L1 Model II

Let's talk about the L1® Portable Line Array Systems

Using proprietary Bose® technology, L1 systems combine  PA and monitors into a single, highly portable unit. The  loudspeaker can be positioned behind or to the side —and you hear what the audience hears.

Highly portable PA and monitor combined for solo performers, DJs and general-purpose use. Fixed vertical control with 180° horizontal coverage Reduced vulnerability to feedback.

Three systems to choose from (Compact, Model 1S, Model II)
Two passive bass module options (B1 or B2)
Consistent coverage and tonal balance, portability and easy setup.

Brand New L1 Model 2 Quit

2 L1 Model 2's  Brand new, first gig...   ran about 10 minutes a very modest volume..  Suddenly the sound became very gritty and distorted and within a few seconds it simply quit..  The power light remained on however the incoming signal shows no signal.   Flipped the the inputs at the board and to verify there is a signal present..  everything is good, connections are correct. No sound..  Help please..

This is terrible news. 

Did both L1 Model II systems fail?

Please tell us about your signal chain - everything that leads to sound coming out of the L1 systems. Most important right now; please give us a link to the owners manual for the board.

Thank you.

Hi Lee,

And a warm welcome to the community from me too.

I'm also sorry to hear about your problem. 

Detailed information about your signal chain could prove to be very helpful regarding trouble shooting. That way we can get an idea of what may or may not be happening. E.g. you mention a board, which I understand as meaning a mixer. ST's request

really is the most important piece of information at present as it gives us somewhere to start.

Just out of interest. Have you tried the board with a different amplifier/speaker system? I ask because it wouldn't be the first time for many of us to buy a new PA, realise that it's not functioning as it should and then start to question the new equipment, only to find out that a piece of the older equipment which had always worked has become defective. In this case, maybe your board has ceased to function properly? Just a thought, especially if both L1 Model II systems failed at the same time (which would be really strange in my mind).

Hope that helps in your search for the problem. And if not, please supply us with the information that ST has asked for.

Whatever the outcome here, I hope that you have a good Xmas and new year.

Hi and thank you for the quick response(s)..  I didn't want to bore you with unnecessary details but you asked...   I previously owned two older L1's. One was the  PS1 variety purchased back in 2006 the second was a later version L1 Model 1 (I think).. 2010 or so.  It looked the same the PS1 only it was a new version.  Recently I had a power supply issue with newer of the two..  After contacting Bose I learned about the customer buy back program and decided that after 12 years of pretty solid gigging it was a good time to think about replacing both.  They both gave me years of reliable service.  No regrets.  The new ones arrived, I set them up at home to make sure they powered up,  I could hear the faint hiss in the towers..  Blue lights were on.. everything seemed to be fine,  At the gig within a very short time 10-15 minutes,  one of them failed while playing an ipod with classic rock. Ray Orbison's 'Have I Told You Lately' to be exact.  I began trouble shooting.. I switched the input signal from the L1 that was still working and applied it to the L1 that wasn't working..... nothing. The green signal light did NOT show a signal present.    Plugged back in the first one again... it worked fine.  

Signal Chain 

EFX 12 Soundcraft  to B52 800 watt Active Sub (single 18) using the hi pass out to L1s.

To rule out any cabling issues I tried running the ipod directly into the L1 with the trim cranked up (I had in it 12 oclock at the time it failed)..  Hoping to hear at least a little something with my ears against the towers....but nothing.   

I think I need to send it back.

  

Hi Lee,

Thank you for all the detailed information. That was helpful. The only thing that comes to mind - is the possibility you were running stereo signals into the L1 Model II analog inputs (that are balanced mono). That won't work. Your older L1 units had unbalanced mono inputs - and those tolerate a stereo input better.  But the difference in wiring doesn't account for all your troubles.

At this point it's best if you call Bose Support on Monday. They will help you.
