Pro amps officially better than consumer amps!

Got it confused again. Sorry. What I mean is XLR or balanced to RCA. RCA from the prepro or receiver to the amp XLR ( if such a cable exists ) this way like I said above I wouldn't need to hunt for a prepro that has balanced outs and I could get a lower priced receiver! Does this make sense?

Yes that cable does exist. You wouldn't need it though because the amp has rca inputs. Bottom line, you don't need a processor with balanced xlr inputs.

Isn't there some Signal attenuation using RCA? I remember reading somewhere that big daddy had to buy some device to boost the signal on his behringer amp bc it was too weak

Read that thread Big Daddy linked (especially the section he talked about) and it should help you understand why he needed the converter.These Crown's can be driven just fine with just your average RCA pre-out on AVR's though.

He pretty much has me convinced to give Crown a shot. I like the QSC, but after that testimony...I'm about ready to give it a shot.

Yes, there is a reference voltage difference between XLR and RCA. Also, when you use an XLR to RCA cable, the end result will be unbalanced and you lose all the advantages of balanced connection.

An alternative way when you are connecting an unbalanced output to a balanced input is to use a converter box. I use two Samson S-Convert converter boxes to connect the preouts from the receiver to the pro amps. They were around $50 each. All of this is explaned in the middle of Post #1 in the Behringer Pro Amplifier thread.

Samson no longer makes the S-Convert boxes. You can buy the Art Cleanbox Pro or Rolls Promatch converter boxes.

Yes I do remember reading your thread about that! Im wondering if the reference voltage levels would differ in other amps besides the behringer models as Cembros hasn't mentioned any problems with his RCA lines

I don't have any problems but I do have to set my levels pretty high, around +8 with the gain at the 3 o'clock position.

This has absolutely nothing to do with Behringer or any other type of amplifier. It is just a difference in voltage levels between balanced (XLR) and unbalanced (RCA).

Well I have all my speakers installed with the center hooked up to the receiver. It is seriously lacking power so it looks like I'll need to pick up another amp. It's also on the floor which isn't helping but I need to get my TV wall mount before I can change that.

Surely you dont mean the speakers powered by the Crown amps are lacking in power!?

No - he's talking about his center channel lacking power because it's hooked up to the receiver He's got to get an amp for the center now.

You sir are correct. Have to get it off the floor too.

Oh I see. Crown 1500 should do the trick. Addicting, this hobby is.

Make a DIY centre stand?

No need, it has a stand. I'll put it ontop of my standout designs horizon cabinet, I'm just waiting for my TV mount to come in.

Guys, does anybody know what type of video processing chip the Emotiva XMC 2 offers? And, simply, is it good!? I noticed the Emotiva UMC 2 doesnt have any video post processing capabilties. Neither does the Outlaw 975. They both pass through the signal to the display. At $1499 I would hope the XMC 2 has some sort of video processing feature for 2D and 3D. The other affordable prepro ive looked at is the Marantz AV7005 which has balanced outs ( Yay! ) but i cant seem to find any comments about its video processing either, like if its blessed with a Qdeo chip, or anchor bay chip, etc.

Wondering if you guys could share some insight into this debacle of mine :S

Would it make sense if i added a DVDO edge or iScan Duo to the mix? As a video processor between the prepro and tv display? Atleast that way I can upgrade each component if somethign better comes out without having to worry about adding something i dont need?

Cemrbos, what do you got going on bro? How does your setup look like?

Im also about to purchase my first set amplifiers! Woohoo! What i have lined up are three Crown XLS amps. Right now im finding out which amp would be best. Deciding how many watts i would need and if it makes sense to get the 2500 over the 1500. Both have the same S/N ratio but the 2500 has about 500 watts more in bridge mode ( 8 ohms ) and 140 watts more in two channels...hmm...since a 3 db increase requires twice the amount of wattage, i would only get that bump in performance if the XLS 2500 amp gives me 2x the power of the XLS 1500 in 2 channel mode or bridged....So....two channels I would need atleast 600 watts ( with the XLS 1500 of 300 watts and the XLS 2500 of 440 watts ) to get a 3 db increase and bridged I would need exactly 2100 watts to be 3 dbs louder. If im right, i guess it makes sense to just get an XLS 1500 for each channel since the change in decibels per wattage would be minimal at best ?

All in all that would be about $1197.00 according to parts express. Not too bad for 1050 watts per channel of clean, unadulterated, dynamic, powerful wattage!

What speakers do you have again?
