    Title:
    Is the ANI always needed?
    Description:

    Question: If I'm using a Dante-enabled system processor or mixer, do I still need to use the MXW-ANI?

    Answer: No! The ANI (Audio Network Interface) is basically a "Dante off-ramp" for your MXW system. It's a way to get analog mic or line level outputs from the APT. But if your system design includes a DSP or mixer that utilizes Dante, then the microphone signals from the APT can be routed directly to the processor using Dante Controller software, having never left the digital realm. 

    There are few things to keep in mind, though, if you are not using the ANI.

    1. The ANI provides PoE (Power-over-Ethernet) on port 1 of its built-in network switch. Since PoE is required for the APT, if you don't use the ANI, make sure to use a network switch that provides Class-0 PoE.
    2. Similarly, any network switch in a Dante network must be Gigabit.
    3. For small, 4 or 8 channel systems, there is a simple to use, quick setup feature that cannot be done without using the ANI. Without the ANI, you will definitely need a computer connected to the system for setup and configuration.

    An example of this type of arrangement can be easily implemented with the Dante-version of the Shure SCM820 digital automatic microphone mixer. The SCM820-DAN is an 8-channel automatic microphone mixer that utilizes patented Shure Intellimix that automatically activates microphones when needed, and turns off unused microphones, vastly improving sound quality. When used with an MXW-APT8, the SCM820 can be selected as an "output device" instead of an ANI, and all the audio paths are routed accordingly. As noted above, PoE must be provided in order for the APT to operate.
