speaker tunings now found in the pa+

Robobear19

does anyone know where i can find the speaker and amp tunings for the driverack pa+ specifically for the yorkville e15', yorkvilles 608's (more specifically the ucs1), and qsc 3602's. I have the old driverack pa without the usb port for upgrading firmware and would rather find the tunings online and manully input the tunings into my old pa rather than buying the new one.

There is no update for the DRPA+ and there isn't likely to be one for some time (new product and all) ...

That said you really don't need one unless you are bi-amping the tops... are you? If not then a simple HPF/LPF for the sub and a LPF for the tops and be well on your way....do you have the mic? If your going to bi-amp the tops there is a pretty good helper in the processor manual... a crossover plot...otherwise yorkville is useless when information about their products is concerned...especially where tunings are concerned...

The actual settings depend on application and system components...
amps/speakers...how many... bi-amp?

I have the E12. They use the save processor and therefore the same tweeks are used. Yorkville used a little magic in way they built the system. There is no damping material in the cab to cut down resonances, which make the box very efficient. The processor fixes the issues caused by the cabinet design. I will try to copy my settings (guestimated using the chart in the processor manual and tweeked with the RTA mic) and post them back.

Knew I had is somewhere...
I have SW800 subs (808) so your 608's should work with the info below.

Full range set-up E12 only (Passive).

X-over: HPF
56 hz BW18 (E15's can change to 45hz if needed. I would not go below 50hz.)

PEQ: Hz Db Q
F1 75 +7 1.22
F2 315 -7 9.55
F3 800 -5 9.55
F4 DRPA settings, never went to the trouble to redo for 260.

2 Way Set-up E12 (Passive + sub)

X-over: Low
47.5 hz BW 24
100 hz LR 24

X-over: High
100 hz LR 24
OUT (This again, is the my DRPA setting and would probably LFP at 18K Hz BW 6 (or 12).)

PEQ High: Hz Db Q
F1 125 +5 1.22
F2 315 -7 9.55
F3 800 -5 9.55
F4 Same as above

PEQ Low: Hz Db Q (Yorkville)
F1 47.5 +4 2.03
F2 60 +2 5.71
F3 Same as above
F4 Same as above

thanks alot gentleman..


and just to answer some generic question i use 2 plx 3402s to be exact......
i power 2 e15 tops and 2 ucs1 bottoms(both from yorkville)......1 speaker per channel...I run a simple 2 way system 1 amp for bottoms (low output) and 1 amp for tops (hi output)...and thats about it. the 3402 is powerful enough to run 4 tops....2 per side,,,,when i have larger audience i run an extra two tops

Isn't that like saying..."I drive a Volkswagon (more specifically a Lexus)"?

hahahah yes yes i know i make those posts when im dead beat but my exact speaker is the yorkvilel ucs1 ......but some have said i can use the settings form the 608's as a gude for the ucs 1..dont know how true that is...

Dra really? I wish I would have known about this idea earlier (couldn't have) because two weeks ago I insulated my JBL tops which had absolutely nothing in them. I'm sure JBL did it out of saving costs -- but Yorkville does that? Are we talking about their subs? Tops?

After I stuffed my tops and re-ran the flattening session -- very little change on the Parametric settings. My alignment times changed a little.

Dra

Subs usually don't have fill, unless it is to "increase" the volume by design. The dampening in top cabs also tame standing waves in the cab. Generally speaking if it has it or not, it is for a reason.

The UCS1's are listed in the processor chart, so the tunings should work well. (or not)

No fill in Yorkville subs OR any Subs? I'm pretty sure my JBL tops were not insulated because JBL was lazy. They are the old TR 126 Series that they made for I think one year. After that -- they never made them again. This was my thinking about why I insulated them: I knew what my parametric settings and alignment time were in the tops UN-insulated SO what I wanted to see was IF the alignment time got longer or shorter and also did I have to use MORE or LESS parametrics to even out the response. I would think that less delay and less parametric would suggest the better way to go. In my case -- the parametrics stayed about the same BUT the alignment delay was shorter. Not much though. Anyone know of a Hierarchy in sound? For example: Less EQ is best, less delay is best. Less delay on a horn that is polarity inverted is better than a horn In polarity with a crazy delay time...etc.

I would think dampening material would do just that -- dampen the sound as well as dB. I wouldn't think insulating would make the cab louder. BUT -- I could be very wrong.

Dra

Volume as in size, not loudness. Sorry for the confusion. :?

Dr. J

So your Yorkville's are empty.....No insulation?


I wonder about G's LabSubs? Any Subs????? Shoot -- I stuffed my Fanes full of it.

To Stuff OR Not To Stuff?

In a speaker ...adding batting lowers the Q of the box...It also can help reflected energy inside of a cabinet that would lower the distortion factor... It isn't usually necessary in subs where the frequency reproduction is not high enough (frequency wise) to be affected by such reflected energy( the cones move too much to be bothered by reflected energy...) ... however in a top, it wouldn't necessarily make it any louder, OR lower the resonant frequency of it when crossed out of the low frequencies as in your subs tops config... I suspect if the tops were capable of 50hz @3db down batting might smooth out and lower the boxes qts effectively allowing it to reproduce a little lower frequencies, but as I said all the frequencies those cabs would reproduce wouldn't be affected by the batting.. only the THD...

So I'm not surprised you are not seeing a major difference in the SMAART plots...but if you were doing distortion measurements I would expect to see a difference there...

I actually tried batting in the back chambers of the Labs and I ended up pulling it out... I do however put some of that acoustic tile (the matted fiberglass ceiling tiles... I pull the facing off and glue it with 3M 77 ) on the inside of the fane boxes to damp cabinet resonances further.
