The inclusion of features such as Pre-Out and Speaker B connections mean that you can flexibly configure your system depending on your requirements. Important Note: When using a banana plug, make sure the speaker terminals are completely tightened before inserting the plug.

It should also work with the new USB 3.0 ports where the PC will simply treat the CXA as if it were a USB 2.0 or 1.1 device. The CXA supports two USB Audio protocols (not the same as the port types themselves) USB Audio Class 1 (which works over USB 1.1 ports and supports up to 24-bit/96kHz) or USB Audio Class 2 (which requires a USB 2.0 port and can support up to 32-bit/384kHz).
