    Hi There

    I am fairly new to the entire topic. I bought two Behringer A800 Amplifier with the idea in mind to power my two passive speakers. One I thought to use for the left and another one for the right speaker. My Question now is: How can I set up the A800 in bridged mono mode? Do I simply use Output A, leave Output B empty and use input A for either right or left? I am aware of the bridge mono switch. 

    I am also a bit stuck on the cables as I read that I have to switch one end of the speakon cable from 1+ to 2+ and 1- to 2-. Sadly I can find nothing on this in the instructions manual.

    I am thankful for any input that might help.

    Cheers!

      DavidKnighton Hi James Smith,
      If you focus on the rear of the amp, it is actually very clear how to connect the bridge outputs. Simply take the positive terminal of channel A and channel B, flip the unit into bridge mode, power cycle the unit, and plug your input into channel A. It also tells you that channel A positive is bridge positive, and channel B positive is Bridge negative. If you intend to use the speakon outputs, the silkscreen says to use channel B pins 1+/1-. If you're not sure what this means; almost every speakon has 4 terminals inside. A single amp channel only needs two, pin 1+/1- and pin 2+/2-. You'll need to ensure your NL4 speakon cable is properly wired for bridge operation on this amp by removing the connector sleeve and inpspecting the lead wires. Most speakons will be wired 1+/1- if they are 2 conductor cable.

      Paul_Vannatto Hi James, if you are planning on connecting 2 passive speakers to the A800, you shouldn't change the amp to bridge mode. The reason is that the minimum impedance for bridge mode is 8 ohm. Most passive speakers are typically 8 ohm impedance. If you daisy chain the 2 speakers, the amp will see 4 ohms, which it is not designed to power.

      If you intend to power only one speaker, then you would wire the speakon end (plugged into the A jack) with + on 1+ and - on 2+.

      blazingfirefly Thanks for both your input!
      However, I am a bit confused now. I intend to use Speakon cables as output and I only intend to power one speaker with one amp. No daisy chaining. Paul Vannatos comment seems to contradict what David Knighton wrote regarding the wiring of Speakon outputs to the speakers. David also mentions to use channel B and Paul is telling me to use A. What is correct now? Can I use standard wiring 1+/1- or do I have to change the output wire - from 1- to 2+?

      As in these instructions? (change the output wire)
      https://www.crownaudio.com/zh/site_elements/stb-gen-speakon-bridge-configuration-0001

      Or as in the screenshot attached from the back of the A800 (use standard wiring 1+/1-)

      FYI: I currently have a two conductor cable (two wires) wired to 1+/1-.

        DavidKnighton Hi James Smith,
        Many amps on the market would in fact utilize pin 1+/2+ for bridge operation, but not this amp specifically. So while Paul is correct in a sense, I don't believe he is correct regarding this particular amp.

        EDIT: I retract my statement a bit. Paul is not wrong. I believe you can indeed rewire the speakon for 1+/2+ but only for speakon A output in bridge mode. Speakon B output is wired 1+/1- specifically for bridge mode operation so that you don't need to rewire the cable.

      • Behringer A800 Bridged Mono Mode setup
        Paul_Vannatto Hi David, I definitely don't read the silkscreen that the bridge mode uses the B speakon jack. The top block shows that the 1+/1- is used on the A jack when using it in stereo mode. The bottom block shows the 1+/1- is used on the B jack also when using it in stereo mode. That is the standard for all amps that I've ever come across. The second section of the top block shows how to use the A jack for the dual side configuration (1+/1- for left, 2+/2- for right), which is also the standard configuration (industry wide). The B jack on this particular amp does not have this dual side configuration. Therefore the bridge mode (1+/2+) will only work using the A jack (also industry standard).

        DavidKnighton Hi Paul, it's possible I'm reading the silk screen incorrectly then. I'm looking at the literature to the side and making a correlation. Between bridge mode and output B. The user guide is not very clear on the subject.

    We are replacing the tried and trusted IPD series of DSP-controlled power amplifiers with a new, improved breed of raw power and ultimate control solutions. This move is part of a general strategic leap forward that will benefit you, starting…. Right now!  

    You probably know the feeling: You are planning some fundamental changes, but the time just never seems to be perfect for actually making the big move. But then something unforeseen happens, and suddenly everything aligns, which causes you to pull the trigger on opening a new chapter in your life. That was exactly what happened to us – both specifically when deciding to discontinue the renowned IPD series of power amps and introduce the IPX series, but also on a higher level, as we decided to turn our Swedish facility into a dedicated research and development power house that will be focusing entirely on what they do better than anyone: Design and develop unparalleled amplification and digital signal processing for the future!

     

    Making the Most of an Unfortunate Situation

    As is often the case, unfortunate events tend to occur in quantity. Obviously, 2020 was an unusual and challenging year on a number of levels. First and foremost, the global Coronavirus pandemic took us all by surprise and caused unfathomable human distress across the globe, yet the acute situation also taught many of us new things such as optimizing our collaboration-on-a-distance skill set.

    Fortunately, when entering 2021 it seemed like there was a good chance that things would gradually begin to move back to normal. However, the combination of the pandemic, natural catastrophes and a fire that had consequences throughout the pro audio industry caused severe supply chain problems and skyrocketing freight rates – not just for us, of course, but generally and globally.

    These were the elements that ‘suddenly aligned’ and gave us confidence that now was the time to make some real changes. Transition phases are always painful to some degree, but they are also necessary, and we felt wholeheartedly that it was absolutely the right thing to do – so why wait?

     

    The IPX Move into The Future

    While the IPX series looks very similar to the IPD series that it is replacing, there are indeed a host of improvements to be found under the hood. For instance, the DSP has been upgraded and is prepared to integrate seamlessly with future audio and control protocols.

    Along with sister companies such as TC Electronic and Midas, we have always been a first mover in terms of adopting new technologies, as well as developing them, and this case is no exception. We consider it as a huge benefit to audio professionals when manufacturers across the board agree on standardization and harmonization in order to make your job easier. Therefore, we are pleased to announce that IPX is your bullet-and-future-proof power amp solution. However, this fundamental change of the DSP design also means that IPX is not backwards compatible with the IPD series.

    Further, while specified at the same power ratings as the IPD series (1,200 W and 2,400 W), the new IPX series is more power efficient, and they deliver more power at lower impedance loads. And last but not least, they have a lighter environmental footprint due to their improved power factor load, making them more efficient in terms of sheer electricity consumption.

     

    The Collaborative Move into The Future

    As already mentioned, 2020 turned out to become a year of remote work optimization. However, since Music Tribe has been a global organization for decades, collaborating across country borders and time zones was definitely far from new to us. Along with other factors that pushed in the same direction, we decided to make the move for Lab Gruppen in 2021, ensuring that the engineering staff in Kungsbacka, Sweden, is now allowed to dedicate its every moment of attention to developing, refining, rethinking, improving and designing new products and cutting-edge technologies that will help you stay ahead of the curve.

    This means that production has started taking place in Asia, which may cause concern to some, but please rest assured that you will not experience any changes in terms of quality, sturdiness and reliability. The number one mistake Western companies make when moving production to Asia is more than anything to have missed out on doing their homework properly – on a cultural as well as a practical level. Well, Music Tribe has been present in the region for ages. In fact, far longer than e.g. Apple and other huge consumer goods manufacturers that we have all accepted as high quality vendors long ago. It cannot be stressed enough that this is not a new process of change for us, or a first attempt at dipping the toes in new waters – we have decades of experience with how to manufacture efficiently and reliably out of Asia. And perhaps most important of all, we have a proven track record of successful Pro Audio and MI brands to back our beliefs that this will indeed become very beneficial for all of our customers.

    At the end of the day, all that really matters is providing the finest audio tools imaginable, which in turn empowers you to focus exclusively on delivering stellar results as an passionate audio professional every single day – regardless of whether your field of work is within Touring, Venues, House of Worship, Corporate, Education, or other parts of the Live Sound and AV Install spheres.

    On the spec sheets it states that the NX6000D has the following modes:  

    • BRIDGE, DUAL (Dual Mono), STEREO, BIAMP1 or BIAMP2.

    I connected to the amp via NXEdit, and the only modes that are being shown is: DUAL (Dual Mono), STEREO, BIAMP1 or BIAMP2.

    I went thru the front display and even there the option for Bridge is not shown.

    So my question, how do I set this amp in Bridge mode?

      john0121 Hi MrGTO, the NX6000D doesn't feature a bridge mode. This is covered in the user manual and no bridge power is specified in the QSG here:

      https://mediadl.musictribe.com/media/sys_master/hc5/h4d/8850167529502.pdf

      Could you let me know the document you have read there is Bridge Mode for the NX6000D in case there is an error?

      • NX6000D Bridge mode???
        MrGTO Hi John, this is a big issue, the link attached above is for the user manual correct? This is a screen shot from that manual... #6: so I ask, how do I access Bridge mode on this $600 amp I just purchased?
        • September 14, 2020
    • MrGTO
      MrGTO This was one of the selling points for the setup I built. Very misleading. Listed as mono bridge being available on the nx6000d on Sweetwater and parts express.
      • September 14, 2020
    • MrGTO
      john0121 Sorry this would seem to be an error in the product description, and I agree it could be made clearer in the QSG that Bridge mode does not apply to the NX6000D. I will report this to the relevant team at once so it can be updated to avoid this error in future. In the meantime it would be best to contact your Sweetwater rep for assistance in sourcing an amp suitable for your setup and returning this one. If you need more help with this then plesae submit a tech support case via the support button and a member of our team in your region will be able to assist.

    Hi everyone, since Behringer studio amplifiers are often used in home HiFi too, someone made an unofficial DIY kit to convert their look:

    A500_hifikit_1.jpg

     

    The main problem - since it's CNC manufactured - is the cost (around 120€)...

    ...it would be great if Behringer release an OFFICIAL "look conversion kit" at a reasonable price (50€ or even less) !

    Let me just lead this off by letting it be known that I'm not particularly versed in the matter of Power Factor Correction. All I understand in the matter is that if an amplifier has none, they wont run well on consumer grade generators... or so I've read. I've also read that the iNuke series amps won't run well on consumer grade generators for this reason (no power factor correction) and that some of the amps take short gulps of large amounts of current (upwards of 80amps). Does anyone know if this is (still) the case with the newer NX series of amplifiers? Will they run okay on consumer grade generators?  Thank you

    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?

      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,

    I bought a couple of iNUKE1000 amplifiers a couple years ago, and their performance has been excellent, especially considering their value, light weight, and low impedance matching. I was planning to buy a few more until I found out that they are all discontinued, and the closest thing that Behringer has are the NX series amps which are heavier and significantly more expensive. Does anyone know why they're discontinued?

    I experienced something similar when I bought a Behringer X32 CORE that retailed for $500 brand new, and then it was discontinued a month later. I wanted to buy more, but by then price has gone up to about $1,500 on eBay for *used* models! And sure enough, I'm starting to see used iNUKE amps being sold at 3rd-party retailers for much higher prices because of the supply vs. demand.

    Is this a trend I should worry about?

      Hi Keith @KeithWeinstein ,


      Yes the NX series has replaced the iNukes. I got the NX3000D model for my church a few months ago and have been very pleased with it. It is quite light IMO (7.9 lbs) - much lighter than the old Peavey amp it replaced. 


       


      For the X32 Core, the replacement is the Midas M32C, which is a tad more expensive, but a lot less than the gouging ebay prices.

    Warranty repair...

    I’ve been trying to contact Behringer for the last week. They used to be a phone number you could call and talk to a human. Now the only way to do it is to get on Music tribe. I’ve had such a hard time trying to get on Music tribe. Does anybody have a solution to how I can go about getting my Behringer app repaired under warranty?

      Hi John ( @Coda2020 ), 


       


      Welcome to the community.  You need to open a warranty repair case here: https://www.behringer.com/brand/behringer/support#googtrans(en|en)


       


      You should receive any automated email reply with a case number telling you that someone will contact you within one business day.  Be patient since that is more like a week (or more) these days.  If you don't get the auto-reply, check you spam or junk folder. 


       


      Hope this helps, 


      Ken
