Hi Alll, I'm new but I'm after a bit of advice.
We need to split the signal coming from our mixing desk to 2 crossovers. We are planning to run 4 stacks, all focusing in on a central point.
Would something like this do the job? Or would it cause too much of a signal drop or noise etc.

Don't need anything that fancy - an XLR Y-lead will do the job fine.

It's a Fostex LR16. It's far from ideal, we're looking to replace it ASAP with something bigger, but for now it's all we have.

barely anything at all.... go for it
id be more interested how/why you are putting surround stacks in? It causes a lot of cancellations around the room, especially if you used surround bass cabs. General compromise for surround dancefloor setups is to have the main cabs/subs in the stereo stack up front, with midtop only surrounds to 'add/support' the main rig [ie: at a volume to 'topup' the sound to be of a decent level without having to rinse the main rig quite so much]. |

and if it is for live applications, feedback will be a nightmare!! that rear stacks would be pointing towards the stage. Also unless directly in the middle, you will have delays around the room of differences between various stacks. On stage you will get reflections from all around being picked up in the mics.
Not a pleasant experience to the mix/acoustics. |

It's something we wanted to test. The reason we wanted to try the 4 stacks is because we will be doing an outdoor gig in a big dome marquee. Also, we've had problems with noise at the location (it's all above board etc) but off site noise monitoring kept picking us up, thought this might help that situation? Delay shouldn't be too much of an issue front to back, as the digital crossovers we're using we can set a delay on to get it balanced, but I guess it's gonna be different wherever you are in the marquee.There will however be a stage, I hadn't thought about feedback (dumbass, used to doing just DJ setups).

You can't be running this system in stereo so why not just run one desk output to each crossover?
Or if the desk can't be configured for mono output why not configure one of the outputs from the first crossover to feed the second unit. |

sorry to commandeer the thread abit but regarding xlr splitting -
when we use just one mono output from our lms to an amp, always have to bump the gain on the lms to pretty much full in order to get the most from the amp. Would a xlr splitter (so that both amp inputs are used) make this better, or would we need phantom power to boost the signal

phantom power is for mic preamps for +-48v on condenser mics!! you have a really retarded LMS if it does phantom power on the outlets.
and in regards to getting the gain you need, sounds bizarre. Ideally you should be sticking in a hot signal to the input, which will maximise the use of the digital processing bits [think of it like this, if you only feed 50% signal into a 96khz processor, you are only using 48hz of processing, waste!], with a nice hot input signal, you should have no problems with the output gains. |

okidoke, im pretty new to this and obviously had the wrong idea about phantom power haha... ill do some reading ;)
Well I'll have a closer look... other night we had to be careful of clipping the LMS input! and had the output gains on full, and never anywhere near clip on the amps. When we have our normal amps we have enough headroom for it not to matter, was only a problem when we had to make do with smaller amps at a free party on the weekend. Anyway I'll look into it, dont wanna take over this thread
