    Can you repair this piece or does the customer need to purchase a new device?

    Greetings! Is IT possible to use Lab.level4 volume Control with C20:8X Amplifiers? Thanks for the reply! Miha

      AlexLane Frame reset


      A factory reset and soft reset can be performed from the front panel. A factory reset will restore all settings to
      original defaults, including network settings, frame presets and current settings. A soft reset reverts only the current
      settings to default. Network settings and frame presets are not changed with a soft reset.


      1. Place the frame in standby mode.

      2. Press and hold elect and channel 3 mute button. Then press the power button.

      3. Choose from one of the below operations:

      a. Press channel 1 mute button (red LED) to initiate the factory reset sequence.

      b. Press channel 2 mute button (amber LED) to initiate the soft reset sequence.

      c. To cancel, press channel 4 mute button (green LED).

      4. Wait state indication is present while either reset is performed.

      5. To complete the factory reset process, cycle the mains power by completely removing the power plug and
      reinserting it.

    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.

    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 and good morning,


      Yes, the following Lab.gruppen amplifiers have this feature.

    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,

      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?

    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...
