Use this handy audio ground loop isolator to remove alternator whine from the JMCB-2003 or MHAS-2008/2005/2003 audio systems, that is caused by an AUX music source that has also been connected to the motorcycle’s electrical system. (bike powered satellite radio receiver plugged into the aux input is but one example of this condition)
J&M’s Isolator adapter cable simply plugs in series between the aux input plug and the aux input cable, included with these J&M units.
Adapter is made with top-quality connectors and is internally sealed for complete weatherproofing.
