Hello H2oloo64,


The following article explains the compatibility in detail.  The short answer is the T1 can receive power from the L1 Pro using the ToneMatch cable but the audio signal must travel over a different path.  If you currently use an external power supply for your T1 mixer, then nothing should really change for you.


Hope this helps.
