Hall GLI-RCA Stereo Audio Ground-Loop Isolator and Filter with RCA Connectors

Remove distracting hum and protect audio integrity in AV and security installations with the Hall Technologies GLI-RCA Stereo Audio Ground-Loop Isolator and Filter. Designed as an inline Analog AV Cables solution, the GLI-RCA eliminates ground-loop noise between any RCA-equipped audio source—DVD players, notebook PCs, mixers or surveillance recorders—and your amplifiers, TVs or monitoring stations. Using proprietary 1:1 audio transformers and precision filters, it delivers a near-perfect frequency response of +0.03 dB from 20 to 20,000 Hz while maintaining source/load impedance so your system’s tonal balance remains unchanged. The molded male RCA inputs and female RCA outputs make deployment fast and foolproof; built-in DC blocking capacitors protect transformers from output bias voltages for stable, AC-coupled outputs. Compact ABS construction and CE/FCC/RoHS certifications make the GLI-RCA ideal for commercial AV, CCTV, security audio feeds and conference-room presentations where clear, reliable sound matters. Add the Hall GLI-RCA to your AV or surveillance setup to eliminate buzz and ensure intelligible monitoring—order now or contact our sales team for volume and installation support.
