The original T1 Tonematch mixer will need an audio cable (two if connecting two L1 Pro systems in stereo or dual mono), and an ethernet cable (or Tonematch power supply).
Important: The L1 Pro8, Pro16, or Pro32 can power the T1 Tonematch mixer via the ethernet cable, but won’t do audio. Unlike the much older L1 Model II or L1s, there is no audio transferred via this ethernet connection.
- Power up your T1 via the Tonematch power supply, or an ethernet cable connected to the L1 Pro Tonematch port
- Run a 6.3mm TRS (stereo) cable from the T1 master out, into Ch3 on the L1 Pro.
If you want to run a pair of L1 Pro from the T4s, you’ll need to run an audio cable (TRS 6.3mm or “quarter inch” jack) from the AUX out of the T1 to your 2nd L1 Pro or S1 Pro+.
