Thanks for the additional information.
I can't find anyone local to work on it. We already have a Tonematch so it would just be the cost of the L1 Compact
You can call Bose Support to see if they can help you to diagnose the intermittent outages. It's a free call.

Typically, in an outdoor bandstand with 50-100 in the audience. We use two microphones for the chorus and a third microphone for emcee work.
Setting aside you comfort with having used two L1 systems up until now; you might find you can do your shows with the T1 connected to the one L1. The horizontal dispersion of the even a single L1 should reach 50-100 people outdoors.
Have you tried that?
Back to your original question.
I have two L1 Model 1 systems that were purchased 10 years ago for a small women's acapella group to use at small outside venues. One of the power stands has been having intermittent outages. We have been advised to pick up an L1 Compact and use with the still functioning L1 Model 1 running everything through the Tonematch. Will this solution work?
Yes, you can use an L1 Compact with an L1 Model I.
The L1 Compact does not project as far as the L1 Model I, but in an outdoor setting for 50-100, you might not notice the difference.
I would try running with the single L1 Model I before investing more money although you might consider getting the L1 Compact as a backup. It could probably do the job alone in a pinch.
