Feature Highlights: 1. Dual-Channel Professional Isolation – Uses premium audio-grade isolation transformers to ensure clean, uninterrupted signal transfer. 2. Flexible Input/Output Options – Supports both balanced (XLR) and unbalanced signals. Convert unbalanced inputs to balanced outputs, or keep signals balanced throughout. 3. Ground Separation Switch – Each channel includes a ground lift switch to eliminate hum and noise caused by ground loops or voltage differences between devices. 4. Noise & Interference Protection – Isolates AC noise, prevents potential damage from high voltage differences, and ensures secure audio transmission over long distances or between mismatched equipment. 5. Wide Application Range – Ideal for live sound, conferences, installations, entertainment venues, and other professional audio setups where clean signal cascading is essential. Product Details: This dual-channel passive audio isolator is built with high-quality materials to deliver reliable performance in demanding environments. It helps remove ground-loop hum, reduces interference from mismatched impedance, and protects your gear from voltage spikes. With its sturdy aluminum alloy housing and straightforward XLR connections, it’s both durable and easy to integrate into any sound system. No power required—just connect and go.
