Have you installed an audio source like Bluetooth, GPS, etc, and found noise through the stereo that did not previously exist?
If the noise changes pitch with the RPM’s of your engine, you have a ‘ground loop’; typical when you power an audio device off of a vehicle.
The Ground Loop Isolator (GLI) is designed to remove hiss and alternator whine from the audio signal. Our ground loop isolators use matched transformers and additional components so that you don’t lose low-end sound quality, unlike cheaper products. Available in 3 models:
03205 – Universal with 3.5mm male input and 3.5mm female output.
03207 – Honda Direct Connect with 3.5mm male input and Honda 3 pin output.
03203 – Honda Dual Direct Connect with Honda 3 pin input and Honda 3 pin output. For use with our Bluetooth, p/n 03215.
Also available: 6-foot extension cable with Right Angle Male Plug for handlebar mounting and power noise filters that can make GLI more effective in some cases.
