System Often Make A Large Metal Ding Sound

"Heavy transients and bass passages" are when you have a lot of musical activity, if you will, during a passage of a song. Think of the real cannon blasts on the 1812 Overture or the first 30 seconds of Yosi Horikawa's "Intro", off of his Vapor album where you have a heavy (low frequency) bass.

A heavy musical passage is usually a bridge that uses changes in rhythm, dynamics, or instrumentation to build tension up to a crescendo that would be considered a heavy transient. These usually last for a short period of time and put a lot of demand on a system.

I do not know. It is not an electronic tone, it is physical. It may be the rack or the components but something is heating and expanding and, at variable times, some joint/interface needs to give. Sort of like a minor tectonic shift. Just my speculations.

What do you mean "joint/interface needs to give"?

All rigid structures are not perfectly rigid and junctions (joints and interfaces) are affected by thermal effect on their components.

Will the physical structure be damaged?

 

[Kal Rubinson]

So if we don't do something about it, the physical structure will be damaged. Am I right?

Nope. They expand as they warm and contract as they cool and repeat. My system is powered up almost all the time but parts of it may be unpowered for long weekends. The only time I hear the noises is after I return from a hiatus. It bothered me until I understood it.

Sounds like my steam heat as it heats and cools knocks and bangs
