I never thanked you for this, but thank you now as this completely set me straight in regards to what i wanted to do, i have run into some problems however and i have some questions about how to solve these.BertKoor wrote:I'm thinking you might need a slightly bigger DJ desk that features some extra inputs. There are also audio interfaces with 8 (mono) channels that double as a mixer when not connected to a computer.
I had a close look at the block diagram of the Behringer 2442fx. In principle this has the same topology as a Mackie 1604: Insert is right after the Trim and before the EQ, Direct Out is right after the fader.
But looks of the back of the 2442fx deceive. It doesn't have 8 subgroup outs. Well it does, but 5=1, 6=2, 7=3 and 8=4. Yes, 5-8 are the very same, hard-wired to 1-4. Manual page 15 states that in order to record 8 tracks you have to do that in two passes. First record the odd tracks, rewind and record the even tracks. Sounds very silly...
On a channel you pan it left and/or right.
If it's panned left and you select Main, it goes to Main Left.
If it's panned right and you select Main, it goes to Main Right.
If it's panned in the middle and you select Main, it goes to both Main Left and Right
If it's panned left and you select Sub 1-2, it goes to subgroup 1 (and 5)
If it's panned right and you select Sub 1-2, it goes to subgroup 2 (and 6)
If it's panned in the middle and you select Sub 1-2, it goes to both sub 1 and 2 (and 5-6)
If it's panned left and you select Sub 3-4, it goes to subgroup 3 (and 7)
If it's panned right and you select Sub 3-4, it goes to subgroup 4 (and 8 )
If it's panned in the middle and you select Sub 3-4, it goes to both sub 3 and 4 (and 7-8)
Each subgroup receives the sum of everything you have assigned to it.
On the far right there are faders for each of your 4 subgroups.
Just above there's buttons to assign that subgroup to Main Left and/or Main Right.
So if you assign:
sub 1 --> L
sub 2 --> R
sub 3 --> L
sub 4 --> R
then you get effectively two stereo buses with faders to control the volume of that group.
By assigning a group to both Left and Right, it has become a mono group.
What I use groups for (when mixing a live band) is:
* Assign vocals directly to Main
* Assign instruments (bass, guitar, keyboards) to Sub 1-2
* Assign every track of the drum kit to Sub 3-4
So if I want to adjust the volume of the whole drum kit, I can do that with the subgroup 3-4 faders and leave all the 8 individual track faders of the drum kit alone.
For your application you don't need that. You have two stereo sources and two mics: 6 tracks. No need to "mix" then prior to recording. Honestly, a mixer for this sounds a bit overkill to me.
It seems that even if i am panned towards the left with the subgroup 1/2 button pressed down, which should select subgroups 1 and 5, i am still hearing the same sound through subgroup outputs 2 and 6(though slightly fainter).
The only way to isolate subgroup 1 from 2 is to turn the volume down on subgroup 2.
I am not sure what if anything i may be doing wrong here...
To give you a bigger picture of what i am trying to accomplish here, each subgroup output(1,2,3,4) is connected to a different amplifier controlling a different ring of speakers which are in separate rooms, through the subgroup select options different channels need to be routed into a different amp through a subgroup output, because of the "bleeding" which is apparent between different subgroup channels, noises which we just want in one room cna be heard in others.
There is a control room for subgroup 1, a dj roomfor subgroup 2, a vocal booth for subgroup 3 and a lounge area for subgroup 4.
Any help here would be apprieciated and if i have been unclear about anything please let me know...
