PAC SNI-1 Ground Loop Isolator

The PAC SNI-1 Ground Loop Isolator is designed to eliminate unwanted noise, such as engine whine, alternator noise, and low-frequency hum, from your car audio system. This passive audio signal isolation module works by preventing direct ground continuity between components, making it ideal for integrating aftermarket amplifiers, processors, or external audio sources.

It is specifically engineered for use with portable devices that have RCA audio outputs, including pre-amp outputs. The SNI-1 boasts a close to perfect frequency response of +/- 0.03 dB from 2 Hz to 20,000 Hz, ensuring clean and accurate audio reproduction. Utilizing proprietary audio transformers, it provides a 1.3 dB gain to compensate for any potential signal loss in the audio path. Its compact and durable housing allows for flexible installation under the dash or behind the radio.

• Eliminates ground loop noise between the audio source and radio.
