yes, but you can use non-adjascent ports with standard 3.5mm audio cables - if you are that bothered, assume it's a 3 channel board with an option to upgrade to 6 if you buy the special cables.
They could have brilliantly designed their way out of that by making the whole thing ~1.5cm wider (3mm extra five times).
A zoom h6 is a well designed portable battery powered mixer / audio interface with 4 easily accessible inputs and two that might need an adaptor depending on your cabling. It also comes with two high quality microphones, and records without being tethered to another device. For $409
