I don't have any real experience with dsp/system control units other than occasional use of the low end driveracks.
Here is the specific problem: I would like to get even coverage in a long rectangular room at maximum 90-100 db over the listening area. This is for acoustic music so I don't want to have to blast the front rows to get the sound levels in the rear of the room.
It seems to me that this could be accomplished by adding delayed fills for the rear of the room using my HPR 152's on stands. The question comes up for how to provide the delay.
In my searching, I did not any dedicated delay units that I thought were price effective especially if you are going to set up more than one zone. In looking at the system control/dsp units, I think that a 4 input/8 output unit would fit my needs perfectly, and the price on the units I was looking at was definitely less than trying to get crossovers/peq/delay for 8 channels.
I looked at the specs for dbx, sabine, ashly, among others. I think the Ashly Protea 4.24C fits these needs extremely well.
I would be interested in hearing comments about this specific application (either running zone delay for powered speakers or specifically the ashly unit or other comparable units).
Thanks
Jay
P.S. Other than Sam Ash online, my searching did not turn up any ashly dealers I recognize the name of. If anyone knows an ashley dealer I might talk too, let me know (If you are a ashly dealer I wouldn't mind a pm)
