I got mine, but it seems to be behaving strangely... maybe I'm doing something wrong?
In summary, the amp is only producing sound from one channel at a time. The particulars are as follows ...
1) From both 1/4" inputs: a) part way in => sound comes only from left side b) fully in => sound comes only from right side
I tried 3 different headphones with the same results, so it's not the headphones, cable, or plug.
2) From the balanced headphone out, sound comes only from the right side (Yes, I confirmed that the headphone is plugged into the Bal output, and not the Lch or Rch jack.)
It's not a channel balance issue - it's producing either normal sound levels, or zero. In all cases the sound is consistent - it's not intermittent with manipulating either the input or the output plugs. I'm using the RCA inputs, in case that matters (my longer balanced cables haven't arrived yet).
Any suggestions for what might be wrong before I contact customer support?

FL_GuyCorrection, point #1 above should read "From both 1/4" _outputs_ ..."

FL_GuyHiya,
I am not having this problem! I cannot imagine what could be causing this. The only tricky aspect of the setup I can recall is that there are a pair of voltage sliders on the back, both of which need to be set to the correct setting. I can't imagine why this would cause the issue you're describing. Hope it get sorted!

WESXFRight, it's not that - I did check, just to make sure :-)
Anyone know what could be up? I've reached out to Massdrop to see if they have any answers or suggestions.
FL_GuyAre you using the same 1/4 adapter with multiple headphones or different headphone cables/adapters? 4 Pin XLR's can be wired differently with some cables/manufacturers. It's unlikely that you are experiencing issues with both your adapters and XLR cable but thought I would ask. More than likely you've got a defective unit but it's something to try if you are using the same 1/4 adapter or XLR cable with multiple 'phones.

ElectronicVicesRight, different adapters or no adapter, single ended jacks, and one XLR (depending on the headphones).

DontDooDadSorry for the delay, had been preoccupied elsewhere...
Yes I did. It turned out to be a cable connection issue at the source, and NOT the amp. The amp is working, and sounds great.
(Which is a good thing, as MD's proposed remedy if it _had_ been the amp involved a refund and waiting for the next drop for a replacement - everyone please be aware that if you _do_ get a bad unit, this seems to be MD's policy).
