I've got something that can glow in the dark too! Lots of Pics

Balls, or stupidity, hence the screen name...lol

Never even thougt about the magnet and the computer...but thats about the only place to put it though, I might have to deconstruct my shleving unit to change it up to be able to put the sub elsewhere. But seriously, magnets next to computers are overhyped. The hardrive is over a foot from the magnet, plus, theres rare earth magnets in the hard drive to begin with.... Oh well, if it screws the computer, I guess thats another thing to upgrade then //content.invisioncic.com/y282845/emoticons/up2something.gif.dd110ecf3ae4b76050d87598f2f8de7c.gif

12AX7's are dirt cheap to find, even NOS.

Sovtek 12AX7LPS's are probably the best new production one, but Sylvania, RCA, and Joint-Army-Navy ("JAN" tubes), are really common to find.

Thanks Jim, I will start looking for them once I get some other necessities bought.

You bastard. You make me want real tube stuff. That costs alot more money, **** you. Your as bad as Thylantyr putting ideas into my head!

Looks good though! I want it.

In a couple of months or so, after you've gotten used to the sound, you may want to swap out the stock tubes for something else...those look like 12AX7's? You can find new-old-stock ones on Ebay or at electronic swapmeets for cheap, and they'd sound a whole lot better than the ones that are in there now.

I got a negative reputation for that post.

Who would give a neg rep to you for that???

Well, plus rep for you from me.

How do you like that Behringer Processor? I was going to get one for the DM330i's but then I just bought the 703's which don't need a processor...

 

[ballstothewall 10+ year member]

Well, I just got my ART SLA-1 amp today, dang its a hell of alot smaller than my Behringer one...

Since I didn't get my crossover yet, I have my preamp hooked up to the ART amp, and I haven't noticed any noise/static yet, I played a zero bit track off of my IASCA sound quality CD and didn't hear anyting till it was everything was WAY cranked up. You really cant tell to much of a change in the "warmth" controls, a little, to me it does sound "warmer" than ith them all the way off. Since I don't have my sub hooked up yet, I am kinda fond of the highpass feature built into the preamp. The sound seems nicer than my receiver, but I haven't had enough playing time to say that for sure. It does seem to take an "Edge" off of it though.

 

[ballstothewall 10+ year member]

****it, the right speaker has "popped" like 3 times since I just hooked it up, and it's never done that before. WTF? Time to switch up wiring... and see whats the matter, **** electronics.

Oh, it also has a turn on Thump, which I was hoping it wouldn't have, but it does...

re: speaker popping.

Verify -

If you are using the balanced input on the amp {XLR} with an unbalanced

source {RCA signal}, check the cable.

RCA Output to XLR Input

XLR Pin 1 = Shield ground => connect to XLR pin 3

XLR Pin 2 = Positive balanced signal => RCA center conductor, hot wire.

XLR Pin 3 = Negative balanced signal {now ground} = RCA shield, ground.

If pin 1 and 3 aren't shorted, you may have bizzare amplifier behavior that

pops speakers.

re: turn on thump

System power up sequence;

Sources first

Amplifiers last

System power down sequence;

Amplifiers first

Sources last

There are exceptions to the rule.

Shouldn't "pop" if he did or didn't wire those to together or not. Maybe if there was some build up of signal because of a grounding issue then not having them wired together would cause the problem. Which I guess could arise from a tube device...

If he doesn't have a good connection somewhere with an RCA or 1/4 inch and it might move a little and make connection and then drop connection. Or if he just made a bad cable and the (-), or ground in the other case, is going to ground or even worse to positive then that would cause a "pop"...

How do you have them wired? Do you go from RCA->XLR or RCA->1/4??

I'm curious however, of a case where you would not power up source->amp and power down amp->source? I cant think of one....

 

[thylantyr 10+ year member]

Shouldn't "pop"

If the problem is not operator error, you will get popping issues with sources

that don't have some form of output muting circuit built-into the unit.

You may find lower cost electronics that don't have these circuits and

when you turn on the amp first, then source -> pop ...

The DCX2496 pops if I turn it on last as there is no special muting circuits designed into it.

If you want to avoid source popping either you use power sequencing or

you buy the high end gear with more safe guards built-in. For me, it's

just easier to turn on the system accordingly to avoid it.

I was referring to the mysterious system pops not the turn on thump, that's rather obvious. The biggest problem from going from XLR-> 1/4 or RCA is the impedance miss match which on pro audio gear can cause huge problems because of the open pre-amp drivers with out a buffer circuit behind them.

Even if you have a component of your system that has output muting you should always turn your amplifier on last just in case...

I use a system timer now, but before I had that when I ran my pro-audio gear on my speakers it was MIXER->EQ->Compressor/Limiter->Wait->Amp->Turn up Amp Levels. One never can be too careful.

 

[ballstothewall 10+ year member]

The wiring goes from computer --->XLR--->preamp(xlr's)--->amp(xlr's)

The popping might have user error, it hasen't done it again yet. When I turn on the power to the units correctly, no Thump, that was simple.

The ART amp has a blue LED in the front pannel to signify Power, that thing is bright as hell, so thats gonna get Modded or covered up or something, its annoying. The amp is also pretty dang small, and light, I like it.

The behringer is one powerful fricking amp, just once click off of minimum on gain is about all I needed to power the mains, the fan is kinda noisy too, but it moves alot of air too.

The preamp is pretty cool looking also, the four gagues are pretty cool to see moving, highpass is kinda nice since I don't have a crossover yet so I don't give my mains under 50hz.

Thanks for all yourguys help, more pics prob comming later, gotta figure out where the hell my crossover is now.
