Gold plated connectors – Solid metal alloy with a 24 carat gold plating to ensure optimum signal transfer. The isolation circuit will effectively eliminate alternator and engine noise caused by ground loops for the best sound quality possible. This electrically isolates the various components of the audio systems. The 'Ground Loop Isolator' advanced circuitry uses dual high quality audio transformers with other passive components. Transformers are usually very effective at isolation and breaking ground loops, but audio transformers good enough for professional or hi-fi applications can cost 20 and up each. Lesser quality isolators have limited frequency response, which will degrade the sound quality of the system. This can oscillate, creating a whine or alternator noise coming from the speakers. How it works - Differences in ground potential of the audio components can create a ground loop. It can also be used with household devices to remove hum and it is particularly useful with laptops. It is commonly used in cars to eliminate engine and alternator noise caused by ground loops in your system. Ideal for - use between the source and amplifier to isolate the ground and filter the signal to prevent noise and hum.
