    My PMP500 seems to have developed a problem. When pwered up the unit comes on for a few seconds and then cuts out. It seems the internal fan is not coming on. I assume it may be more than replacing the fan but have no idea as I'm not an electrician.

    Hello!

    I just purchased a nx4-6000 amp. After hooking a stage monitor to it, it went into Protect Mode on all four channels. I unhooked all cables and followed the instructions to reset it, but it still won't do anything. The breaker in the back doesn't seem to have tripped or at least it won't reset. Any ideas.

    Thanks.

      Nigel67 Hi SpideyMan19622. I am sorry to hear that your brand new NX4-6000 has failed straight away. It looks as though you have tried everything possible to get the unit out of the Protect Mode and it hasn't worked. If the unit is still under 30 days from purchase, you can go back to the shop that sold you the amplifier and request a DOA replacement. If older than that, still go back to the shop and they will get the amplifier repaired.

    I bought a spare input board for my 14000 amp direct from their parts dept. However I never used it because it was not the board that was giving trouble at the time. The amp started to give trouble again so I decided to put in the board. It never worked so they replaced it. The replaced one never work also so I ordered another through one of their repair agent. It never worked also. They advised me to ship the amp to one of their repair shops, saying it maybe another issue with it. The repairers told them that the input board is not compatible with the older model amps and it is for the newer models. They refused to take back the two boards and closed my case leaving me with two useless boards. Spending $4000 US for a amp and having these problems does not worth it. Better to buy chinese knockoffs because they help you with parts that can repair their amp.

      Dale_M In hindsight it may have been better to have organise a non warranty repair with an official Lab Gruppen approved repair centre, if you still require assistance please go to the Support tab above and select Service so our team can advise you of your options.

      The amp is at an approved centere in the USA and they are the ones that determine the input boards are not compatible with the older model 14000 amps and the parts department refused to take back the boards. I have two useless boards and a huge bill to repair the amp. That could have been resolved where the amp is used in the Caribbean had they sold me a compatible board in the first instance. If you update the board you suppose to know if it will work on older model amps.

    Is there a recommended replacement fan for the NU3000?

      Nigel67 Hi DanielThompson. Our spares team will be able to advise you pricing and availability for a replacement fan. Please raise a ticket to them. This can be done by clicking on the support tab at the top of the page. A new window will open. Scroll down and click on the Spare Parts tab and submit a ticket. Or if you are looking at another manufacturers fan, the specification is usually written on the fan and you can measure its dimensions. Please make sure if you do go inside the unit that the power is disconnected from the unit. This will void any remaining warranty though.

    I'm using a Behenger HA 8000 VA headphone mixing/distribution amp in a very tight space.

    Would there be any issues mounting it standing upright, on it's end with the channel moving upward?

    Hello, I have a sound reinforcement business in Guayaquil-Ecuador South America.  I need to buy parts to repair an FP7000 LAB GRUPPEN AMPLIFIER.  Where can I find a dealer to sell me the parts?

    We have an installation from 2006 with (2) c48:4, (1) 24:4, and (1) NLB60E Nomad Bridge.

    The NLB60E is (EOL). Is there a new nomad network that these amps will work with?

    If so, will I need to do any firmware updates on thes amps?

    Hi,

    All my old email addresses and contacts at Gruppen get bounced?? Mind you its been some time requesting info.  Ive joined up the music tribe now do hopefully there is somebody is willing to help me.

    I run a service repair business in victoria Australia.
    I currently have a E-Series power amps from a church install from NSW which are obviously out of warranty. I have a temperature related issues where CH2 after 15 minutes begins to splatter and eventually cuts out.  Led signal indictors shows valid Signal although when the level is increased on the faulty channel the amber limit led flashes. Can hear the level although its very very low. I’ve tried freezing components on the signal board however i believe its Class D issue not confirmed as yet.
     
    I’m making a 8-way IDC signal input extension cable to swap channels to determine if its signal board is the issue or its the class D amp? Parts on order to do this.
     
    I was hoping to get a service manual to make things easier to track the fault down with the oscilloscope.
     
    Im happy to sign a confidentiality agreement if that works? Have done for many other brands in the past.
     
    Hope your able to help.
     
    Many thanks
     
    Rob

      Nigel67 Hi EightyHD. I am very sorry, but it is against Company policy to send out Service manuals to any one apart from our partners and repair centres. Australis Music Group in Sydney are our repair centre in Australia.

      Thanks Nigel67 for you answer. I was expecting some response to say we have one and only service centre for the whole of Australia. Glad this approach isn't upheld for an imported car as you'll have to transport it to Sydney and wait 6 months to have it repaired, I feel the ideology behind one service center "Music Group" for every known product on the music tribe list is short sighted and not in the best interests to the products customers? Then again, does Lab Gruppen or product X actually notify in writing if their product develops a fault 'out-of-warranty' it can't be repaired locally? Please reconsider, as I've expressed initially to indicate I'm happy to sign a CA on a service manual just as I did with FP series way back? In addition, why do I have to sign-up with Music tribe just to be able to communicate with Lab Gruppen..? I'll try my best to request the info from Music Group however I'm guessing a similar response, that they don't give service info to the public? Abet being a business and service tech for the last 30 years in the broadcast industry. Thanks anyway.. Failing this, I'll have to nut it on my own :-)

    I have a speaker that is wired using an nl4 speakon. 1+ 1- is wired to bullet tweeter 2+ 2- is wired to a horn.

    my pre amplifier would be connected to amplifier.

    Bullet tweeters on input A

    Horn on Input B.

    Can nx6000d be used to power both these using 1 nl4 cable from outout a or b? 

    I have ran it this way before using another amp but cannot remmeber the make of it.

     

    if the answer is no, how do i get nx6000d to run so input a outputs on A and input B outputs on B.

    I have read the manual but cannot work it out
