Product Advantages

● Breaks ground loops at the source: each channel runs through a 1:1 (600:600) isolation transformer.● True dual-channel isolation: channel A and channel B each have a dedicated transformer and their own connector.● Permalloy core with shielding cover: the Permalloy (Pomo alloy) transformer sits inside a shielding can.● Double-layer shielding circuit design: a second shielding layer on the board protects the audio path from EMI and RFI in racks, studios and installed AV systems.● Switchable ground lift: the front-panel GND / LIFT switch breaks the ground connection when the loop is already closed elsewhere.● Passive design, no power supply: there is no power adapter and no active stage, so the isolator adds no noise floor or self-noise of its own to the signal.● Balanced and unbalanced sources on one box: combo XLR / 6.35mm inputs accept either type, while gold-plated RCA line inputs and a 3.5mm AUX input cover consumer and pro sources. ● Built for repeated use: Permalloy silver-plated contact switch and gold-plated RCA plugs give stable, low-resistance contact.

Application

Professional studio and recording

Between console, outboard gear, monitors, audio interfaces and computers to remove hum from the monitoring and recording chain.

Live sound and stage

Between stage sources (DI boxes, keyboards, playback) and the FOH console or powered speakers, where stage power and audio grounds differ.

Video conferencing and unified communications

Isolating conferencing codecs, PC audio and speaker systems in meeting rooms and control rooms.

Conference and interpretation systems

Isolating delegate microphone stations, interpretation consoles and headsets, and linking audio between rooms or booths.

Home theater and hi-fi

Between TV, AV receiver and powered subwoofers or active speakers, wherever a hum is audible in the system.

Installed and fixed AV systems

Auditoriums, showrooms and similar fixed installations, where long cable runs and multiple power circuits make ground loops likely.
