Is there a screen that shows the gain for the usb symbol on the superstrip?
How do you know what the usb gain level is?
Wing it with the leds on the upper right of the Qu?
It’s a digital input, so no preamp, so no gain.
You have trim instead, which you can think of as the same thing.
What USB and what use of the USB? The top surface QU Drive USB A or the rear USB B.
If your talking about the QU drive and you have the drive assigned
to the ST3 input channel then the “super strip” gain/trim and the rest
of the controls will control the audio from the QU drive playback.
I just looked at it last night. Maybe I misunderstood the button on the usb symbol and what the knob under it was for.
It certainly looked like preamp gain same as you do in a screen with the other knob when you select the dB level subscreen.

No idea which usb it connects too, but would have guessed that it would be the usb you had selected as shown in the block diagram.
But still wonder where you see a meter or screen that tells you the level it is at.
