查到了！，官方的解释RX Monitor: When and How to Use ItWhen using RX Connect, some DAWs monopolize the system's audio drivers, preventing RX from playing audio through the same output device.
The RX Monitor plug-in allows us to bypass this. The plug-in acts as an “instrument” in the DAW, and will play audio from RX through the driver being used by the DAW.
This issue generally occurs with Pro Tools HD hardware on any operating system, and most audio drivers or interfaces when used on a Windows system. If you are trying to use RX Connect on one of these systems, but are unable to hear playback from RX, you may need to use RX Monitor as well.
To setup RX for use with RX Monitor:
- In the RX 4 Standalone application, click Edit > Preferences.
- Click the “Audio” tab.
- In the “Driver Type” dropdown menu, select “RX Monitor.”
- Click OK.
To setup your DAW for use with RX Monitor:
- In your DAW, add an “aux” track. The exact name of this type of track may vary depending on the host application.
- Insert the “iZotope RX 4 Monitor” plug-in onto the aux track.
Now, any audio that you playback through the RX 4 standalone application, will be played out through this aux track in your host application’s session.

就是说这个可以用于standalone模式下避免被daw声卡独占，只要在standalone下edit-preferences-audio-driver type中选择rx monitor，就可以了
再在daw中加载这一个效果器，就可以看到status：connected
