Amplifiers Amplifiers - Grounding When two or more devices are connected to a common ground through different paths, ground path noise, or a ground loop can occur. A potential difference between these two grounds can cause unwanted noise voltage in the circuit paths.

Grounding an audio amplifier - correct signal references. Grounding is a catch-all label for a number of different topics, which IMHO is confusing. The topics are: Current routing (especially power currents, e.g. power supply or speaker connection); Correct signal reference points (a.k.a. "signal grounds").

One of the sure methods to reduce hum and hiss pickup is to attach a 3(three) core audio shielded cable or 2 no.,s of 2(two) core audio shielded wire for stereo audio amplifier input. The two core wires carry the audio signal while the shielding only after getting connected to mains ground directly, will shield the signal from external hum and hiss noise(50Hz-60Hz).

How to practice best grounding – PS Audio
https://www.psaudio.com/ps-how/how-to-practice-best-grounding/
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.
Amplifier Grounding - Tubelab
http://tubelab.com/safety/amplifier-grounding/
The proper grounding scheme of a vacuum tube amplifier has been the subject of many debates, blogs, forums, and web pages. There are actually two important aspects related to proper grounding, hum reduction, and safety. The safety aspect is often overlooked, or ignored in the quest to eliminate hum. With careful design it is possible to satisfy both criteria simultaneously.
Grounding and Shielding for your DIY Audio Projects
http://diyaudioprojects.com/Technical/Grounding-Shielding/
In a typical piece of audio equipment (most everything else as well) there are usually three distinct ground circuits. The first is obvious, the signal ground, the second is the power supply ground and third and often ignored is the case or chassis ground. Each has a …

audio circuit ground does not necessarily have to be connected to planet Earth. The entire amplifier circuit could be built ‘floating’ inside the metal chassis, with no connection to the chassis at all. However, in reality the circuit will be connected to chassis at some point since this ensures the amplifier’s working voltages are properly

8 Power Supply Earth/ Ground. Power supplies are usually earthed to the chassis, but in some cases the DC side may be left floating, or grounded using a loop breaker (see next section). The important part is exactly where you choose to join the supply zero volt (earth/ ground) point to the chassis. With any power supply, the transformer's ...
