Best way to connect T4S mixer to bar's existing XLR speaker system
New to the site. I am a performing musician, effectively a 'one man show'. I am my own sound tech, light tech etc.
I recently purchased a T4S mixer and L1 Model 1s and it's the best thing i've ever done. For 90% of my shows, I use this setup seemlessly and I have no problem connecting and integrating the T4S with the Model 1s.
However, I have a weekly residency at a large bar, and they have their own PA system with speakers in multiple rooms, outside, toilets etc.
Their setup is wall-mounted XLR which connects into their Allen and Heath mixing desk. I don't mind their desk, but my question is:
Is there a way that I can substitute their Allen and Heath mixer for my T4S? How can I connect my T4S mixer to their speakers via XLR? I'm not particularly clued up with this and the T4S mixer uses a CAT5 connector for connecting the Model 1s so i'm just a bit at a loss as to how I can connect this to a non-bose output.
I presume this is possible, and i'm just not smart enough to figure out how.
Could somebody please help?
Thanks in advance!
