ZEPHYR XPORT USER’S GUIDE

3 The Details

By now your Xport should be up and running. In this section, we assume you have gotten to know your Xport by going through the Quick Start procedure and brief tour covered in Section 2 (Getting Started).

In this section, we'll explain more about how the mixer works, cover more about using the Auto Dial function, as well as how to use a cell phone for transmission when a telephone line is not available. Finally, we'll show you how you can transmit audio from your computer to the Xport using Ethernet.

POTS LINE JACK

This is for connection to "Plain old telephone service" (analog loop- start) lines. The line inserted into this jack is the most critical part of an Xport installation. It can mean the difference between the remarkable quality of aacPlus and falling back to a voice grade Phone call. Here are some pointers to reliably achieve success:
