Wow. You're lucky to have survived a 120 MPH crash. Sorry about your back injury, though. It's impressive that you've managed to do so much of the lifting and building. Keep up the good work.

And I must say, your AV gear is truly impressive. It will be a dynamic and awe inspiring theater.

Heys guys, Are any of you securing your MA racks with screws into the framing around them to make sure they stay perfectly plumb and level? I'm thinking about adding a few but was just curious as to what others have done.
post #333 of 437
Getting the opening in the framing perfectly plumb and level is the problem. If that is good, don't worry about the rack. I have done 2 of them, and never found a need to screw down the rack itself. However, leveling screw feet on the rack were helpful.

My rack was screwed to the framing. This was partially to keep the rack tight to the framing because I framed my rack in place. I needed as little clearance around the rack as possible because I was limited for space.

yeah I framed the opening just big enough to slide the rack into place. I have about 1/4" on the sides and 1/16 on top. I'll be putting casing around it and as of now (with all shelves in place) it does move around if pushed. Once the weight of equipment is in there it may not move but am affraid that won't stay plumb.

Any opinions for running the LFE to three amps? Two FP10000s and a QSC2450 for right now. So two 4 channel amps and on 2 channel amp that will be replace with another FP10000. Right now I'm just using Y splitters and know there has to be a better way. I still havent bought an EQ so maybe this is the time.
post #337 of 437
Somebody makes 1 x 4 audio distribution amplifiers designed for line-level audio distribution.

But if your EQ box has enough outputs, that would be the way to do it.

Do you plan on using balanced or rca inputs?

We used to use these little "stick-on" audio DAs in broadcasting studio applications -- they work great.

As of right now I have all RCA to Balance xlr cords, RCA to Balanced xlr Y cords, RCA male to 2 female RCA. I've just got a mess going but have enough cords to get some sound going at very least LOL. I've never used the trs circular cables before but not against them just dont know how or when to use them.

I'm really open to everyones input here as I def dont want any hum and with all these connections I'm just making it harder if I have to trouble shoot.

I'm also open to suggestions on all the different EQs!!!!!!!

Throw it at me guys!!

Here is what I am working with.

Denon to 1 QSC 3602 for L & R
Denon to 1 QSC 3602 for C
Denon to 1 FP 10000 for 4 channels driven
Denon to 1 FP 10000 for 4 channels driven

3 temporary options for the 2 malx 21s that will have one channel of another FP 10000 at a later date.

Option 1 Probably the easiest of the 3 and close to the same output

Denon to remaining channel of QSC 3602 for one of the Malx 21s
Denon to QSC 2450 bridged for last Mal x 21



Option 2 I like this option but would need some help matching the channels to be exactly the same. I wouldnt even know where to start

Denon to QSC 2450 running each coil off of each channel. So running 2ohm stereo.
Denon to QSC 3602 for remaining Mal x


Option 3.

Change my center channel from the 2nd QSC 3602 and put it on the 2450. Then run both Mals off the 3602 at 4ohm stereo.

Now after choosing the best temp option help me get the best cable option to hook all this mess up! Please guys.

I'm taking a break from being behind the baffle wall. I've been back there for 4 hours tonight. I've leveled all the speakers, screwed them all in place, and have ran almost all of the speaker wires.

I got the rack as done as I could by myself until the two FP10000 some (hopefully tomo). Rack really looks good to me!

Time to go back out and finish wiring the last of the FTWs. The Mals boxes are drying and will get the wife to help get them in place tomo. I'm shooting to watch a movie Friday night even if I dont have the clones wired with new plugs.

Any and all help with the plugs and receptacles for my 220v 20amp receptacles would be great too. I dont know what type of plug and receptacles to buy nor how to wire them. I have a multimeter and the electrician lives 5 minutes away so if I can get the materials I can get him here pretty quick.

Sorry for all the neediness tonight but trying to wrap it up and really need the good ole boys of AVS

One other thing that I need to do before closing up the wall.

Should I toe angle the L and R speakers? The plans I recieved through AVS didnt mention angling them. The compression driver is in the middle of the screen with the mids above and below them.

Are they JTR T8's?

It just all depends
Aiming in general, and toe angle specifically, is best optimized after everything is up and running. It's a balance of how much acoustic energy encounters the sidewall for envelopment, and a good axial exposure to the primary LP for optimal imaging. The sidewall interaction is oft best done with significant toe IMO, allowing optimal IACC(inter aural cross correlation). One approach is lessening detrimental sidewall interaction between you and the mains, yet heightening it beside/behind you in a somewhat of a diagonal fashion; ie left main hitting right rear sidewall, right main hitting left rear sidewall.

Point being, ideally you're going to need to fine tune the aiming with test material, and/or program material, IMO.

Yeah they are the JTR triple 8s. Dennis confirmed that they dont need any toe in from their location.

Man! I have spent about 8 hours behind the baffle wall in the last two days. I am now officially closing up the few gaps that I've been crawling through with mdf, glue, and brad nails except for one panel that will get screws way I can get back there if I ever need to change out a speaker. All the speakers are screwed in place with L brackets, and the sub enclosures have 2x4s nailed into the concrete with glue between the 2x4s and the enclosure. Hopefully they will all stay where they are supposed to be!

I'm not looking forward to covering the wall in linacoustic either as all the cut outs for the subs are going to be a pain! I'm really wanting to watch a movie this weekend but wont have all the xlr and speakon connectors for the subs

LOL no bites on the sub options.

What about EQ options? I've yet to figure out if I really have to have all four xlr connectors hooked up to each FP10000. I need to download the real Lab manual but cant download pdf files on my laptop (its jacked up). I dont know how many dcx2496s I would need or minis.

yeah I've been posting in the FP thread. I talked to the local guiter/music shop and they are going to make the 4 to 1 cables for $50. Thought that was pretty good deal but honestly dont have a clue what they would cost elsewhere. Bought some splitters and other connectors to use in the mean time.

Could someone tell me which of these line amplifiers would work best with a Denon and 3 FP10000s?

post #349 of 437
I recommend the RDL ST-DA3. This is a distribution amplifier (DA), 1 line-level input, 3 line-level outputs. It will handle either balanced or unbalanced.

You are not needing to change the level of the signals, just prevent the split from loading down the source

If you want a connectorized unit, you could use one channel of the model RU-UDA4 Stereo DA (2 ch in x 4 out, with RCA connectors in and out). As far as I can tell, the FP10000 amps are 4 channel, so you could use 1 channel (1 in x 4 out) for each FP10000.

So, how would the rcas work since the amps all need xlrs? I can go rca to the line level then xlr out to xlr in on amp? Is that right?
post #351 of 437
If you use the connectorized version, I would use RCA-to-XLR cables from the outputs of the DA to the inputs on the FP10000. Just and RCA-to-RCA from the Receiver to the input of the DA.

If you use the stick-on with screw terminals, just buy an XLR-to-XLR, cut it in half, and you have two cables to connect from the screw terminal outputs on the DA to the XLR inputs on the FP10000.

Oh, ok so I could boost 2 my custom 1 RCA-4xlr cables and one other 1rca-2xlr. That sounds good! What are your feelings on sticking with my Denon 4311 until I notice (if I even can notice by ears) or just go ahead and get one since will be using 3 amps from two sub outs along with 2 other amps for the LCRs. I would be willing to bet that I'll need some boost but this will be my first setup with so many pro amps. I've used some line level boosters in car audio quite a few times and was glad when they started making higher voltage head units.

I've never had any of that. Did you get to drink any or did you save them all? I googled it and saw that the last batch was very limited. Are some of them from the last batch? What does it compare to in taste? I like burbon with ice or sprite.

All 4 bottles of Pappy are from the last batch. It was a pain to get and the dealer would only let me buy 1 of each. Luckily someone was gracious enough to say they wanted a bottle of each as well and then handed them to me at the counter and said enjoy

My buddy has a bottle of Pappy 23 Year Old and Pappy 20 Year Old. I ended up giving him a bottle of Pappy 15 to finish the collection. We've had plenty of of the 15 Year old since and the 20 Year Old I went through about half of one of the bottles at Christmas (with family). It was funny cause my dad shot it like a $5 bourbon and I was like

But to give you my comparison. They are like no other bourbon...I've had a lot, my neighbor is quite the bourbon collector and we both fully agree Pappy 20 is the best Bourbon. It has a great flavor and very smooth. At just over a $100 a bottle it is a steal, problem is supply is always short and when they come in they fly off the shelf. I was calling the distributor for weeks and I just happen to be in the area, popped in and saw him unboxing them.

The Pappy 15 is also another great bourbon. Not quite as smooth as the 20 but a hell of a value at I think $65 a bottle. 15 is a great alternative for 20 when you don't want to use up the really good stuff.

Now Pappy 23 Year Old...very hard to find and cost about $250 a bottle...but I might as well be drinking Four Roses or Fighting C0ck. Stuff was harsh and I didn't enjoy it at all. Glad I had a chance to have some just so I can say I did, but I have no ambitions of finding a bottle for myself.

The Johnnie Walker Blue in the center is some great stuff as well. I enjoy it as much as I enjoy some Pappy 20, but the JW Bue costs about $200 a bottle so the value isn't quite there. I have 2 bottles of the JW Blue, but I rarely break them out.

Now for some inexpensive stuff that is really good...the key is to start with Pappy 20 and get a nice buzz, everything afterwards just tastes better. Here is a night shot and a morning shot




The ladies went to sleep and my buddy and I had a really good night. Thats Pappy 20 in the glass to get us started and then we had a bunch of very good and well priced bourbons like Michters, Elijah Craig 18, and Eagle Rare. I really enjoyed the Michters and Elijah Craig

Oh yeah I do all my bourbon with 1 cube, 2 cubes if it is something ridiculous like George T Stagg that really needs to be cut by some water to not burn a hole in your throat. You can mix the cheap stuff with sprite

If I understand what you are doing, it appears to me that you are driving 10 amplifiers (4 ch. per FP10000 x 2, and 2 other amps) from your one subwoofer output. A Distribution Amp is simply a unity-gain buffer amplifier that prevents loading down the source, and prevents a problem in one output channel from affecting the others. For example, you can short one of the outputs and the other outputs continue to work. My guess would be that you will need a DA, rather that simply a wire splitter.

Ok, 8 of the 10 subs are running. OMFG. That's about all I need to say. Interent is down and will post pics of amps and speakers once am able to use CPU again. I'm pegging my cheapo spl meter at 126db everywhere in room. I was able to make one of the subs distort so am a little worried how it's going to handle really low frequencies. Will hopefully have screen up in the morning. I have two more pieces of linacoustic to put up. Taking my time since it's looking good!

I just hate adding extra stuff in the chain but guess they could help until I decide on which EQ unit to get.

The screen is the same price with or without the processors, so I always just include them.
