Audio Mixer

Analogue Mixer

Bluetooth input

USB-C audio adapter

Every now and then I need a small mixer.   I have a 16 channel digital mixer however one needs a phd to operate it.   I need a small and easy to explain and operate mixer. In addition, as more and more phones do not have a physical audio connector, I need Bluetooth. 

I used to have one of these but I can't find it

this mixer seems to meet requirements 

Also need a USB-C analogue audio adapter in case people want to use a wired connection.
