Where's the recording volume?

Hi… Sorry, but I’m new, and between my mixer and Audacity, I have a jillion buttons and sliders to consider. Smple question. I am trying to record old reel-to-reel tapes on my Mac. The only volume control I can find is on my mixer board. Is there none on Audacity’s control panel? Using Mac 10.12.5 and Audacity 2.1.2.

It’s not unusual for consumer tape machines to have no play volume control and if you have a USB-connected mixer, the Mac and Audacity volume controls will drop out, too. So yes, the mixer is probably it.

Ok, thanks. That’s ok. I just wanted to be sure I’m not missing something on the Audacity control panel.
