Reboot required after initial turn-on

My L1 Model II with T1 has been requiring reboot lately after initial power-up. This used to happen infrequently, but now it’s every time.

I power up the base amplifier, then turn on the T1. Everything looks normal (the T1 indicates signal), but there is no sound. I turn off power to the base, then turn it back on, and everything then works as it should. Symptoms are the same whether or not the T1 power is set to ‘on’ when the base is powered up.

Is this a workaround for a known bug, or might it be the premonition of a disastrous failure?

Hello Rick,

Sorry to hear about your issue. What you are describing is a rare issue that could happen with some earlier firmware revisions.

You can check the firmware revisions of both your T1 and the Model II power stand. The T1 firmware is located in Prefs => Versions and listed as DSP Firmware on the T1 screen. For the Power Stand, it is under Prefs => Versions => Power Stand and it’s listed as “Power Stand Firmware”.

The current revisions are 1.8 for the T1, and 1.3 for the Power Stand. If they are older, you can update them by going to Tonematch Downloads at our website.

If you have any questions or experience further issues, please give us a call at (877) 335-2673.

Thanks, Adam. I’ve been tied up in a couple of heavy gigs this weekend, but will check my firmware revs after all my gear is safely home. Everything seems to be behaving well so far.

I’ve been staying up with upgrades, so I doubt that I’m out of date, but will check and let you know.

Adam,

Okay, the gigs went flawlessly and the Bose L1M2/T1s were well behaved. As always, lots of interest in Bose and the line arrays from audience members.

I do have firmware versions 1.8 (T1) and 1.3 (Power Stand). My power-up issue seems to be intermittent now; if I can reproduce it consistently in some way that will help you assist in troubleshooting, I’ll give you a call. Meanwhile, please post to this thread if you hear from anyone else with a similar issue.

I have that issue as well. Addressed it a long time ago with Bose and never really resolved it. They sent extra equipment, upgraded firmware, etc… Nothing fixed it. Finally just gave up and turned the system on twice. Once it starts working, it does not have an issue.

That’s been my experience, too Mitchell – after the reboot, it’s been stable. If that continues to be the case, I can live with it. I must say that it gave some heart palpitations the first couple of times, though, and I still feel a little queasy when it happens.

Thanks for chipping in with your comments. Lets me know I’m not crazy.

Just wanted to keep this thread alive, since the problem is still here. So far, a reboot has always resolved the issue, but I’d really like to know what’s going on. I’d be more comfortable if Bose recognized this as a known bug and put my mind at ease that rebooting is a guaranteed workaround.

Rick-

This is not a common issue. If it has been persisting even after the firmware has been up to date, please give us a call so we can help you resolve this.

Thank you,

Okay, Adam. It will have to wait until I get the gear out of storage and set up, though. I’ll post with any resolution that results from talking with Tech Support.

Adam,

Okay, the last time the no-sound-at-turn-on happened to me, I flagged the offending L1 with tape, marking all the connected components. We played a date Thursday, and I was careful to assemble the components into the same unit (we have two L1M2s, and I usually don’t try to keep track of the various components). Anyway; bottom line is that the unit behaved flawlessly, with no sign of the problem. It’s always been intermittent, though. I’ll contact Support if it happens again and get their advice.

I also have the same problem with one of my power units (I have 2 Model 1 L2 units, bought December of last year, 2014). Since my units are all relatively new, I hope that Bose would have provided units with the latest software. I do not have T1’s, I use a mixer to feed both units. The point is, I am having EXACTLY the same problems and experiences as “rikart”. Thus I respectfully have to take exception to “Adam-at-Bose”'s comment that “this is not a common issue”, but of course have no way of knowing exactly how many people have now resorted to having to turn it on twice. It’s intermittent, and they do work fine after the second start. I hope it doesn’t get worse. I just had a radiating cylinder repaired, that took Bose months in repair time, and I can’t afford to be without one unit for that long. ugh.

Hi cassdad,

I understand your frustration. It’s really difficult to know how prevalent an issue is. Only Bose can know that. But I might add that this is not an issue that has come up very often here in the forum.

That doesn’t help, I know.

I would call Bose Support and be candid with them about your concerns. Units purchased new in December 2014 are under warranty for two years (electronics) and five years (Cylindrical Radiator®s).

The people at Bose can tell you if the firmware is up to date on your units from the serial numbers of the Power Stands.

As for the long turnaround time on repairs, ask them about that too. You can ask about the current expected time it will take to get the issue resolved, and see if there are any options.

Thank you, ST. I have called Bose service, to no avail. Of course, they can’t fix it over the phone. I just had to use Bose service for one of the radiating cylinders, and it took from Sept 18th to 2 days ago, Nov 13th, for me to get my unit back. In all fairness, the local Bose rep helped me out in the interim, thankfully. However, with repairs taking almost 2 months, I can’t afford the time to send it in for repair - so will just wait until it actually “dies”, or the unit fails consistently, rather than intermittently. Bose’s repair time and process has some serious problems, which I feel is very detrimental to use of L1s for professional use. But that is beyond the subject of this thread, although, as you can see, it is affecting the use.

Sorry about your turn-on problem, cassdad. But I do feel somewhat vindicated in knowing that someone else has been experiencing the same issue that I have.

On the downside: like you, I’ve experienced the problem only intermittently. And, since it occurs on only one of my L1s (as is the case with you, I understand), I don’t think it’s strictly a firmware/software issue, though perhaps there’s a sync problem in the boot sequence that could be solved in firmware. Because it’s intermittent, it will be hard to troubleshoot, and Bose Support is likely to say they can’t reproduce it. Like you, I can’t be without my L1 for extended periods!

On the upside: This has been happening to me (intermittently) for five years now, and so far rebooting has cured it.

Please let me know how Bose resolves your issue. My unit is out of warranty, which a further disincentive to send it in for repair. I’m hoping that the problem can be resolved with a firmware upgrade that all of us can apply in the field.

P.S. ST – thanks for monitoring this forum and providing your always-thoughtful input.

Hello cassdad,

My apologies for the issue! If your L1 Model II’s are from 2014, they should contain new enough firmware as to not have the faulty firmware mentioned in this post. If you could personal message me your information, I’d like to see about replacement or perhaps a loaner T1 to be sure we fix the problem in a much quicker manner for you.

Thank you for your patience,
