Live sound guys Urgent help please!

[pikachu69]

I am building a PA for a touring band I will be doing FOH for the national league of their tour. It is a large band and they require 7 seperate monitor sends, which is fine, but that only leaves me with 3 more sends (32 - 10 snake) to get from the mix position to the speakers. I usually run a DBX drive rack 260 in my FOH rack so I have the control from the mix position but I require 4 sends, stereo highs and lows.

My question: what if I went stereo highs and mono sub?

I have never run subs in mono live before and I want to make sure it will not kill the bottom end as it is a regaae band that requires a generous amount of bottom end. I will be running 8 JBL PRX618S-XLF subs.

Any thoughts, experiences etc.
Discuss?

Cheers.

Use gender converters to convert one of the 32 channels to a send instead.

 

[pikachu69]

All channels in perminant use...

When it comes to live sound I prefer to run everything mono so I get the same mix everywhere in the room, unless there are specific stereo effects needed, but then typically only a percentage of the audience will properly hear it anyway. About running subs mono, I don't see any drawback doing that since all that low end junk is pretty much unidirectional.

Mono subs are fine. You can also convert the serial cable for the DBX into XLR (it doesn't use all of the serial pins). Then you could send stereo to the stage and run the 260 from there but remote control it via laptop.

Simply cut the DB9 cable (this is not a null modem cable) and put pin 2 to XLR pin 2 pin 3 to XLR pin 3 and pin 5 to ground pin 1... thats all thats necessary! Remember to not have your serial ports doing anything else or you will not be able to connect.

Mono subs are fine, Stereo mids & tops with mono subs is how I run my system

I always run subs in mono. Not a big deal man, you'll be fine.

Great thank you guys so very much.
I didn't think it would be a drama but since I have never done it I just wanted to ask to be sure.
As always you guys are legends!!

Cheers.

Stereo subs are largely unneccessary as bass frequencies tend to be omnidirectional.

 

[Sloan]

omnidirectional.

ah, shit i just realized i said unidirectional. LOL.
