Do something practical then. Keep your amp on, and switch on/off your DCB1 so we know if you get the hum by any chance. In my system I tried. Niet.

What amp you got? Zin? Loud hum?

P.S. There was another way posted by Oenboek. He wanted no relay contact so he did an easy change and used the relay to ground short instead.

''I bypassed the delay relais as I don't want this contact in the loop. I use the relais to ground the signal. This is a very easy change on the PCB. Just connect the 2 unused pins of the relais-switches to the ground, and link the middle and output pins of the switches together (by channel off-course).''

So you can try that (thanks to Oenboek), for anybody who gets the thing or just feels better losing yet another signal path contact, or whatever Andrew may suggest if he will be so kind. Sorry I can't tell more since I don't get the issue so to experiment on it.

I also get this Hum(more like a buzz on mine) when i shut my dcb1 off and the power amp is still on. My poweramp is a tubeamp and has a 1meg Zin.
I get around this simply by switching off my poweramp before i turn off the dcb1.

Not extremely loud...but loud enough to want to quickly turn off the poweramp.

Wanna beta test the Oenboek's grounded cross? Maybe it has a quality notch side benefit by skipping the contact too. The photo is tell tale.
