Bose t4s power not turning on with usb cable to computer

Bose t4s power not turning on with usb cable to computer Is there a way to use the Bose t4s without a power supply?

Hi Surpreet,

The ToneMatch mixers cannot be powered by USB. You would need to use a power supply, or connect to an L1 Powerstand using a ToneMatch cable, to power the T4S mixer.
 

Hope this helps!
