Output #1 buzzing

Tell Tommy · Post by **Tell Tommy** » Tue Sep 30, 2008 6:53 am

I use the outputs of my TR in three ways. My left mono goes to my keyboard amp, my #1 out goes to my bass amp (I switch between playing key bass and bass guitar) and my #2 out goes to my drummer for the click track. I'm having a problem with my #1 out. It has an intermittent buzz, very much like a 60 hz hum.

Has anyone experienced this and how was it rectified. I don't have the time to send it away to a dealer, so if there is an easy fix, I'd appreciate knowing about it.

Switch output 1 with output 2, sending click to 1 and bass lines to 2. If the same thing happens with output 2, the problem is with the Bass amp, not the keyboard. Could be a ground loop. Are they all hooked to a single powerstrip on one wall outlet, or different wall outlets? Does the problem occur when only the bass amp is attached?

I've performed all the standard tests and the buzz is exclusive to #1 out. I have a strong background in electronics (worked for Hammond Organs in Toronto) so I believe I covered all the bases. I've even taken it apart to see if it might be a cold solder joint, but no luck there. The intricate electronics inside are too hard for me to trace without a schematic.

I've done all the things you've suggested and thanks for your reply xmlguy. I was hoping to see if anyone else has experienced this as well and what the particular cause was. I'm guessing it has to do with the #1 out amp in the keyboard itself, but, like I said, it's impossible to find it on the circuit board without a schematic.

Oh well, sounds like something got fried on that output.

You could move the bass to output2, and then replace the click track using a metronome with midi-sync. That might work better anyways, since you don't have to setup the click track on the keys. Or maybe having a buzz on the click track isn't a problem.

Not a bad thought. Drummers are generally deaf anyway. Let me ponder that one. Thanks. By the way, do you know how to tell a drummer's snare is level? Drool drips down all sides evenly

I wish I could persuade our drummer to use a click track. As it is, we generally get 20 beats to the bar faster by the end of the song than we started... *sigh*

This is way off topic ... but ... my drummer is 50 ( as am I ... almost) and has a hard rock background. It took him about a month to get used to the click. After a year he is so used to it, he's doing vocals, fills ... . Every musician should know how to play with a metronome. It's just a part of the scheme.
