    My mistake: the gate was on on that channel. I thought it was off. Yes, with that changed and other settings the same, hissing is pretty loud. If I try to use the gate, it starts going in and out set at about -48db.

    My old 01V may be slightly quieter at the same gain setting, but I have no idea how much gain follows all the way to the phones output for each board, relatively.

    I can’t figure out if there is a way to compare the published specs versus the 01V96.

    here’s a copy of the response from A&H tech support.I guess what they’re saying is I’m listening to the noise floor driven to the max. would still like confirmation from other users that your desk acts the same way as mine, just to rule out any possible fault
    thanks

    Hi John,

    Thanks for the video,

    The Qu has got a powerful headphone amplifier for loud Live situations.
    If you were to pass audio through at the settings shown on your video this noise would not be noticeable
    (please be careful if you do try this at these settings as you might damage both your headphones and your eardrums)

    If you make a recording and play that back you should not notice this noise either.

    the internal gain structure is different than the one in 01V96

    Did anybody tried these settings with connected sources? That’s what counts.
    Plug in a microphone with switch and set up your gain for usable amounts and turn off the mic with the switch.

    The noise should be much lower than in your test.

    HI you would happen to have the signal generator on at a low level. I did that when I was checking everything out and forgot it on in a monitor mix.
