I have a set of Logitech speakers, specifically the logitech z3 model. I want them to be able to take in multiple stereo inputs (PC, chromecast audio and possibly phone) and output one stereo output. Would this mixer be able to do the job or would I need something else entirely https://www.amazon.com/Behringer-MX400-BEHRINGER-MICROMIX/dp/B000KGYAYQ Thanks.

I would also consider the MSI GS65 https://www.amazon.com/dp/B07BBJKCYG/ref=twister_B07BX2X6RH?_encoding=UTF8&psc=1 and Gigabyte Aero 15x https://www.amazon.com/Gigabyte-14Kv7-BK4-Notebook-Pantone-i7-7700HQ/dp/B078BXSYVH Both are just as good as the Razer Blade 15 if not better.
