delmar Posted November 2, 2018 Share Posted November 2, 2018 I have an Ace Tone Top-7 organ. The volume pot didn't work when I bought it, so I had it repaired. They said they checked all the connections. I checked it when it got back and it seemed fine. Several months pass, and I didn't use the organ. When I plugged it into my Apollo Twin one evening, there was an extremely loud shorting-out sound that I thought would kill my monitors or the Duo. It was brief, but now I don't really trust the situation. I don't have an amp to use to attempt to recreate the problem. Should I risk plugging it into the Apollo again and wiggle cables?

Tom Williams Posted November 3, 2018 Share Posted November 3, 2018 This is almost a continuation of the recent DI thread. If your Ace Tone (egad, I remember those) was on a different electrical circuit from the amp, that might account for the hum. Given the age of the Ace Tone, I assume it is only a two-wire power cord. If your amp can take an XLR (like a mixer) input, you might consider a direct box with a ground lift feature. -Tom Williams {First Name} {at} AirNetworking {dot} com PC4-7, PX-5S, AX-Edge, PC361 Link to comment Share on other sites More sharing options...

delmar Posted November 3, 2018 Author Share Posted November 3, 2018 Thanks for the suggestion, but I expressed the sound poorly. It wasn't a hum, it was a very short, extremely loud sound like a guitar unplugged from a loud amp. Link to comment Share on other sites More sharing options...
tarkus Posted November 5, 2018 Share Posted November 5, 2018 A blast of hum is usually good for an old organ... Link to comment Share on other sites More sharing options...
J. Dan Posted November 5, 2018 Share Posted November 5, 2018 Plug the cable into the organ first, then the amp. Either that, plug the cable into both ends BEFORE turning on the amp.

Bif_ Posted November 5, 2018 Share Posted November 5, 2018 I wouldn't think this is possible if the volume is turned all the way down on the amp when plugging in. I always do this with any amplifier/speakers I own to prevent the possibility of this occurring.
