route MAIN to SUB1

Postby DFreeze » Sun May 13, 2007 8:57 pm

Hi all,

I've got a simple question I couldn't find the answer to. I use my sampler mostly for live gigs and I'd like to duplicate the main output to the submix1 (or any) output. This is because I have my own amp on stage and main has to go to the mix, and both just have to sound the same...

How do I set it up?

I'm not sure you can assign a single voice to multiple outputs. It either goes to the main outputs or the sub outputs, not both. Your best bet might be to use a "splitter" cable and physically send the signal to both destinations.

You can assign multiple outputs for a voice in the voice amplifier section
(first page) in preset edit (Main send, Aux send1...)
But the effects stay on Main Outputs I beleive

Fiddling with the preset edit screen, I can't see any way to send a voice to more than one output set at a time. The voice amplifier section mentioned in the previous post only lets you choose ONE of the options (Main, Sub 1, Sub 2, Sub 3) in the Submix setting.

So, unless you're going to assign a second, identical set of voices to the sub 1 out as well as the Main, I can't think of a way to do it... just using a splitter cord would be much simpler.

[later]
OK, there might be a way to do it, but only if you're NOT using the effects buses for anything important. Basically, you send the voice to a sub out, then set the effects send for that sub to 100% (all wet signal). The dry version of the sub out will appear at (surprise) the sub out. If you set the effects to their absolute minimum settings (not bypass... ok, it might work in bypass, but I'm not testing this out) so that 100% wet is actually still pretty dry, you should get pretty much the same signal from both the main out and the sub out.

If you really want to use the effects for important things... well, you'll just have to put up with your monitor mix being 100% dry (which, depending on the effects, could furk up your timing a bit).

Yeah, I've thought of the minimal-effects route as well, but as you say, it limits the use of the sampler when effects are wanted. I'll look into the splitter-cable as well, but I'm wondering if input-impedance stuff won't mess up the signal levels. But I'm just guessing here, so there may be no problem here at all.

Hmm... it's just occured to me that there might be a problem with using the splitter cable approach. The outputs on the E4s are balanced, which means that if you use a stereo y-splitter (a regular stereo to dual mono cable, it's effectively splitting off the tip signal to one branch of the cord and the ring to the other, so that a stereo signal could be split into discrete left and right signals) then the signals will be 180 degrees out of phase, which could might produce some phase cancellation issues between the house feed and your monitor-amp feed. I'm not saying you WILL have a problem, as it will probably depend on the distances between the speakers involved... and the house feed would no longer be a balanced connection (might not be an issue, or might be noisy as hell). You'd need a cable that absolutely duplicates the pair of signals at a balanced plug on each branch of the cable... well, two of them, actually, for the main-L and main-R jacks.

I'm not a sound engineer or tech or anything, so I'm not sure if I'm even on the right track with this (haven't got a cable wiring diagram lying around or anything, gave up electrical engineering in college to wander the universe... long story, don't ask...)... any more technically skilled people out there want to buzz in on this one?

Halve your polyphony.

Copy your voices to a new group then assign each group to different outputs - sort of thing.

You are talking about an insert cable that breaks the ring and the tip on a stereo plug out to to individual tips on mono plugs. I was talking about a cable that just takes the tip of a mono plug and routes it to the tips of two separate mono plugs. This would be using the outputs in unbalanced mode and would send the signal to two destinations at once. It should not effect the quality of the signal in the slightest particularly if you are using DI boxes for both outputs.

Ah... much clearer.

Well, it was just a thought of a potential problem that crossed my mind. Wanted to mention it just in case.
