Driverack settings
Hi,
I am currently using a DRPA in a DJ system with 2 Yorkville E2152s as mains and 2 Cerwin Vega EL-36 as subs. I just wanted to know what the optimal configuration would be for these speakers and this setup (crossover, delay, etc.). Also, how would I set the limiter on this system. It is used for music playback, as well as for some speeches, etc. Thanks a lot!

Yorkville 2204 Elite's over LABsubs. I think the hornpath would be about 8 feet versus my 10, but similar none the less. So I suggest a BW18@ (depending how much power you have) @ 35-45hz HPF. A 90 hz L/R 24 LPF.
As for the tops, 90 hz HPF@ L/R24 to out. Delay the tops 15.5-17.5 ms.
This should get you close.
Until we actually get the \"tutorials brought over from the other forum, you'll need to go there for your required reading:

Here is an excerp from the that section:
The limiter would be better for your purpose, judging from what you said. Just select the limiter, under the dynamics button menu. the best way I can say to set it is to select how hard you want it to limit (limit means to stop from doing..so we want to stop the sound from exceeding a pre specified point) That point is the 'threshold'. How much we allow the sound to overshoot is the 'Knee'. '0' being the least '10' the most. So, if we select a 'knee' of 5 and toggle the limiter 'on', then start dropping the threshold (remember that we have '0' db/vu and the numbers go up to +20, and down to -30 or whatever... This means that if we get the system as loud as we want @ '0' db/vu, then we should try and get the limiter to start 'hitting' the limit @ around '0' db/vu. So start dropping the threshold till you start to see the +/- bar graph @ the top start to flash...the longer the line the harder limiter is hitting... now, as you change the 'knee' (set the knee to 8 now) you will start to audably hear the limit. So as we lower the 'threshold' we start to get limiting, as we raise the 'knee' we get more stopping power and in a shorter distance...
Good luck and get back so we know how its going

Thanks a lot for the help! The only question I have is about the specs for the crossover settings.
\"I suggest a BW18@ (depending how much power you have) @ 35-45hz HPF. A 90 hz L/R 24 LPF\"
\"As for the tops, 90 hz HPF@ L/R24 to out. Delay the tops 15.5-17.5 ms.\"
How would I got about setting the two different hz values on the driverack?
Also I couldn't figure out how to set the delay to 15.5-17.5ms ..... it stopped at 10.
Thanks Again.
As for the other you need to set the unit on a table and start toggleing through till you can easliy navigate the unit... then, press the XOVER button and select the parameters I specified ...its that simple. I can't take you button press by button press.

I was wondering if I could set the delay for the E2152's as 8ft. Would this be correct?
Thanks Again!

I have not found a definitive horn length for the EL-36's but as near as I can figure with a long axis dimention of 36\" that X 2 for the bottom and back sides and 2/3 that roughly to the center of the woofer thats 8 feet...That means roughly 7 ms, BUT, the L/R 24 delays the sound of the bass by an additional 7.5 ms (8 1/2 feet), which puts the correct delay setting well out of the DRPA's capabilities. You could set the delay @ 10ms and back the tops up to the back of the EL36's and get closer...but you'd still be over 2 feet short...
These are only subtle differences and I guess I would set the system up and play it loud and run through the delay possibilities and see where it sounds best. That is how I arrived @ 17.5 ms for my rig before I ever knew about the 7.5ms delay of the L/R 24 filter...I wondered why I had ended up there, but I knew it was right... thats pretty much how I do all my basic setup, I've been doing this so long I can identify sonically whats right whether its phase, delay equalization... or whatever...

You sure know your stuff! Thanks again for the help; my system's sounding better and better!
