I recently purchased an NI traktor audio 6 interface in order to allow for me to hear my monitor on traktor pro 2.
I run on a mac os (macbook pro).
I have an active sub with two passive 12" hooked up to an amp, and I want to be able to send traktors output to both my sub and my amp. They both have RCA input so thats not the problem.
In tp2 settings, it only allows me to set two channels (L and R). Is there a way I can set it to 4 channels so i can have the master output going to my sub and my amp simultaneously??
No need to have multiple outputs. You can just split the output with two RCA splitters.
The best thing is to find an active crossover and send the output to that and then send the highs and lows to their respective amps (or powered speakers if that’s what you have for mains).
The only advantage of using multiple outputs is potentially the ability to set different levels but you can likely do that at the amps with simple splitters.
Whether you use multiple outputs or split the signal, you’ll have an issue with an overlap of low frequencies being produced by your mains and your sub. In a perfect world, not a good idea as you will get comb filtering and some phase issues where the two speakers overlap. If you want the best sound, invest in a crossover.
I find that these splitters have next to no shielding, and if you touch them at all, they make nasty interference, and their just a pain in the ass. Have to be really careful when your using stuff like that.
I know exactly what a cross over does- But my sub amplifies the line out, But i’m not too sure what power it pumps out, so don’t particularly want to try incase it blows my speakers. Meh. Doesn’t matter anyway, I just connect my speakers into the main out, and the sub into the tape out. Seems to work ok.
a crossover is a filter. it doesn’t amplify except maybe 2-3 dB at the crossover frequency.
let’s assume Devils Advocato’s sub isn’t some shitty logitech squeak box. then chances are the active crossover in his active sub will have line-level outputs which carry the high-frequency band. he can then connect those outputs with line-level inputs on his amp and use the amp to drive the 12" mid-range/tops.
the small mixer suggestion, the y-cable suggestion and the soundflower suggestion aren’t good. because why would you let your tops output full range if you have a sub?
EDIT: if OP’s sub doesn’t output the high-frequency band at line-level, OP should purchase a separate crossover. they are available for all kinds of budgets.
If it’s amplified, it’s not a line out. If it says it’s a line level signal, it won’t wreck your amp - and if it’s not a POS, it will be after the crossover, so only sending mid and top to the mids and tops …
The record out is likely to be at a reduced level (the one on my Xone is -20dB) so I guess you’ll have to turn the sub up a little to compensate?
