Essentially, when running a signal from Logic into my Mackie mixer or s2400, the signal is slightly aligned to the left stereo field rather than central as you’d expect - see lower stereo image on attached pic.
I’ve had this issue for months and have been running tests but can’t seem to figure it out so asking here in the hope that someone with more experience might recognise it.
Could you describe your signal chain with a bit more detail? Sounds like you’re saying whether you connect to the Mackie or S2400 you get the stereo skew. If that’s the case I’m thinking you can narrow down the problem to something other your source (Scarlett interface?)
Also what difference are we talking about between channels? 1-2dB might be expected depending on the quality of your interface outputs, but more would indicate something’s off.
Try connecting the Inputs on the S2400 to a direct output path. You have to narrow down the path to see what’s causing the problem. If you can connect a different sound source like another drum machine or keyboard output dirctly to the 2400’s inputs and it sounds aligned then you know it’s not the 2400. Kind of like a process of elimination to figure out the source of the problem in your signal chain. Also some records were mastered a little off. If you’re sampling an .mp3 or vinyl record then try using a different record. Try using a different pair of cables as well. I doubt it’s your 2400. If you’re using a mackie analog mixer in your signal chain the faders need to be exactly at the 0db in perfect alignment. Also make sure there isn’t a different EQ setting on one of your stereo channels and they’re panned correctly. The left pan knob needs to be fully hard left and the right pan knob fully hard right. Make sure your audio interface doesn’t have different output levels. The stereo outs need to be both at the 0db setting. I’m sure it’s something very simple. Also make sure the 2400 inputs are set to the same lefels and one is not boosted up by an internal setting. Like I said… it’s always the simplest thing that we overlook. Good luck. I know you will figure it out. Hang in there
The skew is about 1 -2 db. Not loads but enough to cause issues with my mix when using breaks.
I did these tests with a mono break:
Logic > Mackie > Logic = skews signal (see image below)
Logic > S2400 > Logic = almost normal signal (not perfect mono but close enough)
So its to do with the Mackie or cables, I guess. Would it be to do with balanced / unbalanced cables? I’ve got £10 cables from Amazon so maybe I need better ones? I watched a video and I’m still trying to get my head around all that balanced / unbalanced stuff.
Hi bro, sorry to here about your issue. I mostly use balanced in my entire studio. These cables are also grounded and less likely to pick up electronic hum from other gear and cables. Also, the makie CFX mixer has a pan knob I assume on each channel. Try slightly turning it to see if your mono signal can be more centered on your graph. My last idea to try is the outputs from the S2400’s outputs. Maybe try to output your break samples in only the Left output of the S2400 to the Mackie… see where the signal shows up on your graph. Then try the Right output into Mackie and see where that lines up on your graph. I don’t remember if there’s a menu on the S2400 to set the db level. If there is try adjusting that. It may also be a slight pan issue on that one channel of your Mackie… you can try a different input on the Mackie to see if things line up better. Try with your pan knob in dead center. If on the other channel your graph looks the same as your other then I’m not sure what else to try just yet. Out of curiosty, have you tried using a different instrument going into the Mackie’s input to see where the graphh lines up? Maybe try that. If a different instrument is dead center on the graph using a mono cable then you know the problem is coming from the S2400’s output. Keep in mimd that even a mono sample can be slightly off when it’s originally sampled. Even the source material like a record has panning involved during the mixing session after the band records. Alot to take into consideration. Once again, good luck my brother.
Did you ever get this figured out? I am having a similar issue. I never really used the analog outputs until I got the DSP card. DSP audio works as expected but my mix output via the analog outputs are shifted to the left a fair amount.
I’m running it directly into my MOTU 16A. It’s almost as if there’s a filter on the right side.
