USB C Hub, Type C Adapter for MacBook Pro 2019

Hi there, I have a Macbook Pro 2019 model and have a number of USB devices which I would like to use to live stream DJ sets. I need some advice on how I go about connecting these via the new USB C connections. I have a RCA line output from my mixer which I used to be able to plug directly in my older MacBook via the line input - worked perfectly. However, I'm now unable to select the input as a line in. Also, I have an external Go Pro camera which I want to use for the live streams - again this is a USB connection. My question is, would something this device enable me to connect the various devices to the Mac?

Any help would be very much appreciated.
