Topic: Behringer Ultradrive Problems Poll
Posted By: norty303
Subject: Behringer Ultradrive Problems Poll
Date Posted: 02 December 2008 at 8:10pm
Ok, so we seem to get lots of requests about this unit, and also lots of comments about Behringer reliability.  Lots of people think that this is one of the 'good ones' but it would be interesting to see how the stats pan out.
 
I've allowed multiple votes as people have owned/own multiple units with varying outcomes.  Please don't abuse the poll by impoper voting as it skews what might be a useful piece of info.
 
If you vote one of the 'other' options, please elaborate here with the details of the problems, so we can see if there are many common issues.
 
 
I'll leave this stickied for a while then see what we do with it if it produces anything useful.

I've got two. One is magic, and the other one sometimes has no output on output one, a re-boot seems to sort this.
 
My synopsis is that they're a fantastic unit for the price, and a great unit too. (if that makes sense...)

An old batch one, frying egg and then a dramatic 240 volt from the outputs Angry

New one seems fine, constantly expecting it to die now though. Great piece of kit, price is a bonus.

Cast my three votes :)

1st one I had (in 2003 I think and for the saucy price of over £300!) had at least 3 faults, frying eggs, LCD backlight unreliable, flickered, went off or dim etc and first and 4th output would drop out sometimes which required tapping the unit near the XLRs to restore sound and the encoder on the front sometimes went crazy and would jump up and down all over the place instead of in controlled increments, it was quite a state. To be fair it had been uncased most of it's life and toured and behringer replaced it free of charge only days away from the warranty running out.

The 2nd one, the replacement was much better, an op-amp on one of the outputs failed causing the signal to be half leg which wasn't a huge problem and was able to repair it myself. It went on for a few years before developing the frying egg problem intermittantly, as far as I know it's still in use as a 2 way x-over on the non-frying channels in a dodgy bar in south sheilds.

My third and current ultradrive is maybe about 3 years old and has never had a fault and been used many times on dodgy generators etc.

Despite being on my 3rd one I love the DCXs, they're so flexible and nice while they work! Using DRPAs at work makes me appreciate how user friendly and flexible the DCX is. In many ways they're more flexible than DP226 or 224 in terms of the input routing especially.

I have two.
One about 4 years old and one half a yer old.

I have put some plastic insulation between the chase (bottom) and the PCB as soon as i get the units and have no problems at all.

My theory is that because the unit gets fairly hot during use, after some period of use the bottom of the chase gets a little curved towards the inside (closer to the pcb) and start gently touching the pcb. That is the source of the "egg noise".

I have discovered this on a friend unit that started to make that noise, and when you hit the unit it created a "kick sound" on the speakers.

A very easy fix that should hot steer you away from this unit. I find if extremely good value for the money.

Regards

This is interesting (and certainly not a bad idea) though the egg problem is usually associated with the ribbon cables and mine tend not to run hot either. Could it be that when you dissasembled the unit to install the plastic you re-made a bad connection better?

I've cast my two votes.
1- early batch frying egg, fixed by replacing the ribbon cable. I also insulted the bottom of the casing from the inside while I was in there, no problems since.

2- second unit I bought about a year ago, after a few months it went down, giving no output and no display, although the display was backlit. I have recieved a replacemnt which has yet to be used.

I think a lot of the problems where people experience noise on the outputs are actually due to the IDC header/ribbon cable problem.  As you surmise, you have to move/disturb this piece in order to do the other fixes so it's actually a red herring.  The fact that a number of the units (my old one included) had the insulation fix done and then later went on to re-develop the noise problem adds weight to this theory.  Same as fiddling with the XLR's, this causes the I/O board to be moved inside slightly, again, flexing the ribbon cable at the IDC header.

I'm trying to work out how we can do this where people can vote more than once but not have the problems we are.  I think maybe if I make 2 polls - 1 for positive responses, 1 for negative, so if you have had more than 1 Ultradrive and you've had both good and bad experiences then you can vote in both - but only once in each.  We'll then get an idea of the numbers of good ones and the range of problems with the bad ones (as I'll have 6 options for the bad ones to play with)

How does that sound?

Just make it one poll but with the positive and negatives in two sperate sections and like you say, a max of one vote per member in each section---that should make it virtually idiot proof.


Posted By: norty303

Doesn't work like that i don't think Robbo.  I think its setup so that each poll is a distinct thread in its own right, with the option of having a discussion attached.

Could ask everyone who votes to post up how many they have and whats happerned to them?  That way we could see if the poll tallys with tpeoples comments?

Ive got 2, one new one old and never really had any problems, i did have a frying egg sound once ages ago breefly but it went away, i think it may be due to putting them in a rack above a hot amp.

Had 1 unit that I sent out 4 times for the xover losing settings while DJing. They never figured out what happened. After the 4th time, I gave up. I am now using the Driverack PA, and even though it has less features as the ultradrive, i have never had any problems with my DRPA.

Haven't got round to replacing it under warranty.  After reading this thread am quite tempted to have a play around inside with the ribbon connectors to see what happens....

If you imagine the sound of eggs frying, but coming from the outputs of the DCX, thats exactly what it is.  Often if you wiggle the cables in the back or tap the case you'll get a really loud pop.
 
Normally only affects some of the outputs

I have 2...one is a (very) early model and it suffered from a failure to boot on one occasion...Solved by reseating the ribbon cables and insulating the bottom of the case as a precaution.
The other is a later batch one and has suffered no issues whatsoever...

Fantastic bits of kit, great value for money, too, IMHO

I have 2 units.. oneold, but not that old (about 2 years at a guess).. one new (last month)... no issues whatsover with either.
 
I have only ever used a DCX as my own crossover and have little experience with other brands etc.. but when I do come into contact with other stuff (Driverrack etc) I'm always shocked how inflexible they are compared to the DCX and also how awkward they are to use.. when the DCX is childs play in comparison.
 
Top marks from me..
 
Sound quality always seams to be good too..
 
Just wish the limiters went down another 3db or so... my only gripe.

Adambomb: Don't forget the familiarity factor when you deal with other bits of kit though. Those other interfaces will rub up against your expectation from what you're used to, and that will taint your experience somewhat.

I personally find the DCX interface to be good, but basic and not very well categorised, but I know that my regular usage of a DBX and it's clearly defined categories is a major factor in that. For someone who's coming into it with minimal experience or a wide breadth of experience (freelancing, for example) then I'd still wholeheartedly recommend the DCX even though it's not my cup of tea.


Posted By: adambomb
Date Posted: 09 December 2008 at 2:10pm
I agree, to some degree familiarity does play a part... but a 2 char high display as found on most other LMSs is a lot harder to use by far.. much less graphical representation of what's going on.
 
I also agree on the catagorisation of some areas is a little whack... but again, from my experience a whole sh*t load more intuative than the DRPA etc.

I have 3 DCX's, dated 2003,2007,and 2008, the newest one is slow to update the screen and am considering sending it back, I have had no trouble with the 2007, the 2003 was bought second hand for £75 (including a pair of XLR-phono XLR-XLR), this one was fryig a full english but a bit of plastic under the output board has sorted it out.
Also on the 2003 the plastic insulator in the ATA card slot was a little melted - looks like the regulators nearby have been running hot, I haven't checked this on the newer ones.

I happily rack Ultradrives up next to XTA kit and to be honest on 80% of sound systems the limiting factor in sound quality is going to be your speakers, a lot of people will never be able to hear the difference between the XTA and the Berry.

Other than that Audiocore is the only advantage to the XTA, the software is superb. On the flipside the beauty of the berry is that the on screen display on the unit makes programming it from the front panel a dream, much easier than an XTA and I've never felt the need to hook it up to a PC. If you can understand the dbfs units and run it hot to get round the limiter issues the DCX is a sh*t hot piece of kit that for the money nothing else can touch. Strangely I've had more problems with my XTA kit than I have with my ultradrives too.

I have two of these buggers, one has been fine although a bit noisy for my liking, the other went out after being tested from factory in one of my racks, just snuffed it, all LED's light on input A and no output whatsoever, also nothing on display although backlight. Got replacement about three months ago, this thread has reminded me to refit unit and test before use. Behringer agent informed me that Guarentee period is now three years so this may be of some use to people with dead units.
I must say that I find it difficult to believe that 240v could appear at the outputs but am obviously not in a position to despute it because I never witnessed such an event..

unfortunately behringer does seem to get bitten by issues probably relating to not properly field testing kit & resolving small issues then, before it goes out ino the wild.
and evidently their quality control over testing manifactured product for good working order needs to be better. however at the price.. well !

i use certain bits of their kit & dont usually have any problems; also have one of their old 3216 digital mixing desks which serves as a one stop solution for live sound when not using bigger kit & as a does everything backup. both the mixer and the crossover have worked flawlessly here without crashing once; can get a great mix on the lot for the money too ;) ..still prefer analog where possible tho ;) :)

the frying eggs problem; encountered that with one early dcx, transpired to be as noted by others a faulty crimped ribbon cable connector. they probably werent crimping them down properly - or the connectors they bought in werent upto the task. i resolve the intermittent connections with these by whipping the crimp cover off and soldering each wire directly to each terminal to make a PROPER connection ;) ..works a treat if you are soldering iron inclined.

Fair enough, just seemed odd that mains has travelled from psu side to output, without any fuses popping or warning/alarm bells ringing.

Personally, I would have posted the unit up Behringer's Rusty Sherrif's if I found out that Line voltage was present at the outputs and some of my other valuable kit was affected, irrespective of unit cost.

if it was a live short to case, earth cable should of been connected and rcd would of caught that.

I may be able to make 1 good on out of the 2. :D

I've been working with the samplerate converters that these use, and they're a real PITA. Anyone had problems of noise on the output after the source signal is removed?

a little something posted elswhere, but relavent here - it turns out the led meters on the dcx2496 are indeed 'rms':


aprox -30db of pink noise with a 12db crest factor (aprox -18db peak):




-30db rms shows up on dcx 2496 as an 'rms' value :)
not peak !


however, this old matrix 2u600 shows the drive level as (-18db) peak:

Before drawing any conclusions from those photos and description, I'd have to ask:

1. What operating level is the DCX set to? +12dBu or +22dBu?
2. What is the input sensitivity of the Matrix amp?

you can follow the tracking behaviour up and down the scale between the two digi units connected in analog mode.

the dcx is fixed to +22dbu max.
http://www.behringerdownload.de/DCX2496/DCX2496_SPECS_Rev_C.pdf - http://www.behringerdownload.de/DCX2496/DCX2496_SPECS_Rev_C.pdf

the original issue, was that they did not clearly state weather metering on the unit was done by peak or 'rms' average signal level values. it would seem to at least be a close analogy to the latter.

the meters on the matrix amp go abit crazy with the peak tracking & shift to being at 0db at -8db peak signal input & it just manages to evade the clip light (with no load) at -5db peak.
however its meters are ancient & andys always noted that those meters can be a little off sometimes.
itll be a fairly standard value for the matrix senstivity, andy will know this ..its not written on the amp anywhere.

Return the bugger, I had one do the same, could have cost me the whole left side if I hadn't been able to repatch very quickly. First timeout for the thing as well. Behringer returns policy is very good though.

Before you do send it back, plug it in to a PC and try to do the firmware update procedure.

it's ok cheers mate, just got a new one today and all seems in order. They give off quite a bit of noise tho. Never liked the things. Going into an install at the end of summer.

When you say noisy, do you mean mains hum of white noise ?
Just interested to know because I had a bit of hum on one rack but not the other ( 1 Ultradrive per rack ), Spent a few hours rewiring the bugger and its exactly the same, got new Ultradrive for noisy rack and all is well. Put noisy one in good rack, no noise. Racks are identical, even the flight-cases, earthed in exactly the same points, all leads 100% checked and identical, so similar in fact that I had to number them so I knew which was which.
Although the problem is now solved, it's still annoying the hell out of me to find out what caused it.

hmm this thread makes me wonder if i should get one now lol... i have had lots of there gear in the past and still do use some now and i have to admit i have had some of the strangest things happen with the stuff. my board currently is a mx-3282a 32 8 buss ( clearence from guitar center many years ago bought 2 ) and the right channel main will drop out and i have to over drive a channel and it pops in.. have had the thing apart 3 times now same with the other.lol what ever  time for a serious up grade.. for now im oldschool using a dbx xover and thout of buying a dcx.. hmm might still chance it and get one

Does the MX3282 have insert jacks on the main L/R mix? If so, I'd put money on the normalising contacts being dirty, so the send signal isn't being properly connected back to the return, when there's nothing plugged into that insert point.

I've come across this exact problem on Soundcraft Spirit Folio, Spirit Live and Spirit LX7 desks. The excess signal seems to burn through the dirt and make a good contact temporarily.

had a problem with mine since new, i can power the unit on fine the display backlight comes on but no text is displayed on the screen... however the unit is fully functional. If i leave the unit on for a length of time the display magically starts working. if i turn the unit off then on again it works fine... seems to be an issue with cold starts or if the power has been off for a certain length of time.
 
strange... not really that fussed with the issue though.

I've had no issues apart from the one i've just bought for 60 quid, i knew it may be iffy
 
Works fine but sometimes the screen goes blank and A and 1 VU meters light up full like when it boots up, but stay on and it doesn't work. Hitting sorts the issue out
 
Any ideas what this is or should i just be looking for a dry joint?

Cheers

Just got mine from whybuynew.com and although not put a signal through it, it has done this when I switch it on one time - kinda froze on booting. As you tried -  hit it and all seemed well.

Gigs fast approaching so not sure weather to send it back Confused

now you mention it.. our berry is hard to control.... we get maybe one green light on our OPut channels, even if we have 3 or 4 greens on Iput A and B. So therefore when setting limiter we have to be so precise and there isn't much play. it this something we are doing wrong? or could it be a fault of the DCX? I have a V2 edition.
