For the past few days i’ve been having a great time learning my new Octatrack Mk2, but i’d been using the headphone output since I didn’t have spare cables for the main outs.
When I hooked up the main outputs i’m only getting sound in the left channel. If I partially remove the left channel I get a signal in both cables but its mono (I have some crazy panning stuff in the track so it was obvious comparing it to the headphone output). I tried this in demo mode as well and I get the same issue.
I’ve tried multiple cables as well, so the problem definitely lies with the Octatrack or me doing something wrong on it.
Is there anything i’m missing here? Or should I return this unit - I bought it through Amazon so I have a couple more weeks in my return window.
I tried some brand new Hosa 1/4" cables I bought, then also tested some guitar cables I know work and have been tested on other gear. I had a stereo pair going from a synth to my interface that I also know are working so I tried those - same issues.
The cables are going from the main outputs on the Octatrack to inputs 1 and 2 on my audio interface - I did this same setup when I was going from the headphone output except in that case instead of straight mono 1/4"to1/4" it was 1/8" to dual mono 1/4". It worked with the headphone output but I also had ran my OP-1 through it as well and it worked fine (and the synth I mentioned before). Monitoring is just done in Ableton Live.
So I know the interface is receiving fine and should be sending audio just fine since it was tested multiple ways, and I know the cables are fine because I used known good cables and also confirmed that with known good gear.
…one stereo jack for the headphone out…mono jacks for the main outputs…
one for each side…left AND right…
u know…
if the jack has two black rings…it’s a stereo cable…perferctly suitable for u headphone out…
if there’s just one…guess what it is…
no worries…u’r getting there…
@reeloy I think you’ve misunderstood what I mean. The main outputs should be a mono left channel and mono right channel, but instead when both are plugged in the right channel has no sound (unless its plugged in half way, then it duplicates the left channel and I have two left channels).
I’ve been racking my brains over this and it just doesn’t make sense to me, that from all of the things you’ve described, that you would get those issues.
One thing that you haven’t mentioned is what is playing on the OT? Could it be an issue with inputs AB/CD and DIR settings or THRU machine settings?
I would definitely put in a support ticket. Hopefully they can fix you up before the window closes.
Pretty unusual problem. Sometimes I have gotten some weird side effects from being in Cue mode. But yeah I’m stumped. Could be a bad solder joint or a grounding issue with the jack.
@Veets I purchased it through Amazon and support was able to have them ship me a replacement arriving next week, and I just have to ship back the current unit within 30 days which is a pretty awesome policy for music gear. Means I can keep playing with it until the new one arrives and then ship the broken one out haha.
I’d imagine the re-seller would end up shipping back to Elektron and then they would re-sell it as refurbished or something.
@GeneraStudios so it works properly with your headphones output?
You can check MAIN L and R outputs with heaphones btw. What it says?
Normally you can hear each channel distinctly L or R on one side of headphones.
I’d check with a regular mixer. From what I read here, most of outputs problems were due to soundcards inputs.
@sezare56 Yeah it works with the headphone outputs, but i’m not actually plugging headphones into them. I’m plugging the headphone output to a stereo to dual mono cable into the same interface i’m using to test the main outputs (the same inputs of the interface, so I know its not the interface causing the issue).
I did test the main outputs 1 at a time though. If I plug in the left output I hear the left channel, if I plug into the right output I get the left channel, and if I plug in both I get nothing out of the right output and only hear the left output of the left channel. If I start with the right plugged in i’ll hear sound (from the left channel), then if I plug in the left output the right output goes away entirely leaving only the left channel audible.
Its almost like the two outputs are coupled together in some weird way.
My old interface would do this if I listened to the signal directly at the interface (direct no latency monitoring) - no stereo signal - I had to listen to the signal after it passed through my DAW to hear it in stereo. @GeneraStudios did you test the op-1 on the interface and it worked fine?
@sezare56 I have plenty of headphones, the issue is I don’t currently have an adapter to split the stereo plug of the headphones into two mono ports to go into the main outputs.
I’m going to try and see if I can rig something up to double check, I just find it very unlikely that the problem could be the interface considering i’m able to monitor several other devices fine with it in the same setup with the same cables and it works fine with the headphone output of the OT.
I actually was thinking about this last night and did a test for you. If I plug headphones into a main out, I can reproduce your situation. Plugging headphones into the main out will make a (loud!) signal go on one side, and pulling it half out makes that signal go to both sides.
