Members MoonMix Posted October 4, 2011 Members Share Posted October 4, 2011 hello... was at a live gig where I didn't have my compressor (dbx 1046)...& needed a little something extra on the vocals. so...I assigned all vocal channels...(which were already assigned to my mains)...to Sub 1 & 2...simultaneously... ...& then pushed the Sub faders up a little bit...& got what I needed. I know this is probably dangerous, from the standpoint that in doing so, I've eliminated true metering; & as such could be clipping the input to the mains... but what actually happens here...???...it's cumulative gain, correct...??? thanx, MoonMixMackie ONYX 1640i Link to comment Share on other sites More sharing options...
Members scarecrowbob Posted October 4, 2011 Members Share Posted October 4, 2011 You could get the same thing happening by turning up the channel volume-- that's all you should be getting from that, unless you are starting to clip. Link to comment Share on other sites More sharing options...
Members Shaster Posted October 4, 2011 Members Share Posted October 4, 2011 On combat audio gigs, if I've got sub groups and "have" to use a post fader send for monitors I will use a subgroup for the inevitable volume creep - and I use it usually on lead vocals. So I set a pretty good vocal level and monitor level, and double assign the vocal to mains and a subgroup. When the volume starts to creep I can't turn up the individual channel because the monitor could feed, so I use the subgroup to tailor the lead voc volume. As I said, that's a combat audio situation. I'm not worried about overdriving any internal routing. All I'm worried about is feedback - which is the one thing anyone can hear. Guess you could do the same thing with an extra channel but on the gigs I'm talking about, channels are in short supply but subgroups are plentiful (Mackies and Mackie clones).

Members Phil Clark Posted October 4, 2011 Members Share Posted October 4, 2011 If you are running monitors and mains from the same board, then that is a safe way to get more gain without changing the monitors. If you were NOT running monitors from the same board, you would get the same effect by just bringing up the gain on the channels you needed. I had to read your post twice though, because the first time I thought you were putting vocals in the subs, not into a second sub group on the board. And my first thought was... "NEVER DO THAT". Anywho... carry on. Link to comment Share on other sites More sharing options...
Members abzurd Posted October 4, 2011 Members Share Posted October 4, 2011 You've stumbled onto a version of "double bussing". I do this with the snare in my band as I'd have to run the board lower overall to get that same pop from the snare otherwise. I also double buss the lead vocals, but not with a sub-group. I run them in stereo thereby using 2 channels. It allows me to run the lead vocal channel lower than I would otherwise but get more out of them. It also works well for a few screwy effects I'll use during the night like a ping-pong delay. Link to comment Share on other sites More sharing options...
Members KF650SB1000 Posted October 4, 2011 Members Share Posted October 4, 2011 Double bussing the vocals (or anything) is the same as pushing the slider up. The output sends doesn't mater if you turn the channel up 2-3 clicks or push the Buss sliders up. Don't confuse DCA with Buss/Sub-Groups. Link to comment Share on other sites More sharing options...
