VL Audio V-BOX PROGUARD: Passive Stereo DI Box with Advanced V-PROTECTOR™ System Protection

The VL Audio V-BOX PROGUARD is a high-performance passive stereo DI box designed to do far more than standard signal conversion. Equipped with proprietary V-PROTECTOR™ technology, it actively shields your sensitive gear by intercepting reverse currents, power surges, and accidental Phantom DC voltage before they can reach and damage your expensive mixers, power amplifiers, or active loudspeakers. Designed to protect without compromising sound quality, the V-BOX PROGUARD delivers an exceptionally flat frequency response of 20 Hz to 20 kHz (±0.001 dB) with ultra-low distortion of just 0.0011% at 0 dBu. It also completely eliminates annoying ground loop hum and buzz, offering true plug-and-play operation with no external power or battery required.
