    I am a drummer/drumteacher and I have a Uad Apollo with audient 8 channel via adat.
    I Make lessons online and do some recordings to people over the internet.
    I miss having a mixer and the Qu-16 look like a perfect partner..
    To be able to record in my small drum studio and take the files on a usb hard disk and mix in my bigger room and
    skip the computer. Start mixer and record in 16 seconds is a five star option to me.
    The clock on the audient that I have as the master is not 100% topclass and I get some drifting audio.
    First of, drums and Qu-16 preamps, do they marry?
    When I film the 48kHz is sweet since that is where cameras are but a lot of audio files sent to me to add drums to
    are often 44,1. The qu 16 is only working in 48 kHz right?
    Whats the workaround on that? I am on Logic Pro x.
    Would the sound/preamps be a downgrade from uad Apollo?
    I only use Steven Slate plugs

    I would say it depends how fussy you are and how well you can adjust the settings.

    Qu records and works at 48, but I believe you can use 44.1 input via the Qu drive directly.
    You could uprez to 192 from 44.1 and then downrez to 48 in your computer first, and then play back into the usb port at 48.

    The preamps are neither better nor worse merely different.

    Just me, but I would prefer the computer to what you describe in the other room.

    Why isn’t your Apollo the clock master? And I highly doubt that your clock master is responsible for drifting audio… or did you mean “jitter”?

    every step of sample rate conversion will degrade general signal quality a bit
    and some algorithms are very bad on this,
    so it is much better to avoid any sample rate conversion if not necessary

    We all know conversion degrades to some extent.
    But sometimes it is necessary.

    Up converting to 192 then down to 44.1 will give better results than going from 48 to 44.1 directly.

    it depends on the algorithms and the signal

    It does not depend on the signal.
    And any algorithm that is not brain dead will do better that way.

    If you have signals close to 0dBFS it will matter which converter is used…

    Only fools have signal anywhere near 0dBFS
    But I grant that the world is full of fools. Some may even be in audio.

    I make sure mine never go over -18dBFS with my studio.
    I chose that limit long before I ever heard of AH and their mixers.

    A&H has 18dB headroom when you hit 0dB on their meter. Wise choice!
    You would have to be a brain dead nuclear heavy metal type to get near zero with the AH gear.

    And anyway, the real problem is AD/DA converters when you are near the limit not the digital conversion of sample rates.
