Recent versions of Win10, Linux and Android are known to work, but as of this writing have not been
All this is to say, you can connect the 3d USB-C connector to your host computer to utilize the UAC2
class driver integrated in macOS, Windows 10 (release 1703 and later) and Linux, right out of the box. The
maximum S/R available via the USB port varies with the maximum channel count set for the USB connection.
The maximum channel count can be changed with MIOConsole3d and is stored persistently in the box.
• 4-12 channels works up to 4x rates (44.1k - 192k)
• 4-24 channels works up to 2x rates (44.1k - 96k)
• 4-48 channels works only for 1x sample rates (44.1k - 48k)
This has the side effect that a USB port channel setting of the root box (box #1, connected directly to
your computer) will affect the available sample rates for the domain. If you find yourself unable to set the
domain sample rate higher than your current setting, check the USB I/O channel count of the root box
(see sidebar below).
If your target sample rate is 4x, make sure all USB ports are set to 12 I/O channels or less.
If your target sample rate is 2x, make sure all USB ports are set to 24 I/O channels or less.
The 3d device will appear in your operating system audio preferences as a standard USB class audio device
and will default with direct routes set up between USB and the Analog I/O ports on the box, with the
headphones and analog outputs monitoring channels 1 and 2 from the USB host device.
Configuring 3d USB ports
Configuring the USB port channel allocation on each 3d device is managed from within the
MIOConsole3d application. You can configure the number of channels if you are connected
either via USB or MHLink.
When you make the change, the box USB connection must reset. It will go offline for a moment
then automatically re-connect.
For USB status and configuration details, refer to the
sections of the manual.
