Hi All, I have 2 questions: 1-Am I the only one? 2-Is this normal, or did I change something without knowing? Now, context: normally when I make a chain, I go from input 1 to output 1/2 95% of the time, but I realized yesterday that if I choose output 3/4, it is much more louder in my headphones monitor. Context #2: Nothing is actually plugged in any output, so it might only affect the monitoring (?) in which case I could file a bug. Or is it some sort of hardware limitation between TRS jacks and XLRs ? Cheers ---

Have you tried swiping downward to get the I/O page and checked out the levels of the outputs? ---

I did, they were all to default did you try and got similar results? ---

I just tried mine and get the same…3/4 are louder to the headphones than 1/2. All outputs set the same 0dB ---

do you think I should file in a bug? Is the sound louder if you are actually plugged into monitor or powered speaker? ---

I tried it. If you use 1/2 and then switch a chain to 3/4 it sounds louder through the headphones. If you then swipe down to the I/O page tap on the headphone output you will see it will have level controls for outputs 3/4 as well as the headphone out and if you have bumped up the HP level the 3/4 level will be bumped up by the same amount (mine was 6db). If you reset this dial to zero (just the one for 3/4 on the headphones page) it will work as expected thereafter (i.e. the volumes will be the same for other presets). It’s probably a minor bug of some sort that causes the output to track the HP level on first switch… but once you adjust it on your unit it will be fixed. ---

I confirm it is weird that the output was set higher in the headphone for them, I had no touch anything. CASE CLOSE ---

Neural said this is due to the balanced outs having higher headroom than the unbalanced ones. Not a bug. ---

Just to clarify – XLR OUT 1/2 are balanced outputs while OUT 3/4 can be balanced or unbalanced, depending on what cable you are using. The spec in the manual shows: OUT 1/2 XLR: Max Output Level: +9.5dBu OUT 3/4 TRS: Max Output Level: +15.5dBu balanced, +9.5dBu unbalanced This is why some people see the XLRs as lower output than the TRS when using balanced cables.
