using EQ on music streamed from internet

The video only shows how to record windows audio without using input monitoring so it doesn’t explain what you are talking about. I just don’t want to damage my speakers so i want to know exactly what i need to do. So first of all in the totalmix software i route the Software Playback 1/2 to Hardware Output AS 1/2. Then i enable the Loopback on Hardware Output AS 1/2 by clicking on the Tool icon for that channel. Then i enable the Loopback button on the bottom of the channel. Then in Cubase i go to VST Connections and assign the input bus to the Loopback Channel which in this case is SPDIF opt. L/ADAT 1 and SPDIF opt. L/ADAT 2. The windows audio now plays in Cubase. So how can i use input monitoring and make sure that i don’t damage my speakers?
