Why would it be good to have 2 different types of cables to keep track of? I've NEVER EVER needed or wanted an NL-2. All speaker cables should be 12/4 NL-4, even if you use only one pair. It's not much more weight or size, and is much more future-proof.
I disagree. Put NL4s on your 4-conductor cable. Put NL2s on your 2-C. They look and feel different. Anyone who doesn't immediately see the diff when picking up a cable should not be wiring things.
Part of our jobs as audio rental professionals is to try to reduce our customers problems. If I'm not going to be on their show site clearing up confusion about NL4 vs. NL2, then I'd rather just send NL4 which is compatible with everything.
If I were to start a rental company today, one of the first purchases I would make, even before any inventory, would be a good rental management software package.<snip>There are many good software packages at different price points from developers such as Protonic Software, Navigator Systems or Flex Rental Solutions. Careful choice would need to be made for a start-up company to ensure that the software would be able to scale as the business grows. You only want to deploy a rental management system once!Neil
BUT, if you don't need NL4's, there is a scenario where this could result in equipment damage. If the selector on the speaker is switched to biamp mode, generally, the tweeter is moved to pins 2+,2- on the NL4. If you use NL2 cables, you simply will have a non working tweeter. However, if you use an NL4 cable, and your amp delivers channel 2 on pins 2+,2-, the tweeter will seem to function normally, albeit on a different channel. However, the tweeter is now not running through any crossover. As soon as you turn things up, that tweeter will burn up due to the excessive power from the lower frequencies being delivered.This is actually a somewhat likely scenario to happen. I know I don't religiously check to see if the biamp switch setting has been changed on my speakers each time I plug it in, since I wouldn't have switched it. But that's not to say someone else wasn't dicking with it and decided to flip the switch.NL2 and NL4 cables each have their place.
Sorry, I disagree. When you properly wire your patch panels on your racks you completely avoid this problem. Properly configured racks get I/O patch panels with pin 1 lift switches, pass through XLR's and Speakons that can be configured inside the rack for appropriate patching. They also get, where appropriate, Ethercon. Never leave that up to a client or a hand unfamiliar with your rig. That's when Murphy gets involved.Lee
