The amplifier's input shield connection (if properly designed) will have virtually no connection to the amplifier's power ground. These input circuits will, ideally, completely isolate the audio's shield ground from the amplifier's internal connection chassis ground.
It is an attempt to make the concept clear to those who are new to car audio.Įvery piece of car audio equipment has some type of noise canceling circuit on the audio input circuit. This next paragraph will become agonizingly redundant. These pulses create noise that varies with engine (and therefore alternator) speed. To make matters worse, the alternator produces small pulses which aren't completely filtered out by the battery and/or capacitors. If you could measure the voltage from the ground for your amplifier to the ground for the head unit, you would see a very small difference of voltage even though they are both ground. Any time that you have current flowing through a conductor (which, as you remember, has resistance) you will have a voltage drop across the conductor.Īny accessory (lights electric motors etc.) which are grounded to the body will cause varying voltages across the conductor (the body of the vehicle). This includes the vehicle's metallic chassis. You already know that ALL conductors have resistance. This means that the audio output's reference is tied to the mounting position of the head unit. The head unit's preout audio section is referenced to ground (the metal outer chassis of the head unit to be more precise). We also provide lifetime technical support by phone and email to meet all your vehicle audio needs.Ground loop isolators are used to break the DC circuit path for the audio shield ground circuit.

Stop by one of our brick-and-mortar locations for professional installation and service. Mobile sound processing accessories from are a simple solution to help produce a clean, clear signal from your radio or music player. When you’re out driving, you want to hear your favorite music, podcast or talk show - not the buzzes and hums caused by your engine.
#GROUND LOOP ISOLATOR CAR AUDIO DRIVER#
Add a ground loop isolator/audio line driver to your car and you’ll get the most out of every volt. This compensates for the signal loss that otherwise occurs across cables and circuit boards so more of that sweet, sweet audio power reaches your speakers. In addition to blocking unwanted signals, these combo devices also amplify the signal you want to hear. Some of the ground isolators we sell also contain an audio line driver. We have great brands such as Axxess and Pyle at great prices. They also can filter out engine noise and other signals that might get in the way of your listening experience. Each one uses a small transformer to step voltage up or down between devices with different outputs. Our selection includes RCA ground isolators, 1/8-inch stereo audio isolators, iPod-to-3.5mm isolators and mini ground isolators. We have vehicle ground loop isolators for sale with a variety of inputs and outputs to match your cables. By installing one at the head unit, behind the radio or at the amplifier, the only humming you’ll hear is yourself as you listen to great music. A ground loop isolator from blocks the voltage spikes that cause signal interference. If there’s interference in the audio signal that produces the annoying hum everyone recognizes, then silence will suddenly seem reasonable.
