Could any one let me know if there is any standard for wiring NL8 connectors I.e are pins 1+ and 1- used for the highest frequency component or the lowest frequency component or is it just user choice? Is suppose the same question could be asked for NL4 connectors

oddly enough, a lot of people go with:
1: bass / mid 2: mid / hi mid 3: hi 4: sub |

The standard is lowest freq first, as already mentioned above. This is from Neutrik's own documentation.
It matters because most large system tops are wired "top down", so if it's a 3-way top, the NL8 input will only be connected on pin sets 2, 3 and 4. 1 will be left so you can pass a bass signal through. A 2-way top would use 3 and 4 (or just a NL4 input). Hope this makes sense / helps. Cheers, John |

As someone said if you ALWAYS use your own rack doesn't matter much, but all systems I've ever used, as said by others, pass from lowest to highest including sub as shown, not with sub on pin 4. The main reason for this, apart from compatibility, is safety in terms of protecting your drivers. Keeping your comps and HF up at +/-4 means your a lot less likely to accidentally throw a wrong and far too powerful signal at it and blow it to hell, where as any wrong signals will most likely get thrown to the subs or lows on +/-1 and be able to handle it. With NL4 connectors its a bit more varied, some companies assuming you'll use "full range" tops on their own and wiring on +/-1 with an internal crossover, some like Nexo on +/-2 to let you pass/pass-through sub, and then some biamped so using both connectors. k Edited by kevinmcdonough - 27 November 2012 at 11:33pm |

Yes kevin that has always made me wonder why they do it like that. But i am just going on what i have found with the majorty of the nl8 based systems ive used.
Surely when you are running larger systems like this you will have seperate lf racks anyway. |

Not always. Not having worked on scoop systems much they may have all their LF amps in one rack, but racks for more standard rock music and big hire companies will usually be mixed. Partly this spreads the power load out through the racks rather than having one big rack drawing 40 amps and the rest tickling along on 5, but it also makes it very modular. So if each rack has say one sub amp, one mid amp and one HF (or whatever ratio is needed for your system) then you can just take one rack for a small system and have a complete set, two racks to double everything for a bigger system, and so on.... k Edited by kevinmcdonough - 27 November 2012 at 11:39pm |
