Using 2 Channels at once?
Okay, listen up. I have an old Technics SA-EX310 Audio/ Video receiver. Right now I'm using the Left channel to power my 150W RMS, 4 Ohm subwoofer. However, the amp's output RMS is only 70 Watts per channel, at 8 Ohm. I know its probably not a good idea, but it's going to have to do until I get my Crown CTS amp and my Wharfedale 18'. The amp gets WAY too hot and the 'safety' relay kicks in sometimes and cuts the signal Crown Cts because the thing gets so damn hot. I have a small fan running on the top and that seems to help... To a certain extent. Since I'm getting a new amplifier and subwoofer in the near future, there is not sense running out and spending money on a 300-500$ subwoofer amplifier. My question here is: Since I am running the amplifier in stereo mode, and have one RCA going into the left channel input, and having the subwoofer on the left channel output, you can see that it causes A LOT of stress on the amp. NOW, would it be possible to use an RCA splitter and have it split the subwoofer signal from my receiver into 2 RCA's, hook one of the 2 RCA's into the left channel, then the other one into the right channel, and then have the subwoofer connected to both the right and left channel outputs? Would that be possible? Would it destroy my amp? Any help would be MUCH appreciated. Thanks,

Hi:Congrrats on being an FOH Engineer; sounds like you have your hands full! I think this article, entitled “Mixing a stadium gig for the first time – Techniques & Tips” by Pete Thomas will be useful to you:http://www.facebook.com/note.php?note_id=123578997683174You may also want to check out Mix magazine. Here is an example of an article that you might find interesting:http://mixonline.com/livesound/tours/all-access-wolfmother-0210/Lots of websites I’ve come across in an attempt to help you are trying to sell you a piece of equipment; See, e.g., this one, that is specific for houses of worship:http://svconline.com/how/products/showcase_foh_mixers_0109/Also check out this one on digital consoles:http://www.prosoundweb.com/article/print/front_of_house_the_current_view_from_the_cockpitNonetheless, they may provide good tips (and you may want to contact them to see if they can send you some guides by email or snail mail).Lastly, here is a website that provides a case study on setting up an FOH for a church (also using a piece of equipment that the site is trying to sell). On page 2, a schematic of a set up in an historic church is provided:http://www.aviom.com/Library/Case-Studies/St_Matts_Case_Study.pdfHope at least some of this stuff was helpful!!!
