stable on any surface. All components, including the ultralow-noise audio transformer and fiberglass PCB, are designed for long-term reliability and audio transparency.
No Power, No Problem
Because it's completely passive, the ISO Later requires no batteries or external power supply. That makes it a universal drop-in solution for virtually any pro audio scenario where isolation is needed-just plug it in and go.
Installation-Ready Features
For permanent or semi-permanent installations, the ISO Later includes practical mounting options. A Kensington-type computer lock slot offers added security, and an optional under-table mounting bracket is available for discreet setups in conference rooms or studios.
