Crown XLS 1000 and Line 6 HD pro problem
by thomas12452 on 2013-01-19 19:52:07

I just bought a Line 6 HD pro and a crown XLS1000. I have the HD Pro going to the crown using the balanced outs to the channel 1 and channel 2 inputs. I have the crown going to my Orange 4x12 stereo cab with speak on to 1/4 cables. It shows that it is getting signal from the HD Pro on my crown but I am not getting sound from my cab. I'm not sure what is wrong. I'm pretty sure its something really stupid lol. I have zero experience really with rack gear. Any help would be much appreciated.

Make sure the HD is set to LINE level...

make sure the amplifier is in the correct mode also...(stereo...bridge mono is not what you want)

When I get home I will make sure it is on line level. I'm pretty sure it is though. Is there anything else that I should look out for orange need to change on my hd pro or crown possibly.  My crown is set to stereo bypass. With both Chanel 1 and channel 2 clip set to off.

Maybe not orange.

Ok, so I unplugged one channel from the crown to the orange cab and I got sound but I get no sound when both are plugged in. My cab says on the back if you want stereo use both inputs so I'm not sure what is going on. Maybe I should be using the unbalanced outs?

meter your cabinet...makes no difference what it says. Does it have any switches?

What do you mean by meter? I checked for switches there aren't any. It's the 400 watt version of the orange ppc412HP cab.

Would the cab running in 16 ohm stereo and the crown power amp running in 8 ohm be the problem. I don't feel like that would keep it from working.

No...You can always go up on the load with a solid-state...

Meter the cabinet...Mulitmeter...You can check the cabinet wiring with one...You can get one at home depot or walmart for $5 to $10...I am wondering if you cabinet is mono...or is the amp set to bridge...hard to say without seeing eveything up close...

From that last picture, it looks like you have the level knobs on the front of the power amp turned all the way down.

Several things could be going on here -- I use the HD500 into my Crown XLS1000 into a single 150W Eminence Tonker 12 inch 8 ohm speaker with good results.

Unless the Pro is different than the HD500 (somebody please confirm yes or no), the XLR outs are at Mic level not line level, The line level switch on the 500 only affects the 1/4" unbalanced outputs on the HD500. The Crown XLS1000 NEEDS line level ( a hotter signal) on either its XLR or balanced 1/4" inputs to get acceptable level out of it.

The ohm load of the speaker will further drop your volume, as the XLS1000 is rated 500 watts at 2 ohms per channel, 350 watts at 4 ohms, 215 watts at 8 ohms. If you run 16 ohm speaker load on it, it will not be silent, but will be down in the dirt especially with mic level signal going in. If you have a shorted speaker or speaker lead, you would have silence, but you'd notice your Crown level meter LEDs red-lighting and shutting down the outputs. If you have an open circuit in your speaker or cabling, you would have silence, but not having the amp shut down. Also, phil_m noted that your level knobs appear to be at zero. That could also be a root cause -- you get no output with the level knobs at zero.. You should see some signal levels lighting up your LED's on the power amp when you're playing into it.

I run XLS1000 at ~100% and control the overall volume level at the HD500 output volume. I use the HD500 1/4" out set at line level to the 1/4" XLS1000 input, and set my XLS input level to ~100%.I just use a regular heavy duty guitar cord between the HD500 and the power amp input. I wish the HD500 would also push line level to the XLR outs, but they don't.

The pic of the speaker shows you have 2 inputs -- you use both and you have 16 ohm speaker load rated at 200 watts -- these are the separate speakers. If you only use one input, you have the 2 16 ohm speaker loads in parallel giving a total load of half -- or 8 ohms, that will be able to take 400 watts, but the amp will give you 215 watts at 8 ohms. You would be able to run your cab at 215 watts with one channel, or something on the order of 500 watts if you bridge your XLS1000. 16 ohms will give you 2 channels of really weak power.

I just had them down in that picture. I have tried adjusting both of them from 0 to about 12 o clock. No sound comes out but it shows that the power amp is getting signal.photo (9).JPG



Re: Crown XLS 1000 and Line 6 HD pro problem
by thomas12452 on 2013-01-20 21:03:27

So should I be using the unbalanced outputs instead of the balanced?



Re: Crown XLS 1000 and Line 6 HD pro problem
by thomas12452 on 2013-01-20 21:09:00

The hd pro has line level for the xlr outs though.



Re: Crown XLS 1000 and Line 6 HD pro problem
by spaceatl on 2013-01-21 06:06:03

probably worth a try...Balanced line isn't buying you anything in a run that short...Actually, the signal is slightly degraded compared to the unbalanced signal in a short run like that...balanced lines are transformed for running long distances...no need to transform in the same rack...

Are you sure your NL4 or NL2 connectors are wired correctly?

You said in your earlier post that when you unplugged one side of the crown that fed the speakers you got sound.  I had this problem myself some years ago.  The solution was re-wiring the speaker cabinet because it had come wired in-correctly.  I think you need to concentrate on checking the speaker cab wiring and connections.



Re: Crown XLS 1000 and Line 6 HD pro problem
by thomas12452 on 2013-01-21 09:16:51

I was actually thinking this myself I'll open the back of the cabinet tonight and see. I'm not sure how the wiring should be though :/.



Re: Crown XLS 1000 and Line 6 HD pro problem
by thomas12452 on 2013-01-21 19:47:24

I'm pretty sure they are wired correctly.



Re: Crown XLS 1000 and Line 6 HD pro problem
by spaceatl on 2013-01-21 20:12:50

So you have a 412 right? and you have one pair of speakers going to it's own jack?...The jacks are NOT jumped together? You can actually measure this with a multi-meter you get from walmart without taking the cab apart...

The ohm setting will give you a reading that is close the actual impedance...You can also measure if the cab is wired stereo or not...you can even use it to diagnose issues with wiring in your guitar...measure venue power...check cable continuity...ect...and all for between 5 to 10 bucks from any Walmart or Home Depot ...really a good tool to have in the tool box...

anyways, "pretty sure" doesn't tell me that much...sorry, you really gotta go though the signal path and be certain that every component is doing what you expect it to...

I don't mean this in a disrespectfull way, but if you don't know speaker wiring then you need to either Google and learn it or find someone to come over and help.  It's not hard to learn and will help you tremendously with amp equipment now and in the future.



Re: Crown XLS 1000 and Line 6 HD pro problem
by thomas12452 on 2013-01-22 09:39:27

Well I know a little bit about wiring not a ton though. My pops knows a lot more than I do about it. He has a multimeter so were gonna check it out tonight.



Re: Crown XLS 1000 and Line 6 HD pro problem
by thomas12452 on 2013-01-23 06:16:37

I think I'm going to rewire the cabinet so I can run both sides at 8 ohms separate them I suppose as if my cab were two 2x12s. If this is possible. Do you think this will work/is a good idea lol.



Re: Crown XLS 1000 and Line 6 HD pro problem

No can do with 2 pairs of 8 ohm speakers. Each speaker is 8 ohms, rated 100W. Put in series, you get 16 ohms 200 watt rating - which is how it is now per pair. Put in parallel, you get 4 ohms, 200 watt rating. The XLS1000 can put out 215 watts to 8 ohms, 350 watts to 4 ohms, and 550 watts to 2 ohms. It's obviously not linear. Crown does not show a power rating at 16 ohms, but it would probably be around 100 watts, unless there is something else going on, like they shut off output above a certain ohm load - can't tell you on that....

If you use single speakers at 8 ohms 100 watt rating - one per channel, the XLS's 215 watt 8 ohm output is more than double the speaker rating. I use a single 150 watt rated eminence 8 ohm speaker, and I'm closer, but still have to watch it, as the amp puts out more than the speaker rating.

Putting a pair of 8 ohm 100 watt speakers in parallel, you'll get 4 ohms 200 watt rating. The XLS will pump 350 Watts at 4 ohms, again be careful and don't blow your speakers....

Your cab has two 8 ohm 100 watt speakers in series to make 16 ohms. When used in mono, it puts the 2 pairs in parallel to equal 8 ohms rated a total of 400 watts, but the XLR1000 pumps out 215 watts to an 8 ohm load.

I could not tell from your photo what the speaker jacks are. The amp is Speakon connector out, but doubt your cab is -- probably 1/4" jacks to plug and switch mono/stereo..... If it were Speakon, there'd have to be a separate swtich.

Had they been 16 ohm 100 watt speakers, you could have 2 parallel pairs at 8 ohms 200 watts, put in parallel for mono to make 4 ohms 400 watt. It would better match the amp specs...

You don't have to worry too much with a Crown SS...I suggest you take the simple approach...wire each pair parallel...More typical 412 cabs use 16 ohm speakers...but even if they are 8 ohm, you will be just fine...turn on the peakx limiters and you should have nothing to really worry about...just mind that the clip lights don't flash too much...



Re: Crown XLS 1000 and Line 6 HD pro problem
by thomas12452 on 2013-01-23 15:22:02

They are 8 ohm. Running them parallel means running the positives from both speakers togethor to the input and running the negatives togethor as well right?



Re: Crown XLS 1000 and Line 6 HD pro problem
by spaceatl on 2013-01-23 15:39:17

right on...You will have a 4 ohm load on each side...just get your Pops to help you meter it out before you plug up to make sure you got everything right...Does your cab have an NL4? If so, you can drop to a single speaker cable...you need quad conductor cable...The NL4 pinout should be on the back of the amp....usually 1-,1+ for channel A and 2-,2+ for channel B...

All of my guitar amplifiers are NL4 modified and my cabs have NL4s also...I hate 1/4 jacks for speaker line...I use 11AWG Cable and the 1000 watt rated NL4s...more for the durability...never have to worry about my speaker cables getting bugarred...and most folks can't "borrow" my cab at a show...



Re: Crown XLS 1000 and Line 6 HD pro problem
by thomas12452 on 2013-01-23 17:54:16

It has 1/4 inputs. I guess they just looked like that in the picture because they are really big for some reason.



Re: Crown XLS 1000 and Line 6 HD pro problem

My bad, I missed the pic you had...might be broken jack switch on the cab dish...I don't trust those at all...IMHO, they aren't worth repairing...switching speaker lines on a spring loaded 1/4" jack is just a bad idea to start with...

If that is the case I would recomend that you get a replacement dish for your cab with an NL4...Then you can drop down to a single cable and be assured you have a rigid connection between your amp and speakers...One cab will cost you about $10 in parts...It's reversable as long as you get the same size dish...

Connector Dishes...just make sure you get the same size that is on your cab now...with NL4 punch outs...

I rewired it now it works and sounds amazing...... Thank you for your help sir .



Re: Crown XLS 1000 and Line 6 HD pro problem

is it at all possible to just use one 1/4 to xlr from the HD Pro to the Crown XLS channel 1 input and then one speakon to 1/4 from the XLS channel 1 output to the Orange to get a 400w mono just like I did with my 6505?
