    Shut down of Lab Gruppen Amplifier with Contact Closure | Power Amplifiers

    Do any of the Lab Gruppen amplifiers support shut down of the amplifier upon receiving a contact closure?

    Application is to prevent conflict with life safety systems, directly at the amplifier.

    Please also advise if there is a different way to seek this information more effectively.

    Kind Regards

      Hi @jboehme 


       


      Could you confirm which software you are reffering to? Do you mean the device control software used to monitor C and FP series amplifiers?



      Thanks,

    IPD 2400 Firmware Update | Power Amplifiers

    Hello, we have a problem with an IPD2400 and the firmware update. With one of our IPD 2400, the update collapsed in the middle of the erase. now the IPD no longer starts. What can you do? Thanks! Harald

      Dear Harald,


      Hope you are well.


      Are you able to confirm if the device is still receiving power fine, however, is just stuck in Standby? Or will the device not power to Standby?


      Thanks in advance.

    where to get spare parts for PLM Series | Power Amplifiers

    is there any other way to get spare parts of the PLM series 
    bequase every time we if send it to repair and they have this Absurd high repair costs
     we can also do it ourselfs   its not that hard   its more hard to find the problem  
    but with 7 plm's in total  we rather want to do it ourselfs

      Hi Sowatt,


      You can contact our CARE team and ask but I would warn you that performing these repairs yourself will void your warranty. Also, our service centers have specialised repair and testing equipment which is quite essential to perform a quality and most importantly, safe, repair.


      Not trying to downplay your skills as a repair engineer, just a bit of insight into what goes into the process of service.


      Honestly I would very strongly reccomend you send your amps for repair in a certified service center, if you are getting repeat failures then its worth doing some analysis as to the cause also. It may be that you can avoid having to send it in to start with.


       


      I am more than happy to advise and assist further...

    IPD2400 does not turn on - DSP | Power Amplifiers

    Hi,

    A year ago I bought two Lab Gruppen IPD2400.
    After a few uses, now one of them does not turn on.

    When I plug it to AC, it does not go to stand by mode. And does not turn on.
    Fan runs, ethernet socket shows activity lights blinking, and Intellidrive Controller can connect with a valid IP address, but does not synchronize. 

    Seems that DSP is not working.

    Anyone has experienced something similar? Any ideas?

    Very frustrating. After investing money on top class brand amps, it only lasted a year.

     

    Regards

      Hello


      Same problem here with a new ipd2400 at first start-up.


      No stand-by mode , black display , but fans at full speed. After 1 hr I cut the power en reconnect the power cord. The amp starts normal.

    IPD amp DSP app - is there a way to copy & paste settings between channels? | Power Amplifiers

    Well this is a busy forum isn't it?  Does anyone know of a way to copy and paste DSP parameters such as EQ and limiters between channels on the IPD control app?  I'm using the Mac and iPad versions and don't see this option.  Is it available perhaps in the Windows version?  

    Is there a better forum for this sort of question?  This one seems fairly low traffic.

      Hi @RileyCasey,


      My apologies for the late reply here.


       


      There is not a direct copy and paste feature but if you are trying to achieve matched channels, a stereo pair of speakers for example, then you can link channels and everything programmed on channel one will be copied onto channel 2 (with shared control for both channels).


       


      There are two link options found on the "Levels" tab, one for input stage and one for output stage. See attached picture.

    PDX3000 | Power Amplifiers

    Hi,

     

    I am new here. I would like to ask some technical question about new Lab Gruppen PDX3000 amp. It seems to be a perfect solution for my JBL4645Cs. First of all I would like to know what is the DAMPING FACTOR (aprox. up to 300Hz)?. For the input on XLRs I would like to connect it directly from the integrated amplifier from speaker terminal (high level to low level); I made some measurements and normally high level does not exceed 0,5V - how much volts can take XLR input on PDX3000?

     

    Thank you very much in advance.

     

    Kind regards,

     

    Gasper Jancigaj

      Hi Gasper,


       


      The following is a white paper published by Lab.gruppen detailing why we do not use Damping Factor in our specifications.


       


      Damping factor


      The damping factor is determined by the quotient of the speaker impedance and the output impedanceof the amplifier. To state the damping factor figure of an amplifier is meaningless, as the speakerimpedance’s varies with the frequency and the various types and brands of loudspeakers existing.The figures of the true damping factor are only valid for a specific amplifier/ loudspeakercombination. This fact gives one of the reasons why Lab.gruppen don’t publishes the damping factorfigures.The only figures that are relevant for amplifiers are the output Impedance figures. Most amplifiers onthe market only show low output impedance (or high damping factor) at low frequencies and high(er)at high frequencies. This is due to the improper design of the output network and/or frequencydependent feedback. Lab.gruppen design has the feature to have nearly constant impedance over theaudio frequency band with a value of 0.05 to 0.07 ohms (50-70 mohms) . This causes less coloration.Another feature of the power supply in the fP 2200 - fP 6400 (thanks to the stabilised power supply),is that the output impedance doesn't rise during clip situations. In most conventional amplifiers theimpedance rise 10 or l00 times during clip. That causes uncontrolled movements of the speaker-cone.The conclusion must be that the Lab.gruppen switch mode power supplies sound better or have betterdefinition, especially in the bass region, compared to conventional designs.


       


      Damping factor influences on active and passive frequency divided loudspeakers


      Another reason not to publish the damping factor is that it’s not relevant to the audio quality of the power amplifier. For example; a professional loudspeaker driver has a DC-resistance between 2 and 5ohms, which is connected in series with the driver in the equivalent circuit diagram of the driver. Inthis case, the damping factor has more to do with the speaker itself than the amplifier, as the speakerdriver is connected directly to the power amplifier just as in an actively divided system (see example below).In a passively divided speaker system the filter network circuit are placed between the power amplifierand the speaker driver. In this case, however, the filter impedance determines the damping factor ofthe speaker driver. The output impedance of the power amplifier can influence the characteristics ofthe filter response, but it’s not sure that a lower impedance (higher damping factor of the poweramplifier) will give a better response. A classical example is the tube amplifier, which has relativelyhigh output impedance and which gives a very good sonic result in most cases.


       


       


       


       


      I am not entirely sure I understand your question,  "For the input on XLRs I would like to connect it directly from the integrated amplifier from speaker terminal". Could you explain what you wish to do in a bit more detail please?


       


      The PDX inputs are Line Level, if you are using an appropriate audio source then it will be a line level output also. What are you planning on using to drive the input on the amplifier?
