Dialog for mono Phantom

[Phs]

Dialog will also provide an extra optical toslink in case you need one.
USB is not of any use except providing 5V if you need it like to power Chromecast for example.

I understand the Dialog is necessary for running a pair of Phantoms in stereo. Is there any additional benefit the Dialog provides for a single Phantom however?

Also does it support USB audio yet?

Thanks.
