In the US, 612-614 is not a guard band, rather it's part of what's still called "channel 37" (608-614 MHz). It's only for radio astronomy, wireless medical telemetry and now white space devices (WSD). Wireless mics/coms/IEMs/IFBs are not permitted to operate there.

Thanks for the heads up. So is the FCC verbiage below no longer applicable?

"...and unlicensed wireless microphones may operate on a portion of the 600 MHz guard band (614-616 MHz) or a portion of the 600 MHz duplex gap (657-663 MHz)."

I have a Focusrite iOS interface that can output high quality sound to RCAs.  There are probably other interfaces or DACs out there with balanced outs.

Of the speakers listed, I would greatly prefer the DXR12.  If you can swing the extra little bit of money, a DSR112 would be even better IMO.
The DSR will play louder but doesn't really have much bass.  Not a good choice for between 80-200.  The DSR's strong point is the CD/horn that doesn't give out like the QSCs and others.  The DXR actually has more bottom and is a better stand alone (no subs) box.  If you had to run a bass though one, or use it as a drum monitor will lots of the bass guitar in it, the DXR would be the better choice.  For front line monitors where clarity of vocals and SPL are paramount, the DSR would win.

So I need to get audio in and out from a Clear Com type system.

Take a look at VCOM.  This system interconnects over the internet any number of comm channels. connected to local intercom systems

By this Ike is saying there are lots of 4W converters to 2W comms. The best is the Studio Technologies series 45, 46, and 47. Clear Com has a more budget friendly device, the EF701, and RTS has the SSA-324.

These will all convert your 4W circuit to 2W, and some of them will power belt packs.

Good solutions...but expensive!!
Thanks Mac

Yep, just need to convert the comms signal the same way you would if you were interfacing it with any other audio gear. 
Yes.
 THAT's the question that I need an answer for.

Wouldn't that just become a 4-wire interface at that point?
Correct.

This looks like a way to use phones as com.
Not what I need.
I want to be able to create a phone bridge com connection to multiple cities using existing VOIP phone systems.

Best way to connect 2-wire comm to a phone is with a telos Link.  It has phone connection and wet intercom connections.  Will answer the phone as well. 

Telos Link

That-1 gets audio out into a mixer and audio in but not to an intercom unless its a Matrix.
As I understand the manual, it requires a "dial up phone line"
Not always available for my application.
That's why I want to use  to the headset connection.
