I DJ'ed an outdoor college spring fling dance today (450 students) and I am now so sold on this Bose system that I can't put it into words!
4 towers and 8 subs is simply a wall of sound.
I went out 400 feet and this system was still still rockin the house!
I was at 80 % volume and was hitting 117db's.

Heres another

and another

U rock, Mike! Tell us more. I've never been out 400 feet at a live event, so I'd like to know what it sounded like out there. Also, how far away were people dancing? Were you in stereo? How wide was the audience? Any problems? Echoes off the buildings? You've really pushed the system to a new place and I think a lot of folks would like to know what you found. Please share.

(Edited to remove questions answered by replacement photos.)

All these pictures were shot one hour before the event start time.
They danced right in front but I was playing for the whole area also.
At 400 feet it was wedding reception volume
At 200 feet it was ACDC volume
At the stage I was looking for Robert Plant to show up!
I was looking for the top but never even came close.
I was running in stereo and only had a 16' stage.
The area was 600 feet wide and I had awesome sound everywhere.
Not once did I hit red.
I thought if a band can jam with 4 of these units then why not a DJ?
Mike

Heres a full view at setup

that's a lotta dang speakers!!!

wow.
Is this all your stuff?

My band still thinks two systems is a lot of gear.

Wow! 117db?? That's loud! How was the bass throughout the area?

I'm looking for a good "desk" as well... is that an SKB case you have as your console? Which model is that? Thanks!

That is the SKB mini gig rig setting on a SKB roller amp rig.
Yes this is all my equipment.
I just had custom stage risers made for my Bose system so my next event like this I will be able to put a 15' gap between the left and right towers.
The bass was awesome in the whole area.
My settings are preset 00, low on remote @ 3 o'clock,master 12 o'clock,OL 2 o'clock and the rest @ 12 o'clock and my mixer runs flat with IMP pad's-20's installed at mixer.
My PS1's have the trim settings at 8,,,,I have perfect gain and without that this system will not perform as intended at these higher levels.

How did you connect the 4 PAS to a stereo source? Do the 2 main L-R PAS feed the other 2 PAS? Or does each PAS get a feed from the mixer? (main outs and sub outs)

I use an XLR Y spliter pre first PS1's then run a 5' XLR cable to the second units on each side.
All four towers get the same line level.
Mike

So, no stereo? Combined signal (Mono) to each PAS.

no, no... mike was running stereo. he had 4 PAS.. that's why I asked how he ran the signal to all 4. Each pair of PAS was connected via Y-connector

How were you juiced? I see one ext. cord taped down and running off ofstage right. Was everything off of a single 120V/20A?

I used two seperate outlets.
The XLR Y was used on each side at the end of my XLR cable but just before the first PS1 unit.

Mike,

Awesome setup my friend! What mixer are you using? I am shocked you can run the the trims that high..unless you have your mixer set at mic output.

I have been running my trims at zero.

PAT

I use a Rane MM8z Mojo mixer and I use two IMP-20 pads (left and right Channel) to pad down the signal.
This allows me to set perfect gain and with my system thats puts the trim setting at 8.
I have not seen red since and the sky seems to be the limit now (lots of headroom)

Cool pics!

A comment & a question:

You could eliminate the "Y" by just taking the Line-out from the "inner" systems to the "outer" system (use the 5' cable you have in place now, just eliminate the Y). The only drawback is that the Trim on those "outer" systems would be different that on the "inner" systems to give the same volume.

Question: Did you get much in the way of phase cancellation out in the listening area? You are overlapping the sound field with two identically-driven towers. Outdoors, it might not be as much of an issue as it can be indoors (where reflections can make those "phase cancellations" worse).

One suggestion, when the location warrents it, might be to angle each pair of towers (on the same side) at ~45 degrees off center (in opposite directions, of course): That ought to both reduce the potential phase cancellation AND give you a wider field of coverage (e.g.: 260, rather than the nominal 170).

I use the Y's to have the exact same line level to each unit.
If I did it your way then there is a 4db kick to the next unit and I don't want that.
These PAS units don't suffer the phase cancellations like conventional speakers do.
I had confirmed this with 4 different Bose techs.
They all said to have at least a 4 foot gap between them.
I have heard nothing but great sound in this configuration.

There has been a lot of talk lately about phase cancelation, etc. Like the demo at Guitar Center in Mayfield/Cleveland was most surely do to this issue. How did Mike get away with it?
