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.

Hi, thanks for this.  I have a Bose Model 1S (actually 2 of them as I borrow a friends unit when playing a gig).  I use mine in my studio but the 2nd I have access to for playing out.  I have a Presonus RM32AI recording/mixer solution that I currently use for the mixer (all on the computer/laptop/ipad).  The RM32AI box has a variety of output options that I can use for these two Bose units and I'm curious what you might recommend.  Here's a link to the box.

So, there's a Main Output (left/right), there's also a Mono output, but then I also have 16 auxiliary mix bus outputs that I can output to as well. Right now in the studio, I'm using 5 of these for my monitor mix via Alto TX80s (which are cheap but great little powered monitors), plus the Bose which is in the corner).  For the studio, I don't really use the Bose much because the room is a rectangular shoe box and there's just not a great place to place the Bose without one of my musicians complaining about volume.  That said, for some upcoming gigs, I'd like to use the Bose units as our mains in the front of the stage (vs behind us) because the stage is very narrow and probably doesn't have 5-7 feet to put the Bose behind us.   So, back to the question, in your opinion, which output on the Presonus would be the best to use based on this setup?   Also, if memory serves, I read on a post at some point that I should pan all the settings as the Bose is in mono only (so I'd pan all Left on unit and all Right on the other unit to get stereo)?   Thanks for your insights

Hi Rowan,

Welcome to the Bose Portable PA Community and thanks for the interesting questions.

Thanks for all the great information and the link.



So, there's a Main Output (left/right), there's also a Mono output, but then I also have 16 auxiliary mix bus outputs that I can output to as well.

When running two L1 Model 1S systems, I would use the Main Outputs (left/right) in case the room is asymmetrical you need to manage the volumes separately, or you want to pan any of the inputs to one side or the other.

Right now in the studio, I'm using 5 of these for my monitor mix via Alto TX80s (which are cheap but great little powered monitors), plus the Bose which is in the corner).  For the studio, I don't really use the Bose much because the room is a rectangular shoe box and there's just not a great place to place the Bose without one of my musicians complaining about volume.  That said, for some upcoming gigs, I'd like to use the Bose units as our mains in the front of the stage (vs behind us) because the stage is very narrow and probably doesn't have 5-7 feet to put the Bose behind us.   

Will the L1 systems be at least 20 feet (6.3 meters) apart? If so then you can pan everything up the middle. If not, then I would pan each sound source to one side - the side closest to the source. 

So, back to the question, in your opinion, which output on the Presonus would be the best to use based on this setup?   Also, if memory serves, I read on a post at some point that I should pan all the settings as the Bose is in mono only (so I'd pan all Left on unit and all Right on the other unit to get stereo)? 

If the L1 systems are close together, you want to avoid having anything coming through both to avoid Multiple Source Interference

Dual Mono works okay with most conventional systems because they have horizontal dispersion like 90-110 degrees. There's minimal overlap.   As you know, the L1 systems have much wider horizontal dispersion, so we like to avoid too much overlap.

 Thanks for your insights

Ok, so I did the gig with both units.   I think we got some signal cancellation.  So here's another potential solution, let me know your thoughts on this.   In the previous gig, I was using the Bose units as "main" speakers, they were in front of us.  The Presonus has a total of 16 outs (for outputs like monitor mixes - all mono).  So I just assigned an out to each Bose, but I put the same channels in both (for all intents, this is just like assigning a monitor mix).   For the future gig, I'm thinking that I put both Bose units behind me, next to each other (both have B2s as well), but when I assign them thru the Presonus, the channel selections will be different - meaning for example:   Channels 1-12 (vocals & percussion) for Bose unit #1,  Channels 13-24 (drums & guitars) for Bose unit #2.  This way the signals they will be transmitting are not duplicates and should not cancel out.  Does this make sense? Let me know.  Thanks, Rowan

Yes, that makes sense from the standpoint of having each sound source heard through only one L1. I might split things up differently though.

I'd put some vocals in one L1 and some in the other. We want to reduce the number of microphones coming through each L1.  For example; if you have four microphones - put two in each L1 instead of four in one.  This will give you better gain before feedback.

If you put each microphone through the closest L1, that will make it easier for the vocalists to hear themselves in the mix (trying to hear "my" voice out of two voices coming from one loudspeaker, rather than trying to hear "my" voice out four voices coming from one loudspeaker).

The same applies to the guitars. If you have two guitarists, put one in each L1.

How does that sound?

Yes, that's what I have in mind.   For the gig, I have 11 total musicians - about 28/29 total channels, including drums.   Based on your feedback,  I'm thinking of splitting the sound kinda right down the middle - so musicians on the left get the left Bose, on the right the get the right Bose.

The stage is pretty wide, about 30 feet or so.  So i was planning on having the Bose units in the middle of the stage behind the musicians.  Drums to left of that, percussion to the right.   Then about 5-7 feet in front, I'd have the singers (kind of in a row) - with guitars/bass etc.

How would you handle the bass guitar?  Only coming thru one Bose??  I'd think so.

 I'm also planning on using my Alto TX monitors as speakers, maybe put a few in the front to the far left and right to give a bit more fill sound either on stage or for FOH.

 

Thoughts?

Yes, it sounds as though we are of like minds.

Unless there is a compelling reasons not to, I set up two L1 systems behind the musicians like this:

  • Imaginary line up the middle creating two zones of musicians
  • Put each L1 centered, behind a zone
  • Adjust a little either way as required

If the musicians spread out across 30 feet then the middle line is at 15 feet. Each zone is 15 feet wide and each L1 is 7.5 feet from each side. The L1s are 15 feet apart.

If the musicians spread out across the middle 20 feet (5 feet of empty space on each side) then the middle line is at 15 feet. Each zone is 10 feet wide. Each L1 is 10 feet from each side (5 feet to outer edge of the zone + 5 feet to the middle of the zone). The L1s are 10 feet apart.

Yes, bass through one L1 system.

Depending on the venue, you may not need the added fill sound.



Thoughts?
