Application Specifications
A ground loop appears whenever two devices powered from separate supplies are joined by a signal cable.
| Application Category | Target Scenarios | Key Function & Benefit |
| Car Audio & In-Car Entertainment | AUX-in head units, aftermarket radios and car amplifiers fed | Breaks the ground loop formed between the vehicle electrical system and the portable device |
| Home Stereo & Hi-Fi | Amplifiers, AV receivers, active | Eliminates 50/60 Hz mains hum caused by different ground potentials |
| Portable & Mobile Devices | Smartphones, tablets, MP3 players, portable DAC | Noise-free playback from battery-powered devices |
| Desktop, Streaming & Content Creation | PC or laptop audio feeding monitor speakers | Removes the ground noise that appears when computer and speakers |
| Commercial & Institutional Audio | Retail and showroom background music players | Keeps program audio clean and intelligible |
Product Features
● Eliminates ground-loop induced hum and buzzing noise while preserving original stereo audio quality
● Shielded casing structure resists external electromagnetic interference
● Professional built-in audio isolation transformer delivers excellent audio-isolation performance
● Plug-and-play design requires no extra power supply or drivers for quick installation
● Robust metal-compatible shell structure ensures durability
● Supports stereo XLR audio signal transmission with wide compatibility
Product Advantages
● Removes ground-loop hum at its source. The built-in 1:1 audio isolation transformer breaks the direct electrical connection between the two devices while still passing the audio signal.
● Keeps the original stereo sound. Isolation is magnetic rather than electronic - no EQ curve, no noise gate, no added hiss.
● Fully passive - no power, no battery, no driver. The unit draws nothing from the source device or from the vehicle electrical system.
● Compact inline body that stays installed. A 59 x 20 x 18 mm molded housing with strain-relieved cable entries sits in line with the existing cable and disappears behind a dashboard or under a desk.
● Isolation transformer wound in-house by an ISO 9001 factory. The transformer stage is produced on the same lines as ZXY's audio transformer series rather than bought in as a commodity part.
Application scenario
Application
Isolation principle
A passive 1:1 audio isolation transformer transfers the audio signal magnetically across the isolation barrier.
Compatible equipment
Car stereos, phones, tablets, MP3 players, Bluetooth receivers, amplifiers, speakers, soundbars, mixers, and other devices.
Installation & operating conditions
Passive construction generates no heat and needs no ventilation, so the unit can run continuously in a vehicle cabin, a home listening room, an office desk or a portable rig.
Mechanical construction
Molded black housing with a metal-collar output jack and molded strain relief at both the housing entry and the plug.
