Daisy chain
Connecting several pedals or several valve heaters to one shared supply, so power is passed along a line instead of each unit having its own isolated feed.
In pedalboard use, a single adapter with a splitter cable powers a whole board, which is compact and cheap but means the pedals share a common ground and a limited current budget. Digital and high-current pedals can then introduce noise into analogue ones sharing the same line, and an overloaded supply produces hum or dropouts. Isolated supplies exist precisely to avoid that sharing, and they are the usual cure for a noisy chain.
Example: a board where adding one digital reverb brings a high-pitched whine into a fuzz pedal is usually a daisy chain problem, not a fault in the fuzz.
