Email I received today from Icron about the Wiranger:
You had previously expressed interest in operating an Icron WiRanger set with USB audio. I am not sure if you ended up getting a WiRanger yet or not, but we have released a WiRanger firmware update that provides support for USB audio devices.
If you have any questions about getting a unit with the correct firmware or about updating your existing unit, you are welcome to contact me. Once you get a WiRanger set with the new firmware, feel free to let me know how well it works as we are always interested in customer feedback from actual customer installations.
Best Regards,
Dan
