Yes!
You may wish to use multiple ORIA Mini's in a single setup, for example, you may wish to use one for both your Main and Alternate Speakers. This is absolutely possible with ORIA Mini.
If doing this, please note that it is only possible to control one ORIA MINI at a time in the ORIA Control Software. Therefore, it is recommended to set up each ORIA Mini separately using the ORIA Control Software and then using the ORIA Mini's as standalone devices, powered by a USB mains adaptor.
If using Sonarworks with multiple ORIA Mini's, only one Sonarworks SoundID Reference License is required; however, you do require a separate SoundID Reference ORIA Mini Add-on for each device.
