T8 and L1 II, really loud beep occasionally
So, I used my "new" T8 last night (i´ve used it one gig before).
But for the first time in my career with Bose L1 (used it for years and hundreds of gig) it occasionally started to "beep" with high volume.
The "beep" sound is like, well like a fire alarm thats running out of battery, it starts to beep as a warning signal that its time to change battery. The sound was like that, but very occasionally, it could be a couple of times right after each other, or could go like 20 minutes between them.
Is there some warning signal within the T8? or the L1 II?
I have been using the L1 with my T1 tone match for years and hundreds of hundred gigs and NEVER heard this sound before.
So what was new and what was the setup last night?
- The T8 was "new".
- We had a Bassplayer last night that we line out from his amp to T8.
- We had a monitor from Aux 1 (but I don't think it was the monitor as we tried to lower that volume a couple of times without getting rid of the beep.)
I tried to on the fly see if there was any signal that went into red, and I noticed that the analog input on the L1 footer sometimes went from green to orange? And the bass sometimes hit the red. The "VU-meters" on theT8 mixer was also nearly hitting the maximum.
Could it be some of the signal that was clipping that made the really loud "beep"? The "Beep" was at the same output level as the main level of the PA. Is there something in the Bose products that can beep?
We also had 2 LED cans, if that has something to do with it?
