## Overview

The PAC SNI-1 Noise Isolator is a compact, universal device designed to eliminate ground loop noise in audio systems with RCA outputs. Featuring a near-perfect frequency response of ±0.03 dB across 2 to 20,000 Hz and proprietary transformers providing a 1.3 dB gain, it ensures clean, high-fidelity sound. Ideal for car stereos and portable audio setups, it’s a must-have for anyone seeking professional-grade noise reduction with effortless installation.

## Description

PAC SNI-1 Noise Isolator. Eliminates ground loop noise between the audio source and radio. For use with portable devices that have RCA audio outputs, including pre-amp outputs. Close to perfect response of +/- .03 db from 2 to 20,000Hz. Utilizes proprietary audio transformers for a 1.3 dB gain.

Review: Greatly reduced noise and removed engine whine - I used two of these in my 2001 Lexus ES300 (One for each rca channel). I upgraded the radio to a Kenwood without bypassing the amp and i was getting engine whine noise. I added these and the noise went away by about 90%. The engine whine was gone but a faint noise could still be heard. Overall it may help if you're doing an audio install on an older car and hear engine whine.
Review: Actually worked , Godsend - Thought I was doomed with my infinite ground loop. Tried all types of routing and rerouting on my Harley Road Glide radio and audio system. Tried this simple device out hoping for the best and voilà !!! groundloop magically gone completely!!! what took days to try and rid this device literally took seconds to solve the problem. I’m baffled. I’ll definitely keep one of these in hand for future audio hook ups.

### ⭐⭐⭐⭐⭐ Solve your interface!
*by D***R on September 6, 2025*

Had an alternator whine in my audio system and could not for the life of me figure out where it was grabbing the signal from. I bought this and installed and the issue was immediately gone. This product works and is easily wired in and hidden. Excellent sound quality still coming through as no grainy noise was heard and it’s small lightweight allows it to be hidden easily. Would buy again if needed.
