MC 909 Ground Pin

MC 909 Ground Pin

When I bought my MC 909, there was no ground pin on the back. I thought it had broken off, but now I hear this is a Roland design for a complete isolation circuit. Is this true? Thanks.

Come on guys, it's an easy question. Let me rephrase. When you bought your Roland MC 909, did it have a ground pin on the back or a hole where you would expect to see a ground pin?

I wanted to answer your question, but I haven't seen the ground pin on too many Roland gear. If remember right I've seen it on units which have hard drives inside.

I had mine for 5 years and never used it (just sold it on ebay) Do you have HUM/BUZZ problems? I thought it was for a POSSIBLE electric charge issue (minor shock when you touch it)......which in my case never happened either.AAAAHHHH...just looked at manual page 15! It's for the SHOCK THING...but using it MAY induce a BUZZ...:)

It's just a screw that you loosen and attatch a ground too.

I've not had any hum or grounding issues though, so I haven't used it.
