Members ggoroni Posted July 27, 2005 Members Posted July 27, 2005 hi bros, i got a SWR 350 head and two cabinets, a SWR Triad 1 and an EBS 410 i've just bought. now, when i play outdoor i wanna try "the tower" (ie the two cabinets together): shall i use the two outputs i've on my head or the one i've on my cabinet? which way is best? which one more powerful? i was told there are some heads (hartke i think) that have two 350 watts outputs (so that if you use two cabs the final output is 350 X 2), but i don't think this is the case for my head...suggestions? anyone else has the same head? thank ya dudes!
Members Rippin' Robin Posted July 27, 2005 Members Posted July 27, 2005 whichever way you wire it up, you won't get more than 350 watts.

Well, depends on what you mean by "the other way". If this means HEAD -> CAB1 -> CAB2, than it doesn't really matter. Personally I prefer to plug both cabs into the head. If anything happens to the first cab, the second cab is going too.

Hey how about getting a cheap second hand rackmounted power amp? If you like the sound of your SWR it's the cheapest option to get massive amounts of power.

Hey how about getting a cheap second hand rackmounted power amp? If you like the sound of your SWR it's the cheapest option to get massive amounts of power. yeah, now that's a good idea! i'm sorry for my extreme ignorance bout amps, the swr was my first REAL amp... wait a minute, now a silly question (by a silly bassist): the final amount of power of the cabinets is given by the sum of every cab? i mean, if i have say a 1200 watts head i can use a 400 watt cab + a 800 watts one? i know i must sound stupid, but i thought that this would "overdrive" the cabs! hope you see what i mean! d'you mean that the head has a sort of "crossover" which delivers the power according to the cab without overdriving it? thanx dude, you're teaching me how to live!
Members Rippin' Robin Posted July 27, 2005 Members Posted July 27, 2005 Hey ggoroni, you need to read this FAQ thread: http://acapella.harmony-central.com/forums/showthread.php?s=&threadid=295472 About the power, it's like pouring water into two bottles ogf a different size but with the same size opening. The amp doesn't know what cab is what, so a 1200 watts amp will deliver 600/600 to either cab.

Members ggoroni Posted July 27, 2005 Author Members Posted July 27, 2005 hey robin, what power amp woud you suggest me?
Members Rippin' Robin Posted July 27, 2005 Members Posted July 27, 2005 Originally posted by ggoroni hey robin, what power amp woud you suggest me? anything peavey would be right on the mark. Indestructible, cheap and lots of power. Or Yamaha. I don't know what kind of brands you can get over there...

If this means HEAD -> CAB1 -> CAB2, than it doesn't really matter. If you took apart the head, you would see that (in most cases) there are two small (prob. 16 gauge) wires (three or four inches long) that connect output jack1 to output jack2. One jack is connected to the wires delivering the power, and the second jack is usually just tapped onto the first. Unless you have a stereo amp, connecting two cabs together or connecting two cabs seperately makes no difference. Now, having said that, there are/were some amp mfgs. that wire their jacks in SERIES, but it will state that directly on the back plate. Otherwise, the two will be connected PARALLEL, the same as connecting the two cabs together. It makes no difference to the amp. QUESTION: Have you stacked your tower and played through the SWR350? It might just surprise you how loud it is without adding a second amp.

Underpowering is a misnomer. When you are underpowered, you don't have enough power for the situation you are in so you just keep turning up and up and up. Well, eventually your amp will start to clip, sending very high spikes of wattage in the form of square waves to your speakers, which will kill them in one way or another.
