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.

Stereo Operation

I couldn't find an answer to this so I'm hoping someone out there knows...
I see that the T1 has a pair of stereo inputs. Does the L1 II have the ability to reproduce that stereo image through the alternating L-R angling of the drivers or are those inputs summed to mono?

AW NUTS! I guess I'll have to wait for L1 III! Big Grin When I first bought my system three years ago I was dissapointed that I would be unable to make use of my stereo rig that I had paid so much money for. I like lush, swirly stereo chorus and tremolo and stuff but I don't want to buy two Bose systems in order to do it. Sometimes I bring my stereo amp and use it with the L1 just to get that swirl.
interesting point. Wonder what the bose folk might have to say if an array as this was stereo and how it would differ from as it is now. perhaps some thoughts on why it would or wouldnt work in the design. I had often thought on the original classic i own how the sound would be affected if every other speaker was split left and right, with the left and right being driven by separate amps in the base to create a stereo stick.
You know, if we think very simply about the stereo image (this, understand, from a very much NON-sound engineer), typically the sources, L and R, are physically split and either pointing the same direction or angled in slightly. Should the alternating speakers in the articulating array have channel separation, then each channel would be directed outward. However, depending on the venue and reflective or absorbing surfaces, the bounce back might be significantly interesting.

I think, again very simply, we just can't get good stereo separation from a single source. Let's look at another Bose product - The Wave Radio. It's split left and right, but it's only what? 18" wide or so? Does that stereo separation really make any difference there?

Obviously I don't know enough about stereo and how it is beneficial with chorus and tremelo and other effects. Just a few thoughts.
yea i agree on how it would send stuff left and right. However with the coverage of the L1 to me it would seem that it would just give everyone the sorta sweet spot. I am speaking of the L1 original classic. may be different with the angled speakers in the new model.
not sure how it would affect effects in its use. but curious to know if there would be a significant difference in sound in the stereo stick as opposed to summing everything to mono as it works now when one inputs left and right stereo source into the L1.
I'd like to hear that, too.

Here's a thought for ya. Imagine a totem pole. All of the faces talk or sing at once. When facing it, on any axis, there is no separation. And off axis, the sound falls off. If you turn your head sideways, you'd have to get very close to the pole to hear specific voices.

Another more animated illustration - A bunch of cheerleaders during a time out at a basketball game at center court, and you are sitting at the scorekeeper's table. The narrower the mount, the less able you'll be to differentiate voices. But with a pyramid, with a wide base, you may well hear the individual voices left and right (gym acoustics aside).

I am thinking about a choir now, several rows deep by however wide you wish. Depending on how the conductor has them arranged, in part, determines the balance. They are probably curved around the conductor, too, at least some. From a distance, it is mass sound, but pretty even on any axis. For the conductor, it is innumerable channel stereo.

Thanks for allowing me to think out loud here. Distance must play a part, I guess. The totem pole is the Classic (and moderately redesigned Model I) and the choir is Model II.
Interesting idea.

The articulation (= angled drivers) is really only effective at fairly high frequencies. At lower frequencies it doesn't really do much and there would no actual difference between "left" and "right".

However, for a "left-only" signal, we'd use only half of the transducer and the line wouldn't be as densely populated as it currently is. This makes a significant difference in the vertical directivity and it would not be as good a line array as it currently is.

In essence you would trade off a slight increase in spaciousness for high frequencies against a significant decrease in line array performance. We considered that very carefully before moving ahead with the current approach.

Hope that helps

Hence, the necessity of a B1 with the Model II for optimum performance. Did I correlate that correctly?
thanks hilmar, im certainly not a guru at this stuff, but i kinda figured as all things in this world it was a trade off....and i agree the choice was sound understanding it now. when comparing highs with the new system, at what frequencies would one ( if they heard the difference) start hearing the improved highs....8k, 10k?...just a ball park figure.
im still happy with the classic, and am curious if the usb connection in the T1 can be used to connect a puter using a daw and route say a vst instrument through to one of the bose channels, or if its simply for upgrading presets, and storing scenes maybe on your computer. i may have posted this question somewhere else but there are so many posts on the new system. so sorry if i have repeated something answered.
also i did grab your analogy, thanks baby blue......
Hi wfs

if the usb connection in the T1 can be used to connect a puter using a daw and route say a vst instrument through to one of the bose channels, or if its simply for upgrading presets, and storing scenes maybe on your computer.

I found and am very excited about this :

Hey Everybody,

I'm laying over here in Amsterdam for a few hours before I fly home (finally...I'm completely exhausted.)

Has anyone talked about the ability to send in two digital audio channels via the USB on the T1 engine? This allows many possibilities not just channels 6 and 7.

Also, you can send two channels of digital audio OUT of the T1 engine and program what's on them!

Neato keeno, I repeato.

thanks tom, i read over the online manual from the site. it appears to me that there is settings for usb in and usb out. the manual did say something about assigning the usb to the channels. the usb out i am guessing is just left and right audio also to send audio to the puter.
my figuring here is that the levls and such could be set in a daw to set the channel trims etc on the channels it was routed to. essentially using the usb as an usb audio in and out interface (left and right). I am guessing that the computer would recognize it as a usb device (the T1). In the case of the L1 being mono one would either sum the settings to one channel, or put left to one channel of T1 and right to another channel of T1, and run equal volumes.
My thinking here is if the latency isnt bad one could easily use alot of soft synth type stuff or other computer effects from the daw if one wanted.
when you get around to it let me know how you interpet the manual. it doesnt go into much detail there from what i read.....thanks though for investigating
So the manual says that you can send USB left & right channels from your computer to selected channels on the T1 via USB.

So I'm trying to think of applications to use this in. I guess you could send backing tracks directly through USB to to the T1 & not take up any channels. That's pretty cool. What other kind of computer audio could you send over the USB?
in simple terms, just running softsynths etc and or electric guitar models within a daw and simply sending the output from the puter running the daw to the T1.....make sense?...basically using the T1 as an external sound card, then sending the signal to the bose from the T1.....thanks
daw is digital audio workstation,,,,think pro tools, cubase, nuendo. ableton live....all are recording programs and some have sequencers built in etc...tons of effects plugins , plus pianos , and other instruments etc...this is something when the first PAS came out i inquired of...and thought it would be the cats meow if it could do this....i think it can now...just a matter of hooking it up.....really cool...opens up a ton of possibilities....
think of reording like strings in a daw....and then being able to play that live along with you when your playing guitar (not that i do much of that),,,but effects and modeling stuff...all kind of mic modeling things available for pcs , macs etc...see where im headin kinda?...i mentioned as i said this the first time i was trying the pas....thught it would be great if it all could communicate with a puter..
also not as fast as firewire, and not sure how latency would figure in.....usb probably will be fine if one doesnt get carried away using tons of plugins and stuff..but if it works usb its a start...this too would make it easy to record your performences also coming out of the T1 usb...send voice to left and guitar to right in a daw...then you could mix each separate and maybe come up with some good live recordings...
dmp? digital modeling processors?...not sure if ya mean like stuff hardwrae now like maybe the mama bear....but essentially the usb connection from and to a puter is just data info i guess...the actual analog and digital conversion stuff would take place in the T1....at least i think....
i am now using a firewire 410 as an external audio interface for my sound to and from puter....it has dig ins and outs, and analog in and out...so all the digital and analog converting im guessing would be done in the T1 once the info from or to the T1 usb
looks as if in the manual when they run something like an ipod, they are using an audio input on the T1....but if the same song was on itunes or some window based pc jukebox....it would seem it could be routed via usb from the puter to the T1.
if all this is possible djs would have the most efficient set up for sure with having all tons of songs to play through the T1 from their computer...there too are software dj things for mixing etc....sure could have a heck of a cd collection of tunes on the puter.
basicallly i think if audio can be fed from the puter to the T1 via usb (as in external sound card) anything you can play and hear on your puter, you could send to the T1 and through the bose
so essentially i can use my firewire 410 now and get anything i want analog into the bose from puter with very good analog sound...very clean...especially compared to an onboard laptop soundcard....this would just be great and not have to carry an extra interface with me if it coud be done through usb. albeit the final signal would still be analog fed to the bose as it is now with my firewire 410...only way to actually get digital audio into the bose would be if it had a digital input on the base..with the converters built into it to change the analog signal to digital to feed the amps im guessing...still if what goes through the bose now is analog, and quiet.....so should anything fed usb id think
think no computer gibberish as you hear when ya crank up some audio through a laptops analog outs from soundcard...you bypass all that....lot of noise there ...you hear it atroshishly if ya run it through a bose that way...but its not the bose its the puter noise
come to think of it....there are now usb cords for direct plug ins to puters from guitars....1/4 inch to usb...im not sure how good they work though...never tried em....again its still all going to be analog(albeit clean)but it would free up some analog inputs on the T1 if needed.
I was hoping that we could help one another by being able to record performances from the T1 (presets and all) and send them to someone else who could play it on his/her L1™ and help you.

This would be great for listening to (gentle coaching on) use of effects, or vocal or instrument technique I guess. Maybe even for laying down the first track of a round-robin collaboration. I understand that the participants would need some of that DAW (Digital Audio Workstation?) software. But it could be a rudimentary start.

I wonder if you could record a vocal dry, and then let others hear it and suggest a preset or effects because those others could play it back through the T1 and run it through the presets and effects until they hit something great.

edit: spelling
