6. Using the H9000 as a Computer
Audio Interface
The H9000 can stream 16 inputs and 16 outputs to/from your Windows or macOS DAW, serving as a
powerful outboard eects processor for your DAW’s tracks.
6.1. Changing the USB Audio Sample Rate
When using the H9000 as a USB audio device, the H9000 is always the USB clock source and
determines the sample rate. Since this information is not automatically communicated to the
computer, the user must ensure that the H9000’s internal sample rate matches the “H9000 USB
Audio” sample rate in your computer’s audio settings. It is not possible for the H9000 USB Audio
sample rate to automatically follow the H9000’s internal clock or an external clock source (Word
Clock, ADAT, etc.), and the user must always change the H9000 USB Audio sample rate manually.
When switching to a new sample rate, rst change the H9000’s sample rate (by selecting a dierent
internal clock source or changing the sample rate of an external source such as ADAT, Dante, etc.),
then change the H9000 USB audio sample rate in your computer’s audio settings.
If the H9000 detects that the sample rates don’t match, it will mute the USB audio interface and
display a warning in the status bar:
