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.

Hello all, I'm trying to find a definitive answer to which cable type I need to run between my XAir mixer and my Bose L1 Classic system.  There seem to be people who say XLR to TRS 1/4" (balanced) is the right way, others say XLR to XLR is fine too.  I want the best way to connect.  If it's TRS 1/4", is a "balanced" plug and a "stereo" plug the same?  I'm not seeing any labels on 1/4" TRS cables that say "balanced" on them.  Are all XLR to TRS cables balanced?  So confused here, thanks for any help!  Rick

I have tried every way imaginable. The best thing is an XLR “Y” out of the left and right on the back of the X air. Then just use a standard XLR cable into channel one of the classic. This allows you to capture stereo affects, etc. from the mixer and summit down to a single channel on the mono classic.  It’s the cleanest and strongest signal. Also, I have never had a TRS cables stand up to consistent use    I will attach some photos a little later today

Are you using stereo capabilities in the Xair? Since the L1 is mono and it sounds like you’re using just one L1 not sure what the purpose of using stereo might be. I just pan all my channels in my stereo mixer I’m using to one side and take the L or R main out to a single input in the L1 using a XLR cable.

While you could use TRS cabling, I’ve used XLR cables due to their durability. Since the main out of the XAir is XLR, just stick with that style cable. The essential thing is the input for the L1 is balanced, so using balanced cabling is optimum. 

 It really has nothing to do with the stereo image. It’s just about signal strength. If you combine the two you get a stronger signal. Also, depending on which affects you are using in the x air, some of them are designed to have left and right capabilities. if you pan everything to one side you are missing part of the affect as you will only hear what was designed to come out of the left or right side. I am aware that it is being summed down to a single mono feed but you still get both sides of the effect, just mono.  panning left or right assumes that everything is completely equel in all sources. That is rarely accurate 

Hi, Rick  (rlhiggins),

Hello all, I'm trying to find a definitive answer to which cable type I need to run between my XAir mixer and my Bose L1 Classic system. 

Here is some basic information:

  • The Combo inputs will accept XLR or 1/4" plugs
    • The XLR Inputs are
      • Balanced
      • Mic level 
        • Line Level inputs like those from the XAir may be too hot for the XLR input.
        • You can try a -20 dB pad if you the signal clips even when the input trim is turned all the way down.
    • All 1/4" inputs for channels 1, 2, 3, 4 are unbalanced.
      • It won't make any difference if you use 1/4 inch (6.3 mm) Tip-Ring-Sleeve or 1/4 inch (6.3mm) Tip-Sleeve cables if you use the 1/4" inputs on the combo jacks

There seem to be people who say XLR to TRS 1/4" (balanced) is the right way, others say XLR to XLR is fine too.  I want the best way to connect.  If it's TRS 1/4", is a "balanced" plug and a "stereo" plug the same?  I'm not seeing any labels on 1/4" TRS cables that say "balanced" on them.  Are all XLR to TRS cables balanced?  So confused here, thanks for any help!  Rick

If you have XLR cables handy,  try those (XLR to XLR), but if you can't get the signal low enough to prevent clipping, then try a -20 dB pad  

OR

If your cable length is under 20 feet, you can try XLR to 1/4" cables. Even if the 1/4" end is Tip-Ring-Sleeve, you will still get an unbalanced connection because the L1 end of things is unbalanced.

Either way, connect the XAir left and right outputs to L1 inputs 1 and 2. 

Set the ToneMatch Presets to 00

Set the input trims, so you see solid green (occasional flickers of red are ok).

For more information, please see this article: L1 Classic Power Stand

Does that help?

P.S. Here is an article about general principles Balanced vs Unbalanced 

I REALLY appreciate all the replies although they aren't necessarily all saying the same thing.  It did clear up one question I had, that it's okay to use XLR-XLR cables as long as I can set the trim where the L1 Classic system isn't clipping.  I currently have everything panned R and am using an XLR-XLR cable from Main R on the mixer into Ch 1 on the Classic.  The comment about using 2 XLR-XLR cables into Ch 1 & 2 got me thinking if I was leaving "horsepower on the table" by only using Ch 1.  My Classic is from the easliest batch (2003-2005) and it appears all the Classic's have 2 250W amps and a 3rd for the subs.  If that's the case, then plugging into both Channels will double the output of the Bose.  Whereas the XLR Y cable still puts both Main Outs into 1 Classic channel.  

All my reading into the Bose site references uncovered that I have never updated my Presets.  But if I'm using a mixer into the Classic and not direct mic, that shouldn't affect anything right?  BUT what about the Firmware update, is that something I might benefit from?  

Thanks again, it's great tapping into such an experienced forum!  Rick

You're not leaving any horsepower on the table. The amps are not assigned to channels 1 and 2. The amps on the Classic are assigned to:

  1. Upper section of the Cylindrical Radiator®  
  2. Lower section of the Cylindrical Radiator®  
  3. Bass subsystem

The reason I suggested connecting to two L1 channels was to eliminate any anxiety about whether or not you were getting the full benefit of any stereo effects.

Right.

BUT what about the Firmware update, is that something I might benefit from?  

You're not missing anything you would hear. Given you've had years of problem-free service, I wouldn't do the Firmware update.

Nice to meet you Rick,
