Ok...now that I _think_ I have covered off all of the outstanding questions, how about some feature additions and updates?
Volume control: There is a physical volume control knob on the bottom front of the unit behind an access door. This is the same area where the power button, USB ports, and indicator LEDs are located. The volume control only works on the analog input. This allows you to plug something like a CD player directly into AxiomAir, even though most CD players do not have a volume control. The same goes for some TV analog outs. For all of the digital streams (AirPlay, UPnP, web radio, NAS, USB, etc.) the volume can be controlled from either the streaming device or our web interface. We will also be adding a maximum volume level setting with password protection if you'd like to limit listening levels...for the kids or maybe your visiting Mother-in-law who insists on rocking out too late into the night!
3.5mm jacks: We have had a large number of backers ask about using AxiomAir with their TV. Of course this is possible as long as your TV has an analog output. In order to make the connection cleaner, we are adding a duplicate 3.5mm jack on the back of AxiomAir to easily allow you to hide the wires. This input is in parallel to the 3.5mm jack on the front, so you can only use one at a time. Selecting the analog input, rather than the digital stream, is via a button on our web interface. This means that you can leave an analog source like a TV or CD player plugged in all the time and switch between it and streaming audio remotely.
Spotify integration: Maybe...fingers crossed!
TIDAL integration: YES, AxiomAir will have it!
Rdio integration: We have not really looked closely at Rdio yet as it seems to be a less popular player in the streaming music marketplace, but it is something that could be added if there is demand sometime down the road.
Thanks,
Andrew
