Quick connectivity question

twkd2

I just got a Driverack PA and I'm a little confused about the stereo outs. I'm the engineer for a church and our current configuration is a single sub cabinet (2 18\" Yamaha) and 3 Worx Audio 12Ai's in a center cluster.

It's currently crossed over @ 120HZ. Would I just use one of the stereo outputs to feed my amp for the Worx cabinets?

BTW, we have a Yamaha 01V96 board and 2 Yamaha P7000 Amps.

Our current processing chain consists of an Alesis MEQ 230, Alesis 3630 compressor and Behringer crossover.

I'm hoping to eliminate all 3 of the afore mentioned components with the Drive Rack. I wanted a 260 but couldn't afford it on the budget we have.

Thanks in advance for anyones help.

Regards,

David

The problem is you didn't list the amp/amps you have that would determine what my/our recommendation would be...Yes I would eliminate all the aforementioned components...If you have only one amp to run the sub AND the cluster then yes.. only one channel, but if not..well give ALL the info first... then we'll give you options...

Gadget, He did. :oops: :oops: 2 yamaha 7000's.

David, how are you currently connecting from the amps?

1 channel for Sub
3 channels for cluster - signal is split with y cables.

Keep in mind I only have a snake with 4 sends on it and am using 2 for and external feed.

Thanks for any input!

Ya so I'm blind at 2 in the morning...

I'd set up a 2x5 use the left channel for the sub on the left mono sub out, I'd then run the ctr cluster off the three right channels one for each speaker. This way you can power shade the room. You could set it up as a L/R C setup also using 2 of the right outputs.... and the left for the sub.

Then you set up the 3/2 right outputs as partial bandpass filters by dragging the HPF to where you want it... say 100 hz LR24...then set the sub up 45hz BW18 and use the LR24 @ 100 hz LPF.

Then you can run Aux fed subs if you wish also.

The only issue I have is I only have 2 sends on the snake to feed the power amps. Essentially I need to either locate the DBX unit with my power amps (not really desireable) or just use a low and high frequency send.

If this is case what are your recommendations for setting it up?

Thanks!

Remote the PX and do it right...

I don't like the idea of my house EQ being 100' away from my fingertips if you get my drift.

So let's assume that I don't remote it, what config would I need to get it to send one low and one high through the snake to the amps?

Thanks!

Is reversing (either by make M-M & F-F cables or actually changing the end connectors) a few sends an option?

I'm maxxed out on my snake.

Is there some big advantage to running my cluster speakers independently that I'm not aware of?

I've never desired to have individual control over the cabinets in the cluster. They've always been a single unit. I'm just feeing them 3 channels of power because I didn't want to run my power amp down to roughly 2 ohms.

I guess I'm looking for a 2 way setup so I can have control back at my house board.

Thanks again guys!

The advantage of individual control is help eliminate \"hot spots\". For example, if the center cab is in charge of the getting to the back of the room while the R&L are in charge of the ... well, L&R , but most as it applies to the front, then the center channel needs to have more output. But then again, you can control that by turn down the L&R amp attenuators. I am making some assumptions about the room and how the cab are \"aimed\", so take with a grain of salt. By running separate outputs (center & R/L) from the DRPA you would gain the ability to have a separate GEQ for outputs. This is done by setting up a dual mono GEQ and 2 x 5 (all input from the board must be panned to center, or mono). Hi output (L) is center, mid output (R) is L/R, sub uses the mono L output. Then set up the x-over as... Hi 100hz and up, Mid 100hz and up and sub 100hz and down. The left GEQ controls center (and sub) the right GEQ controls L/R (and sub). This option gives you the most control of the sound field.

To control all 3 cabs and sub using the 2 available lines... set up a stereo GEQ (single control for both sides) and a 2 x 3 x-over. Mono mix line from board to Left DRPA input. Use Hi (L) and mono sub (L) outputs.

PS - If you would like to bridge an amp for the subs to get more power then there is an option to allow \"power shading\" for the L/R speakers (increased power to the center if you need it) using the one remaining amp. A concept \"developed\" by a Peavey guru, or at least explained.
