philrynhart Posted November 6, 2015 Share Posted November 6, 2015 Can any one advise if: 1. wall plates (xlr) are used between the M20D L6 link (AES/EBU) cable to the first speaker and between each L6 Link to each speaker will break the L6 Link and cause problems, we are considering using AES/EBU cable throughout but having wall plates so that cables are hidden because we are a church.. 2. the distance between all L6 link cables is less than 15mts as specified, but once installed we will not have any optin of analogue XLR connections, is this wise? 3. Finally referring to no 1 above, is it ok to join two AES/EBU cables using neutrik gold pin XLR's or does any join interupt the digital L6 Link and cause problems. Any advise welcomed as a matter of urgency, cables already laid behind the walls are all AES/EBU as specified for the L6 link connections. Thanks Phil M20D and 4x L2m 14mtr is the longest cable run and between speaker 2 and 3 in the system. Quote Link to comment Share on other sites More sharing options...

This is not "from experience" BUT consider that adding wall plates effectively doubles the number of "contact" connections and is the equivalent of trying to connect together three xlr-xlr cables into a single run. L6Link *advises* that any single run should be a direct run with no intermediary connections. As such I think you need to very carefully consider whether the risk of data disruption is worth it for the sake of tidy wall plates. I assume your speakers are going to be hung/fixed so would suggest that the cables are better secured in the walls but tails (of sufficient length) left to reach the speaker connection panel. I'm in the camp of users who recommend sticking within the recommendations given by line6. 2. the distance between all L6 link cables is less than 15mts as specified, but once installed we will not have any optin of analogue XLR connections, is this wise? With installed cables it tends to be the physical connections that degrade (ie the xlr contacts). A backup plan isn't a bad thing but the cable routing requirements for it are totally different to the L6Link. So long as you could manually run out analogue cables should the need arise, I wouldn't see any specific benefit UNLESS you'd want to be able to run out non Line6 speaker at some point in the future. Such a backup system would happily run to wall plates. 3. Finally referring to no 1 above, is it ok to join two AES/EBU cables using neutrik gold pin XLR's or does any join interupt the digital L6 Link and cause problems. You'll probably "get away with it" but it is not recommended for regular usage. I've previously joined 2 (gold plated neutrik aes/ebu) cables in an emergency and didn't experience a problem BUT it's a risk I wouldn't want to take on a regular basis. When the L6Link drops (because of a bad cable or connection) there is a split second drop of sound across the entire speak run AND everything after the break doesn't come back once the M20 has re-enumerated the chain. I had a recent experience where I'd connected an L2m as a floor monitor but used a right angled neutrik xlr and the off centre weight and vibration was causing the connection to be made/broken every few seconds (though I only worked this out after the gig). Sounded really odd out front! Worked out where the break was occurring by looking at the manage l6link screen, whipped the speaker out of the chain (as I thought it was the speaker misbehaving initially) and connected the two xlr ends together. At the next song swapover, after the connection had proved stable, I whipped out one of the two cables and connected directly to the next speaker in the chain to remove the cable to cable connection. As per answer to 1, stick within the guidance given by the manufacturers. Oh, and from my experience, right angled xlr's are not appropriate for using when the speaker is in floor monitor position! (unless you have some way of securing the connectors!!!) 1 Quote Link to comment Share on other sites More sharing options...
