Passive Stereo DI Ground Isolator

Physical specs: 12 cm length × 8 cm width × 4 cm height; net weight 320 g; housing material: anodised aluminium alloy; input: mono 6.35 mm jack + XLR male; output: stereo XLR female; impedance: 600 Ω (both input and output, AC-coupled); grounding controls: dual-channel (L/R) + global ground switch. Engineered to suppress low-frequency ground loop noise and high-frequency interference from shared power supplies or long interconnects — common in UK-based home studios, church sound systems and small venue installations. Delivers transparent signal transfer with no gain staging or power requirement. Compatible with line-level outputs (keyboards, synths), instrument-level sources (guitars, basses), and microphone inputs (dynamic only). Widely used with Behringer, Allen & Heath, Yamaha, and Soundcraft mixers; also integrates well with QSC, EV and JBL powered speakers. Requires external phantom power for condenser microphones; unsuitable for digital audio transmission or console-based voice chat applications.
