Missing gain slider

[JPJCoda]

Hi all

I came across an issue last night whilst mixing my band's in-ears that I haven't come across before and wondered if anyone could shed any light on the explanation.
The gain slider on one of the channels disappeared and I just couldn't figure out how to retrieve it.  I had all the channel inputs set to A (mic pre), so that wasn't the explanation.
I've tried to attach a couple of photos to show the problem; if I've been successful, it's channel 10, acoustic guitar.
Any ideas would be greatly appreciated.

Many thanks in advance.

Your pictures are super-low resolution, so difficult to see the details, but if I see this correctly, you have the source A set to "None" for your channel. You'll need to assign channel 10 to a physical input (routing page), then you should get a gain slider.

Cheers,

Torsten

Thanks Torsten, that makes perfect sense.  I'll check the I/O routing, but I'm sure you've hit the nail on the head.
Thanks
