Hello Danny Jones,

 

Absolutely.  You don't mention which model(s) of L1 you have.

 

If you have an L1 Pro series (8, 16 or 32), a Model II, or a Model 1s, you can connect via ToneMatch cables.  Run a a ToneMatch cable from each of the Left and Right ToneMatch ports on the back of the T4s to the ToneMatch port on each L1.  See page 12 of the T4s/T8s manual.

 

If you only have one ToneMatch cable, you can run the right L1 from a ToneMatch cable and then either:

  1. Use a 1/4" TRS  to 1/4" TRS balanced cable from the left 1/4" out to the 1/4" analog in (Model II or 1s) or one of the channel jacks (Pro 8, 16, or 32.), or
  2. Use a standard CAT5 cable (computer network cable) for the other connection.  (The ToneMatch cable is a standard CAT5 cable with a heavier jacket and locking shells -- an "Ethercon cable".)

 

If you use the L1 Compacts, L1 Model 1, or L1 Classic (or S1 pro, F1, or any third-party powered speaker) you'll need to have a ToneMatch Power Supply to power your T4s.  Then use two 1/4" TRS to 1/4" TRS balanced cables from the left and right 1/4" outs to the 1/4" inputs of your L1.  (Note:  The 1/4" input jacks on L1 Model 1's and L1 Classic's are not balanced, so you could use 1/4" TS cables.)  This connection method also works with the L1 Pro Series and the Model II & Model 1s, but the ToneMatch cable is usually more convenient.

 

Does that help?

I did it all the time with my model 2’s. Haven’t needed to do it with the pro32’s yet, but easily could 

I too have two L1 Mod 1 systems and am using a T4 and a T8 mixer(s) together. I have only been using one system at a time (until now) and want to set up a 2nd L1 system and run both mixers and systems together. Can this be done and if so, how do I connect the L1's (assuming I can still use the two mixers). Thank you! 

 

Hello dennisobrien,

 

You can use your T4s and T8s together with two L1 Model 1's in a couple of different ways:

 

  1. You can run the left and right outputs of your T4s to channel 3 on each Model 1, and run the left and right outputss of your T8s to channel 4 on each Model 1. You'll have individual control of all 12 inputs, but will have two master volumes to set.
  2. You can run the left and right outputs of your T4s into Aux inputs 9 & 10 of your T8s .  Or, you can do it the other way around, running the left and right outputs of your T8s into Aux inputs 5 & 6 of your T4s.  Then run the left and right outputs of the second mixer to channel 3 of each Model 1.  You'll have to set the levels for the Aux inputs on the second mixer, and if you want to maintain stereo left/right separation from one mixer to the next, you'll need to pan the first Aux input left and the second Aux input right.

There's an illustration of method 2 in the Bose Wiki.  It describes a single T1 to a T8s, but applies equally to a T4s -- just use two cables to connect both left and right.

 

If you are running the L1's behind you, I recommend panning each channel input to only one L1 tower, either left or right.  This will maintain your gain-before-feedback as well as the "cocktail party effect."  Running mics through two towers won't give appreciably more volume but will exponentially increase the likelihood of feedback.

 

If you are running two L1's as front-of-house, or running the second L1 to spread your sound over a wider space (i.e., dual mono), then make sure you keep the towers at least 20 feet apart.  This will reduce the likelihood of multiple source interference.

 

Does that help?

This totally makes sense. I do remember seeing the illustration a while back and (for some reason) could not remember where I saw it. 

 

Thank you so much! 

I guess I would note that when I set it up and configured my T1 to my T8,  using the Channel 9 on my T8 to connect the two mixers, there was no sound coming from one of the L1's. However, when I used Channel 10 (not channel 9) it did allow both L1's to work together. I also was able to use the PAN.
