Hi all,
I have just bought a Realistic Equalizer, model 30-9081 new, never used!
Plugging it into my Yamaha receiver with quality RCA cables I realize that a very audible amount of hum is coming out of my KEF speakers. If I play with the 31 to 250 Hz sliders, on both channels the hum gets more audible, but the other sliders (higher frequencies) don't add any noise to the sound...
I have disconnected everything in my studio, having just the EQ and amp plugged in the same ac strip, and even tried with another amp and its the same.
It must be the EQ... it is new but due to age maybe the sliders need a good clean with a proper contact cleaner?
with the low frequency sliders at Zero the spectrum is already showing a lot of activity... while I am playing a pretty flat sounding acoustic song... thats the hum...!
Any tips?
thanks for your help!
