USB Hub
The MixPre will support multiple USB devices such as USB thumb
drives, Midi controllers, and/or USB Keyboards via a USB hub.
To maximize USB hub support, note:
Powered hubs are recommended as these can deliver appropriate
current.
If using non-powered hubs, do not connect more than three low power
devices.
Connec each USB device individually rather than all at once.
The peak current of all three devices at once may exceed the max
peak current of the supply.
If devices are randomly unmounting there is not enough current to
power all the attached devices. Remove one or more devices or use a
powered hub.
USB-A support (with or without hub) is only available when MixPre is
fully powered and not in low power mode.
Only one USB controller can be used at a time.
Only one USB drive can be used at a time (MixPre-10T only)
When using non-powered hubs with the MixPre-3 or MixPre-6, use an
L-mount battery, a 4-pin Hirose DC adapter (e.g. from Hawkwoods),
a USB-C wall adapter, or USB-C battery pack (e.g. from Anker or
Ravpower). USB-C from a computer may not provide sufficient power
to operate all USB devices connected to a non-powered USB hub.
The USB-A port does not support hubs when being powered from AA
batteries.
Use a high quality USB-C to C cable when powering from a USB-C
power source, preferably one meter or less. Low quality USB-C cables
could cause erratic behavior.
