You can use the ToneMatch T4s digital mixer with a stand-alone power supply and connect to any powered speaker system, not JUST the S1 Pro+ or any of the Bose Pro range.
But utilising the included ToneMatch cable and connecting to an L1 Pro8, Pro16 or Pro32, you can power the T4s without a secondary power supply, and there’s no need for an audio cable between the L1 Pro and T4s either.
It’s possible to wirelessly stream to the Pro8, Pro16 or Pro32, or S1 Pro+ wirelessly via Bluetooth – either a single unit, a pair in stereo, or a combination of any two of the speakers.

Take a look at a more in depth answer based on decibels and how that is important.
