   Thanks everyone. I'm really anxious to get the speaker array set back up and have some of my geek neighbors come over and listen to it.

	The positioning of speaker at the mid side is not a bad idea.

	Hi. This is my first post here. I found this place while searching for information on Mid Side Speaker arrays. I was recently ask to modify one of my MS Mid Side Matrix boards for a guitarist who had used the Centerpoint Space Station but felt it under-powered and wanted to try it with larger amps and different speaker arrangements. In the process of adapting an existing mastering width circuit I had a chance to listen to a three speaker Mid Side Array and was blown away by the huge ambient image. I was impressed enough to want to build another one for myself for casual listening. I've posted my thoughts on proaudiodesignforum.com along with schematics for the encoder: http://www.proaudiodesignforum.com/forum/php/viewtopic.php?f=6&t=742 This is the Mid Side board and Width control. Only half the board is used. The inputs are Left and Right; the outputs Mid and Side. The Width Control varies Side from 0 to 100% as Mid is varied from 100% to 0%. Four of the ICs provide balanced I/O. The heart of the MS encoder circuit are two THAT1240 and a dual op amp such as the LM49860, NE5523 or NJM2114.

	Not sure if members of this forum are aware of the following: A commercial version of a mid-side speaker system has been offered for quite some time. I bought two Space Station Mk II powered "single point stereo" speakers that were designed by Aspen Pittman when he owned and operated Groove Tubes. I use them regularly when playing small to medium sized gigs (guitar, vocals, keyboards). The 300 degree sound field from these things is amazing! Not really true stereo, however, they reproduce the stereo effects used in keyboards (like that of a Hammond Leslie cabinet) remarkably well. They provide an output for a subwoofer then when used rolls off everything below 100Hz from the internal speakers since the sub will then be handling that. The internal speakers are about 10dB down at about 60Hz. The "stereo" effect projected by these speakers is even anywhere in a room - a very interesting phenomena that is very pleasing compared to mono. Conventional stereo does not work well in for live sound PA system applications. Info on the Space Station MkII (no longer produced) can be found here: http://www.sweetwater.com/store/detail/SFXSSmkII Info. on version 3 of the Space Station (current production version) can be found here: http://www.centerpointstereo.com/about.php

	if you want to mirror a mid sid mic setup, yes. what I'm looking for is something different

	For "true MS playback" you would in theory need a dipole loudspeaker for the S signal..... electrostatics anyone??

	the encode mode sends L-R or R-L to your right speaker. the decode mode probably sends L-R to the right speaker and R-L to the left (and the other way round) but with a bit of mid mixed in i think the incline mode sends L-R to the right speaker and R-L to the left (or the other way round) Edited by hond - 18 January 2013 at 5:51pm

	yeah all well but I knew about that. I thought you said the side button gave me the unique left vs. right stereo information. what I mean: unique Left stereo = only the information that is different from the right channel unique Right stereo = only the information that is different from the left channel There's no way you can get that information out of a stereo file without some funky brain twisting algorithmic digital processing. I've broken my brains over it and it is impossible to achieve in an analog thinking kind of way if that makes sense to you

	I use MSED too. When producing I find that I can get nice surround sound effects by adding gain to the side and reducing it to the mid. It works for me. If you run in a mono signal and mute the mid, it is silent. If you bounce a track after you mute the mid, so it is only stereo, and then run the resultant track through with the sides muted, it is also silent. You can do similar things with a compressor with side chaining capabilities, but it takes some doing. Edited by b grade - 18 January 2013 at 5:19pm

	http://www.voxengo.com/product/msed/ EDIT: hm upon further investigation I don't think this program is capable of filtering out the true stereo information Edited by hond - 18 January 2013 at 5:14pm

	I did not know plugins like that existed. Looks like I've got some new material to test out :)
