The Left channel of headphone out has a higher perceived level than the Right channel at very low volume when playing back mono audio samples.
Steps to reproduce
Turn the power on the S2400
Load any kit or sample (mono)
Plug-in headphones into the headphone out
Turn the Phones knob on the S2400 to the comfortable listening level (2 o’clock in my case)
Play back the sample
Turn the Phones knob to the minimum value
Start increasing the volume using the Phones knob until the audio is audible
Observe how the perceived audio level is higher in the left channel
Continue to increase the level until the comfortable listening level while repeatedly playing back the sample
The perceived signal level becomes more even as the Phones knob is turned clockwise
Observations/Assumptions
It could be that the signal level remains uneven between L/R channels with the Phones knob turned to the comfortable listening level. The assumption here is that it might be more difficult for the human ear to register the differences in level between L and R channels at higher volume. Due to that perceived audio level is mentioned instead.
The issue was brought up by a friend who has recently taken delivery of their unit. I was able to reproduce the issue on their unit with their set of headphones.
The issue was reproduced on my unit with my set of headphones as well
Hi @cfd2 was this ever resolved for you? I seem the have the same in my headphone out. It’s fine through the mix out but pretty poor and almost unusable through the main out.
Not an under the table update, it has been discussed in several threads available in this forum.
As this issue has never been replicated or confirmed and is for a firmware two years out of date, I’m not sure exactly what we’re supposed to do about it. Personally, I would have updated the report to apply to more recent firmware issues to let us know it was current, or raised a support ticket to report a hardware fault. Suffering in silence helps no one and solves nothing.
I will send you this firmware that helped Laezea for a different audio issue (the symptoms did not match yours and appeared with a more recent fw issue) and you can check if it resolves your problem.
My apologies, that came out quite rude due to my frustrations with the unit over the years. As I had mentioned in the report, I was able to replicate it on both units I had access to at the time. If this was never replicated someone could have at least written a message stating that and I would have helped clarify.
I am just unsure what to do since we report bugs on the forum but we rarely get feedback and things appear to get fixed mostly when we create a support ticket instead. This makes it seem like the Bug Report sub-forum is not particularly impactful unless a thread gets noticed by many people. Which one is better?
I’ll check to see if the issue is fixed in the newer hotfix software when I fire up the unit next time, although I can’t promise it will happen soon.
No need to apologise, I understand the frustration when a piece of kit doesn’t work as it should.
The bug reports forum is invaluable for the dev team to fix and squash bugs so please don’t stop using it to report repeatable errors with the machine. I agree that there should be more transparency around whether a bug has been confirmed and squashed, however, so I will look to see what can be done about this in the future.
The support ticket system is for potential hardware issues (as well as any other questions and queries that people may have and can’t find an answer to) - the dev team don’t have access to this (I’m not on the dev team) so I will always advise anyone reporting a bug in a ticket to repost here in the forum
