Should I set up my compressor on a subgroup?


Recommended Posts

  • Members

I work at a small club on the weekends running sound. I'm still very much learning the ropes of everything so bare with me if I'm being stupid here hehe

 

The club has two 2 channel compressors. The club owner set it up so that the Kick, Bass, and two vocal channels are compressed. It seems like I would get a little more mileage out of what I'm working with if I put the compressor on a subgroup for the drums and a subgroup for the vocals. Will that work?

 

Obviously, I'd lose a little versatility in having to compress all the drums and all the vocals the same but I think the gains I would make in being able to compress everything would be worth it.

 

Thanks for the help

Jason

As noted in another thread earlier, compressing more than one instrument means you have to be okay with one loud instrument reducing the volume of everything in the group. That's pretty much unacceptable for drums. Also, does the compressor have gating set up as well? If so this scheme won't work at all, or you lose the gating.

 

It's generally the same for vocals, one loud singer reduces everyone's level. This probably isn't the desired effect, is it?

why dont u just use a soft compression thru FOH , and run the system mono.. that gives u the second compression channel to put on what u would like..

I usually find compressing, snare drums are priority than anything else live. and then bass, and kick. find which combination works best. for your second channel of compression if u try that method. bass + snare, leave the kick...Kick + bass, leave the snare???

Yes, running compression on groups makes sense for many reasons:

 

1. (the biggie for me) If your running monitors from FOH, putting the comp on a group means the monitor send is uncompressed. You'll find you can get the monitor louder that way ;)

 

2. If I'm doing multiple bands, it saves on patching between bands.

 

3.You'll find more ;)

 

As the guys have said before, as a rule only compress 'like' instruments together, otherwise things will sound odd!

 

If I were you I'd set things up thus:

 

GRPS. 1&2: Comp 1&2 over the drums (link as stereo)

Grp. 3: Bass

Grp. 4: Vocals

 

I find that using this method, I'm rarely in need of more than four comps to do a gig (rarely do I need more than 6 EVER). Gates on the other hand? Different story, needed eight on one gig before christmas! :D

I've had better luck using compression on vocal channel inserts rather than vocal group inserts. It's easier to get equal levels for harmonies. My experience with compressed vocals in the monitors is there are way less feedback problems. And you can still run them loud.

 

Not many boards have inserts on the groups but they are HANDY.

IMHO the obvious question is what kind of compressor? A cheap comp will do more harm than good in many cases.

 

When compressing groups of instruments, the loudest one will dictate the compression effect, everything else will have to follow it.

 

I rarely use subgroups except for drums, or when there is a massive number of inputs for a specific player, keys, percussion etc.

 

I'd recommend, assuming your console has channel insert points, you use them on the two channels that need dymanic taming, or group instrument types (keys or drums or vocals) and compress them.

I wonder what it sould sound like with all the compressors turned to the "off" position. Just because there are some compressor units physically present, and the other guy was using them, does not mean that they are really necessary in any particular circumstance.

 

This is really just what someone else was saying I think.

Thanks for the help guys. I'm going to do a little experimenting and see what works best in the room.

 

It is a cheap behringer compressor btw... so you're probably right about it being more harm than good if I put it on things that don't absolutely need it.
