Hercules DJControl Inpulse 200

The Inpulse 200 primarily outputs audio through its RCA outputs. To capture this audio for streaming, you'll need to route it into your computer.
Option 1: External Audio Interface: Connect the RCA outputs to an external audio interface that connects to your computer via USB. This will allow you to capture the audio directly.
Option 2: Virtual Audio Cable: If your DJ software supports it, you can use virtual audio routing software to send the audio output directly to Discord.
