Look at the signal cabling or even nearby EMF sources. I recall ages ago
having a Dbx 160 compressor in a rack under a Klark Teknik DN27 graphic
EQ with a small but noticeable hum in the speakers. Separating these by
1 rack space cured the hum!
And some equipment just hums by itself anyway, especially as it ages.
