Audio Grounding Schemes - Basic Car Audio Electronics

Chassis Ground. If you've ever installed a car audio system with multiple amplifiers, and signal processors (eqs and or crossovers), you've more than likely had to deal with noise. Noise is generally caused by ground loops (2 or more paths for the ground connection). This is why virtually all audio manufacturers have the audio shield ground ...

Signal-grounded shields on balanced equipment create ground loops in the audio path and modulate the audio signal ground, distorting most systems. This practice penalizes those who want to realize the superior performance of balanced interconnections and has given balancing a bad reputation.

ground loops in the audio path and modulate the au-dio signal ground, wreaking havoc with most systems. This practice penalizes those who want to realize the superior performance of balanced interconnections and has given balancing a bad reputation. A third possible reason for signal-grounded bal-anced shields arises if designers change phantom

The first effective grounding scheme is a system with all Class 1 components shown in figure 3.7-1. This is the grounding scheme that we developed in section 3.2. This interconnection scheme has a single-level ground system with all of the signal shields and safety grounds connected to the system star grounds.
How to practice best grounding – PS Audio

Most well designed audio equipment utilizes star grounding internally, but when you hook together products as a system, it’s best to try and utilize one ground point if possible. Dedicated AC lines form star grounds. In the PS Audio Music Room we have multiple grounded AC receptacles on dedicated lines.

Therefore, in audio, the most common practice has been to adopt the "single point" grounding scheme, where all subcomponents share a common internal grounding point , e.g inside an amplifier. If your pre and power amp are both connected to safety ground via the power connector, the ground loop is closed around the signal cable, and --there the old humming …

sciously, connect balanced shields to audio signal ground-pin 1 for three-pin (XLR-type) connectors, the sleeve on ¼-in (6.35-mm) jacks. Any currents induced into the shield modulate the ground where the shield is terminated. This also modulates the signal referenced to that ground. Normally great pains are taken by circuit

Many audio manufacturers, consciously or unconsciously, connect balanced shields to audio signal ground; pin 1 for 3-pin (XLR-type) connectors, the sleeve on 1/4" (6.35mm) jacks. Any currents induced into the shield modulate the ground where the shield is terminated.
