I am in a 4 piece bluegrassy band and we are trying to put together a PA.
I picked up a Samson D412A
active PA speaker. The second one, ordered by a fellow bandmate is in-route by fedex. We were planning to use these to grow and that they will hopefully be useful as stage monitors if we get a bigger setup down the road.
I have some MOTU gear which can apparently work as a standalone mixer (MOTU 828 mkII + MOTU 8pre) but fidding with knobs and using the 828 menus for live sound seems like a nightmare, as does bringing my laptop and trying to mix that way.
So instead I did a switcheroo at work and now the studio computer has the 8pre (simple radio show) and I have an old but reliable Panasonic Ramsa WR-133 8 channel mixer. Not the nicest but certainly more user friendly than the MOTU mixer idea.
I connected line out A on the mixer (+4db 600ohm) to the Samson speaker with XLR cable. we practiced once like this and all seemed well. The input knob on the speaker itself was about 1/3 of the way up and my output fader on the board was at about +10db no clipping sounds, no blinking of the "peak" light. Vocal mics, two guitars and one banjo mic were connected and the faders also set at about +10db with small variances.
2nd practice. we went for a little more volume since we have a show tomorrow and wanted to try the level we anticipate using inside a small bar.. nothing crazy and again, no clipping sounds or peak light. I got the extra volume by bringing the output fader up to 0db. 4th or 5th song in the speaker shuts off with it's peak light steadily lit. I'm freaking out at this point... back panel is pretty toasty so I am thinking maybe it shut off due to excess heat so we give it 15mins sitting in front of a fan and go back to our old volume level, all extremely worried about my new purchase.
2 more songs with me watching that peak indicator like a mother bear watching her cubs. It stops producing audio once again with it's peak indicator steadily lit. Now when powered on it just produces a bassy hum with peak and power steadily lit, even with no XLR plugged in.
Did I do something stupid? I read the manual thoroughly before ever hooking it up and am not a total noob, but I also have never used a powered PA speaker before.
It did take a long time to be shipped from Nevada to NY and it also was deemed "delivered" on a Thursday but I had to badger Fedex to get it to actually arrive two days later.... I WANT to believe it took a beating in shipping and this isn't my fault but I don't want to ruin the second speaker which will be arriving soon by repeating a stupid mistake. Please school me!!!
