Today was supposed to be Fun Piano Play Day, but instead it turned into Heart Attack OMG day, because one of my speakers developed a nasty buzz.
I hooked up the shiny new Casio Privia PX350 digital piano to my PA system today. That’s right, piano players like to crank up the volume. As we should, because the full name is pianoforte, which means “badass loud piano”.
The PA system is a Yamaha 512SC powered mixer hooked up to a pair of Behringer Eurolive B215XL speakers. These bad girls are two-way speakers with gigantical 15″ woofers. I got a nice buy on a warehouse-resealed pair at zZounds, and I’m pretty happy with the whole outfit. It’s plenty of power and volume, and good enough bass so I don’t need a subwoofer. Everything is lightweight — the mixer is under 20 pounds, and the speakers are about 35 pounds each.
Sadly, this bad girl was buzzing like crazy whenever I played C1 or G1 on the piano, like a loud angry bee. So I did all the usual fiddling and swapped cables and played with settings, which had no effect. When a speaker buzzes at specific frequencies that usually indicates hardware resonance, which is a loose thingy vibrating. So I was thinking I would have to open it up and look for loose thingys. Yes, it has a 3-year warranty, but shipping it to a service center costs a lot of $$.
Well there I was all sad, when Terry (my fab wife) came home, and her years of playing in bands with grouchy stubborn old codgers who abuse their equipment paid off: she checked the knobs on the speaker stand, and that’s all it was– a loose knob. Tighten it up, and presto! No more buzz. Life is good and I am happy again.
