Product Advantages
● Breaks ground loops at the source: Each channel runs through a 1:1 (600:600) isolation transformer. ● True dual-channel isolation: Channels A and B each have their own independent transformer and independent jacks. ● Permalloy core with shielding can: Permalloy (Pomo alloy) transformers are housed in shielded cans. ● Dual-layer shielded circuit design: A second shield layer on the circuit 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 disconnects the ground when loops are already closed elsewhere. ● Passive design, no power supply needed: No power adapter, no active gain stages, so the isolator adds no background noise or self-noise to the signal. ● One unit for both balanced and unbalanced sources: XLR / 6.35mm combo inputs accept both signal types, while gold-plated RCA line inputs and 3.5mm AUX input cover consumer and pro-level sources. ● Built for repeated use: Permalloy silver-plated contact switches and gold-plated RCA jacks provide stable, low-resistance contact.

Applications
Professional Recording Studios & Music Production
Eliminates AC hum in monitoring and recording chains between mixing consoles, outboard gear, studio monitors, audio interfaces, and computers.
Live Sound & Stage Performance
Solves ground potential differences between stage sources (DI boxes, keyboards, playback devices) and the main FOH console or powered speakers.
Video Conferencing & Unified Communications
Isolates conference codecs, PC audio, and speaker systems in meeting rooms and control rooms.
Conference & Simultaneous Interpretation Systems
Isolates delegate microphone units, interpreter consoles, and headphones, and enables audio connection between rooms or booths.
Home Theater & Hi-Fi Audio
Eliminates audible AC hum in systems between TVs, AV receivers, and powered subwoofers or active speakers.
Installed AV Systems
For auditoriums, exhibition halls, and similar fixed installations where long cable runs and multiple power circuits tend to create ground loops.
