The ARX Audibox ISO Balancer DI is a dual-channel, passive interface designed to convert unbalanced audio signals into balanced, low-impedance signals suitable for professional audio systems and long cable runs. It’s an ideal tool for eliminating ground-loop noise and ensuring clean signal transfer in a wide range of environments, including corporate AV setups, computer interfacing, and consumer-to-pro audio integration.
Transformer-Isolated Performance with Flexible Connectivity
Built around high-quality transformers, the ISO Balancer DI provides galvanic isolation between input and output, effectively suppressing noise and preventing interference caused by ground loops. Input options include 1/4", RCA, and 3.5mm stereo jacks, ensuring compatibility with virtually any consumer audio source. The balanced outputs are presented on industry-standard XLR connectors for seamless integration with professional audio equipment.
Rugged, Passive Design for Versatile Deployment
An onboard Mono'ing switch allows stereo signals to be summed to mono—particularly useful in conference or presentation settings. Housed in a robust, powder coated steel chassis with epoxy screen printing and a large non-slip rubber pad, the ISO Balancer DI is built for durability and flexibility in both fixed and mobile installations. It operates completely passively, requiring no external power, and includes a Kensington-type security slot and optional mounting bracket for secure under-table installation.
