2-Channel Ground Loop Noise Isolator | Gold Connectors, Braided Cable

Clean Up Your Audio Signal with the CACAZI 2-Channel Ground Loop Noise Isolator

Unwanted hum and buzz in your audio system? The CACAZI Mini Ground Loop Noise Isolator is an inline passive filter designed to eliminate ground loop interference across two audio channels — no power required. Whether you're running a car stereo, home theater, mixer, or recording setup, this compact isolator slots neatly between your source and output to deliver cleaner, clearer sound.

Key Features

• 2-Channel Inline Design: The central isolator module sits between left and right channel leads, splitting the route while keeping your wiring layout clean and easy to follow.
• Ground Loop Hum Reduction: Place it in setups affected by ground loop hum or current interference to significantly improve audio playback across linked components.
• Gold-Plated Connectors: Red and silver dual-channel connectors with gold-plated pins ensure a reliable, low-resistance connection and long-lasting performance.
• Braided Cable Sleeve: The woven exterior adds durability and a tidy, professional appearance to your wiring.
• No Power Needed: Install inline between your source and output — no additional adapters or power supplies required.
• Wide Compatibility: Works with car stereos, AV receivers, mixers, speaker systems, TV boxes, multimedia players, and microphone setups.

Frequently Asked Questions

Q: What is a ground loop noise isolator and how does the CACAZI 2-channel inline filter work?

A: A ground loop noise isolator is a passive inline device that breaks the ground loop current path between two connected audio components. The CACAZI 2-channel isolator uses internal transformer-based circuitry to electrically isolate the audio signal, filtering out the hum or buzz caused by differing ground potentials — without requiring any external power source.

Q: What devices is this 2-channel ground loop filter compatible with?

A: This noise isolator is compatible with a wide range of audio equipment including car stereos, home theater AV receivers, mixers, multimedia players, TV boxes, speakers, and microphone systems. It supports any setup using standard RCA or compatible inline connectors where ground loop interference is present.

Q: Will this ground loop isolator affect my audio quality or signal strength?

A: The CACAZI noise isolator is engineered for minimal signal loss — fixed insertion loss is less than 0.7 dB at 1 kHz, and the frequency response spans the full audible range (20 Hz to 20 kHz). In most listening environments, the improvement in hum reduction far outweighs the negligible signal attenuation.

Q: Do I need to plug this isolator into a power source to use it?

A: No. This is a fully passive inline device — simply connect it between your audio source and output equipment. No batteries, power adapters, or additional accessories are needed.
