L1 Pro 32, T4s and Sub 2 sudden volume drop

Portable PA
1

I recently got the L1 Pro 32 and Sub2. I also own L1 Model 2 and B2 and Bose TS4 mixer.
I love my Pro 32 system but sometimes I have witnessed a sudden volume drop that lasts a few seconds. I have not used the app for the 32 Pro system. When this happens the TS4 mixer is connected to the tonematch port on the L1 Pro 32. 

I have bought TS8 and used it once with Pro 32 and Sub 2 without volume drop. 

I plan to sell my L1 Model 2, B2 and TS4 but would like to know if the problem is the TS4 mixer or the new system. This never happened while using TS4 with Model 2.

Any suggestions much appreciated.

Hi maegis!

Welcome to the Bose forum, sorry to see you're having an issue with this setup.

This is a strange one. Does the audio drop out completely when this happens, or merely drop to a lower volume?

Also, does this affect all audio or just one/some channel(s)?

How many inputs/outputs are in use on the T4S, and which instruments are you using?

Hi and thank you for getting back to me. The audio drops out completely for a few seconds.
Affects all audio.

Five inputs are in use on T4S when this happens in this order:
Female vocal (ch. 1), Male vocal (ch2), acoustic guitar (ch3), Nord piano (ch. 5-6). 
The only output in use is Tonematch. 

The sudden volume drop or volume loss doesn't happen every time I use the system but it has happened in various locations.

Hey! 

I have also experienced this exact issue on a few occasions now. 

Its completely random from what I can tell.


We also use 5 inputs and also power the T4S using the tone match port. 

I have updated firmware to the latest firmware, and that has not fixed the issue.

 

Out of no where it’ll just lose volume completely and then return after 3-5 secs. However, tonight it dropped out and didn’t return until I cycled the power on the T4S.

 

Please investigate Bose. It’s giving me no confidence in my L1 Pro 32.

Thank you maegis, and hello Jbox92! Sorry to see you're also having this occur, very strange.

 

Are you able to se the T4S with a power supply, and test connecting with an analogue connection to the L1 (1/4") to see if the issue still occurs?

I recommend contacting the Pro support team directly to discuss and troubleshoot this in more depth over the phone.
