Hi, Angie Sublime.
Welcome to the Bose Portable PA Community.
I’m also having this problem ... huge white noise when connected to my Bose L1 series 2 PA via the analogue input (as the digital connection is not a viable option according to the Bose engineers)
For optimal gain staging between the T8S and an L1 Model II
- Connect the T8S Main Output to the L1 Model II Analog Input
- Set the Analog Input trim to 9:00-10:00 o'clock. Control the volume with the Master Volume on the T8S mixer.
If you set the input trim higher than 10:00 o'clock, you may have excessive line noise.
- If the Signal/Clip indicator glows red, decrease the Trim level so that it glows only green or yellow.
Control the volume with the T8S.

Other problems are:
R mono out is not mono .... I checked this by feeding a stereo signal to 2 channels panned L & R and muting the Right channel to see that none of the Left panned signal is fed through the mono out....frustrating.
On the back of ToneMatch Mixers, there is an indication below the Right output (MONO).
- Please note:
- There is no hardwired summed mono output on the ToneMatch mixers. Any input signal that is panned hard Left will not be heard through the Right output. To get a mono output please see below.
As you move the pan control away from the center, the sound level increases slightly in one direction and decreases in the other. If you pan inputs hard to one side (e.g., Right) and the Right output will be slightly louder (theoretically, up to +3 dB louder) than if you had panned the inputs up the middle. And panned hard Right - there will be no signal at the Left Output.
T8S ToneMatch® mixer
- Pan all inputs hard RIGHT
- Use the ¼ inch (6mm) Right Output to a powered loudspeaker (e.g. S1 Pro, L1® Compact, F1 Model 812). For best results use a ¼ inch (6mm) jack Tip-Ring-Sleeve cable
- Use the XLR Right Output to powered a loudspeaker (e.g. S1 Pro, F1 Model 812). or L1® Compact with XLR to ¼ inch (6mm) jack Tip-Ring-Sleeve.

Lack of any stereo channels with dedicated attenuator is also a massive oversight ... I have 2 playback devices meaning I’m chewing up 4 channels ... frustrating ..
I'm sorry. Can you get a mono output from the playback devices?
If not, the closest you can get to what you want is to use the Aux inputs 9/10 and pan them both RIGHT. However, except for Level and Pan controls, there is no processing for the Aux inputs. The Aux inputs work best when you will control volume and tone adjustments at the source.
You'll still need two channels for the other playback device.
