Hi all
I was wondering if someone could explain to me what is happening with this interference and how I might go about decreasing it. Any suggestions on how I might improve setup overall would also be appreciated.
I have an instrument lead unplugged and there is an audible hum in my headphones (HD-25) when i point the lead at the monitor of my iMac it stops dead also the external hard drive boxes, the 003 rack and the speaker amp. Gets louder and pitch changes when i point at my Roland electronic drums- switched off and changes pitch when i point at the modem/ voip phone. I have used another lead to check it wasn't that.
When i attach the lead to my acoustic guitar (maton with AP5 active pickup) it still hums away at roughly the same volume and pitch. Which is the annoying thing I would like to decrease hum on.
i have turned everything off except the preamp and monitor and still get the hum. Running an Apogee Mini-Me into a 003 rack via spdif cable.
Regards
