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.

Maximum T1 ethernet cable length for sound man use

Hi:

My son, Brad Burns, is a country artist. We have just ordered an L1 Model II, with two B1's and a T1. He sings, plays guitar, and uses an ipod to play backing tracks. All will be via the T1 into the L1 system.

When Brad does his large shows, for 5000 people, he will be using the L1 as his stage monitor.

My question is this: For the large shows we will plug the FOH into the T1. I would like to run a long ethernet cable to the monitor pit at the side of the stage and be able to run his sound for him so he can just enjoy his show. I would control the T1, running his backing tracks, changing his scenes etc....

Obviously I can run his mic cable and guitar cables through DI boxes across the stage to the T1...but how long an ethernet cable can I use to connect the T1 to the L1.

And is there a headphone output on the T1 that I can use to monitor his sound in the monitor pit?

We are extremely excited about the opportunity the Bose system will afford Brad for better sound, ease of setup and clean stage plot....

Thank you all at Bose for your great support of musicians.

Steve,

In another thread, Bill at Bose stated you could run 50' of ethernet cable no problem at all. Success at distances longer than that would start to depend on outside factors, for instance the voltage of your power source.

Another option for you is to run the T1 off of the optional power supply, and then run a balanced line from the Master Out on the T1 to the balanced 'analog input' on the L1m2. This method would be able to transmit over a hundred feet, perhaps much more.

Hi Happy Camp Steve,
Has he considered running his vox and instruments to the T1 as well as the house, via Line Outs, DI and/or XLR splitter? This would give him complete control of his stage sound, rather than what the FOH has, which may be a different mix from his preference.

If in a place where the FOH is required, I'd use the Ethernet cable to send to the L1, and then use the analog output of the T1 to feed the FOH. That way the FOH gets what is heard on the stage (even if they don't choose to leave it that way, it starts with the same signal). That may be easier than trying to "Y" all the various inputs.
Hi all:

Brad's next big concert is Aug 10. We plan on using the Bose as stage monitor. Looks like the 50 foot ethernet cable should work for us to reach from the stage to the monitor pit at the side of the stage.

(Where do we get an armoured ethernet cable that long?)

My next question is: Is there a headphone output on the T1 so I can monitor the mix from the monitor pit on the side of the stage?

Or would it work to take the analog out from the T1 to the FOH...and an auxilliary out (it would have to be identical to the analog out) to another small mixer and listen via the headphone jack on that second small mixer?

We are still excitedly waiting on the T1.We appreciate your advice.

Thanks for all the help! Steve Burns

PS: We just finished the album last week. Previews at www.bradburns.US

Steve,

For the armored ethernet cable: The industry name for one of those is a Neutrik Ethercon. I did a few minutes of google searching and I could not find a place to buy long, assembled ethercon cables retail. Maybe someone else has a source?

If you can't find a long ethercon: If these shows are in a controlled enough environment I would not hesitate to use a regular RJ45 ethernet cable intended for computer use. Youll just want to make sure the ends will not be exposed to a lot of strain or stress. For example, on stage Id take a piece of gaffers tape and tape the ethernet cable coming out of the PS2 right down to the body of the PS2 itself as a strain relief for extra protection.

There is no headphone out on the T1. You have a couple options for this scenario.

1.) Set your aux out send levels on every channel to 100%, and Post Fader. The aux out will now be a carbon copy of the analog master out. Note: The Aux out will not reflect the level of the Master fader unless it is at max. Take your analog master out and send it off to the FOH. Now take the aux out and put it into a mini mixer. You can monitor using headphones off of that. What happens on the mini mixer stays on the mini mixer - the FOH feed is unchanged.

2.) Forget the aux out. Run the analog master out into a mixer, and take a direct out off of the mixer to send to FOH. You can now monitor off the headphone bus of that board. But, anything you modify on the mini mixer will be reflected in the FOH mix.

Which option you choose just depends on how comfortable you are having that mini mixer and the T1 'hot' to the FOH.

Hope this makes sense. Luckily, time is on your side since you have 7 weeks till showtime. Take a look at the T1 flight simulator if you haven't already! That will make some of this more clear.

Thank you for your faith in our product sight-unseen for such a big event.

Hi Steve,

RapcoHorizon introduced Dura-Cat at NSCA 2007. This is a Cat5e cable encased in a thick PVC outer jacket for added durability and terminated with equally rugged Neutrik Ethercon Series RJ45 connectors. I am told that it looks and feels like a high quality microphone cable.

quote:
the Dura-Cat Durable CAT5e cable was designed to overcome installations that may be physically abusive or have questionable environments for normal Ethernet activity. The Dura-Cat offers stranded conductors for patching up to 66-feet and solid conductor cable for permanent link up to 100 meters. The cable can support IEEE 802.3 standards with data rates up to 1000Mbps and Firewire 1394b-2002 implementations for Firewire using 5e cabling.

Dura-Cat is built with a sturdy PVC outer jacket with an outer diameter of 0.34-inches for added durability and terminated with equally rugged Neutrik® EtherCon® Series for RJ45 connectors. The cable contains 4 pair 24 AWG (7/32) TC UTP wire and is ETL verified to Category 5e yielding 8 dB minimum improvement in Near End Crosstalk vs. standard Category 5 and 5 dB better than Category 5e NEXT.


The part number for a 50ft cable is DURA-Patch 50NN. You won't find much on the RapcoHorizon site except press releases as the site is being developed. Unfortunately I could not find any information for the Dura-Cat on the separate Rapco or Horizon sites. Contact Rapco to find out where you can order you cable from.


Hi MikeZ,

Please note in the above quote "The Dura-Cat offers stranded conductors for patching up to 66-feet". I had a conversation with Rapco regarding this statement for which they shared some interesting information.

Their testing has shown that data transmission issues can occur with stranded Cat5 cable lengths exceeding 66 feet. This issue is non-existent with solid conductor Cat5 cable. Therefore, they will not build stranded Dura-Cat cables longer than 66 feet for standard distribution, only for special orders. I don't recall what the transmission speeds were in their tests.

In my opinion, stranded conductor cable is the preferred choice for a cable that needs to be coiled and uncoiled often. The solid version should be acceptable for longer lengths if it is for occasional use.


Edit: Corrected the part number from Dura-Cat 50NN (solid) to Dura-Pacth 50NN (Stranded)
It's fairly easy to make your "Ethercon" cable from any stcok ethernet cable of your choice.

You need to Neutrik NE8MC cable connectors carrieres such as this
http://www.avcable.com/Merchant2/merchant.mvc?Screen=PR...ategory_Code=CONNETH

These attach easily to the ends of most normal pre-assembled RJ45 cables. No tools required.

Please do NOT use the NE8MC-1 variety, as these only works unassembled cables (where the RJ45 plug is not attached yet).

Hope that helps

Hi everybody:

Thanks for the quick reply.

I located "stranded 350MHz RJ45 Cat5e" cable at www.AVCable.com 25 feet for $4; 50' for $6; They have the Neutrik NE8MC as well for $2 each. I ordered those items.

Mike Z:

I think it will be best to use option 1. Take the main out to FOH...auxilliary to mini mixer for headphone monitoring. I say this because going directly from the T1 to FOH presents less chance of adding any extra noise to the signal.If we go from the T1 to another mixer and then out to the FOH there may be more noise.

Also by option one I only have to pay attention to the T1 during the show and anything I do to the headphones won't accidentally mess up the show.

To avoid mistakes, I've learned that simplicity is everything. THAT'S WHY I LOVE THE BOSE APPROACH!! (sorry about shouting, just excited). No separate monitor mixer for me to worry about ..... Brad can just concentrate on his show.... FOH person takes care of their end.

Best regards to all, Steve Burns

(PS: moderator: I'm told that we can't get our T1 until after July 1, maybe. We have the L1 m2 sitting here waiting to be tried out. Any chance of getting a loaner T1 so we can start working on the concert. 5 weeks sounds like a long time but it really isn't for a big show with all new material. Steve Burns)
