OK I'm LOST!

Just got two FP10000s and have no idea how to hook up the speaker connectors or the inputs!

What connector can I buy to go from rca inputs on the AVR to the amp. And, do I need 4 of these since am running in 4 channel stereo? I've never used the speakon connectors either but think I can figure them out.

you need an RCA to XLR cable. weree you planning on coming out of your AVR with 4 cables? or do you have a splitter of some sort? otherside, ive seen a few people who have ordered a SINGLE rca to 4 xlr cables, but dont remember where I saw that :/

Ship them over to my house. I'll figure it out for you.

You need to use RCA to XLR cable or converters to hook up your 10kQ.

I believe Edogg did this for his LMS-U setup.

Having been around both pro audio, and consumer hifi etc., I've seen a lot of goofiness with these. There are many caveats wrt RCA to XLR conversion. Who knows what you'll get upon purchasing a store bought adapter, or full length conversion cable.

Here's a superb guide from Rane detailing the various approaches of conversion. About halfway down the page is where the chart is, but it's all a good read.


Good luck

Ok, so I will need 4 cables per amp? I couldnt tell from the manual if there was a way to send the signal to all four channels from only using two inputs. I'm going to need 8 for the two amps and then another two for two more LFE amps. I would guess I'll need a little more voltage too right? I'm using a Denon 4311 with two sub outs.

I bought a crap load of different types of Y splitters for 1/4 plugs not knowing that XLR was my only option. I have access to some 1/4 to xlr too but that is going overboard with splitters and Y cables.

I'm guessing now would be the time to get some EQs for all these connection and need of voltage, does that sound reasonable?

I cant find a 4 to one adapter.

I'm still searching but if anyone knows where to look that would be great
post #1507 of 4389
Isn't just one input per amp needed? And just run the amp in parallel mode?

Not according to the manual. The manual is only like 3 pages so who knows how accurate it is.

I have a 1 to 4 splitter made from signal cable and then used RCA to XLR cables to each channel of the amp.
post #1511 of 4389
I had BJC make me a 4-1 splitter.

post #1512 of 4389
The local guitar/music shop is going to make me two 4 to 1 cables for around $50. That didnt seem like too bad of a deal to me. I got a few splitters for now way can atleast hook them up until next Friday when they will be ready.

Which of these line amplifiers would work best with my Denon and 3 FP10000s? I can get the custom cables to make each amp only have one end from the 4 to 1 cables.

Im running a 4311 and dont need a line amplifier. Maybe try it without one at first??

Yeah thats what I have too but will be using three amps. I will test first but will only know by the way it sounds. I wouldnt know how to measure.

you won't need it if cabled properly.

I'll have one rca to 2 rca female splitter for sub 1 output which will have the custom 1rca-4xlr for FP10000 all 4 channels and 1rca-2xlr for FP10000 for 2 channels. Then on sub 2 I'll have the other custom 1rca-4xlr for FP10000 4 channels.

Then I'll have two other QSC 3602s for the LCRs.

Sound good?

Oh, and I bought 3 three prong twist lock plugs and receptacles today. My father in-law is going to hook them up tomorrow. I'll have all 10 playing tomorrow night . The only treatments in the room are two layers of linacoustic on the front wall and riser traps (3 cutouts on the top riser of two risers).

I have the gain at 44db's, in stereo mode, with the VCL at 150v for both channels, and the mode switch is set to HARD for both channels correct?? Can anyone confirm this please?

I know, I'm worthless but have no idea how to set these switches on the FP10000. I'm running 4 channel stereo. Any help please. I have another 1-8 switches to the right of the one in this picture. Do I just set them the same, thats what I am thinking?

So on mine, there are 1-5 on the left and then there are the extra 8 for the other 2 channels I guess. Will take a pic in just a minute.
post #1518 of 4389
The way I see it is that the first 1-8 is for the 1 and 2 channels and the second 1-8 is for the 3 and 4 channels. So, like this I have it set to hard correct?

If I have time, I'll post pictures of my conversion for you. May not be until I get back from my road trip in three weeks though.

There is zero point/purpose to using a 4-wire connection if all you need is 240V (two hot and ground). The 4 wire is only necessary if you need a 120/240V (two hot, neutral, ground).

OMFG

that's about all I can say right now. I only have the cheap meter that stops at 126db. It's pegged at all over the entire room listening to music with 8 of the 10 playing. The FP10000s are pushing them pretty good. I think I can make one driver distort but not sure why. It should be able to handle music how ever loud I push it. Might be a bad driver or just it's limit. I'm a little worried how it's going to act when get the screen up and start testing really low stuff. I have some pics but Internet is down. Posting from phone.

8 of the 10 what? I thought I've been following this thread pretty good, but I don't remember seeing what you were pushing.

8 Mach 5 21s powered by 2 Fp10000s. 2 more 21s are in the baffle wall but haven't hooked them up yet.

IB is the way to go, so very efficient.
Sounds like you need a term-lab meter

Yeah, I wish I had enough room behind the baffle wall to go IB but there isnt enough volume. The 8 mach 5s have 6.8ish cuft each and the two mal xs have around 5.25ish each. There are two large boxes for the mach 5s and two small ones for the mals.

I'm out of room for 2 more. I did run some wire to the back of the room though just in case I decide on more. I'll get another FP10000 and use 2 channels for the mals though that way I can add two more if ever want to.

What material did you use for the baffle wall? Impressive setup!

Curious about this as well.
