Radial Pro-Iso

The Radial Pro Iso is a high-quality audio isolator designed to eliminate ground loop hum and noise in professional audio setups. This compact device features two completely isolated channels, each with a high-performance transformer that provides galvanic isolation between input and output. The Pro Iso uses balanced XLR connections and includes a ground lift switch to further reduce noise in problematic installations. The transformers are carefully selected to maintain signal integrity with minimal phase shift and frequency response variation, making it suitable for studio, live sound, and broadcast applications. The rugged steel chassis ensures durability in demanding environments, while the compact footprint allows easy integration into rack systems or pedalboards. With a frequency response of 10 Hz to 50 kHz and dynamic range exceeding 120 dB, the Pro Iso preserves audio quality while effectively breaking ground loops. The device is passive, requiring no external power, and works with both line-level and microphone-level signals. The Radial Pro Iso is a reliable solution for engineers and musicians seeking clean audio without interference.
