webex room 70 dual audio euroblock pin out

[Chet Cronin]

Looking for the audio pin out for the webex room 70 microphone phoenix connection.  I need to make up a phoenix to XLR adapter to my audio distro amp.   Thank you.

The pinout is printed directly on the case above the Euroblock connector. From left to right it is +, -, ground, and microphone mute. See page 26 of the install guide as well:

Cisco also has a pre-made dongle if you prefer to go that route: CAB-XLR-EUROBLOCK=

As @Jonathan Schulenberg wrote, the markings are on the chassis - just make sure you plug the connector in the right spot:

Wiring to a balanced XLR is simple.  Connect the Positive to the Positive, Negative to the Negative, and the Drain to the Drain.

Most equipment that uses XLR these days follows the AES standard, where pin 2 is the hot/positive.
