Hello DJ Giampy,
Welcome to the forum.
1) Please complete your technical profile as described on
https://www.herculesdjmixroom.com/en-us/forum/en-hardware/028386/
as knowing the user configuration is always needed to understand any technical issue.
2) As you do not describe what you connect where it is uneasy to guess what you do.
You should
a) connect DJControl Inpulse 200 master output to Katana soundbar Aux input, with a dual RCA male to 3.5mm stereo male cable as https://www.amazon.it/dp/B01D5H8KO2/ref=vp_d_pbao_TIER3_trans_lp_B000068O5H_pd 
b) connect the headphones to DJControl Inpulse 200 headphones output.
c) and, in your version of Traktor, choose DJControl Inpulse 200 ASIO as audio device in case your computer operates in Windows 10 or 11 and you have installed Hercules DJ drivers.
Hi, thank you for your answer. I have already bought this cable and I attached it to the input of the Sound Blaster Katana and following your instructions I hear the headphones but I don't hear the audio from the speakers. I also set the parameters with the asio driver you suggested but the audio from the speakers is nothing, am I doing something wrong??? Thank you

- please either describe it these settings,
- or make screenshots of the audio settings.

The forum efficiency depends on your providing clear and detailed technical information, so please also describe where your audio cable is connected (for example: from DJControl Inpulse 200 Master output RCA connectors to your speaker 3.5mm jack Aux input).
Hello,
Sorry but as long as you set your 2.1 speakers as Traktor audio device, you should expect the DJ controller headphones output to play any sound.
To get sound in your DJ audio outputs, you need to set the DJ controller audio as audio device in Traktor.
I do not know the SoundBlaster X Katana, but if it plays no sound when you connect the DJ controller master output in Katana aux input then you should do what any one does to set sound on a new device, test first with a reference audio source:
1) Find an audio source you are sure is playing sound, as a smartphone with 1/8" jack output or an MP3 player,
2) Connect it to the complicated device, the Katana aux input
3) Check if you can hear the sound, and try Katana sound menu unteil it play sound,
4) then once you have finally get sound on Katana, connect your other audio source, the DJControl Inpulse 200 master output to the Katana Aux input, check if you can hear the sound and look in the DJ software menus until you hear sound in Katana.
