    Hello,

    I have followed the manual's instructions for setting the power amp in bridge mode (dip switches 4-5 OFF, dip switches 6-7 ON). My signal chain is as follows:

    Bass guitar > Sansamp RBI > Behringer EP2500 > Gallien-Krueger 410SBX Plus (8ohm, 800W RMS)

    I have tried using both the Speakon and 1/4" speaker outputs, but the volume that comes out is very low, even with the output level on both the Sansamp and the Behringer at maximum.

    Any help appreciated.

      Paul_Vannatto The Speakon connector has to connect the speaker wire to the 1+ and 2+ for bridge mode. The default speakon connection is 1+ and 1- (for non-bridge mode). Dismantle the speakon connector and change the wire on 1- to 2+.

    The blue light on the front of the speaker is flashing and no sound comes out.

      Nigel67 Hi dbrigham913. What is the power LED doing on the rear of the speaker? Is this flashing as well? In which position do you have the switch for the front LED? If it is in Lim, try moving it to the Off or On position and see if you get audio from the speaker. Either way, it would appear that the speaker has a fault. Please fill out a Technical Support ticket and include the serial number of the speaker and your proof of purchase (invoice) so we can advise further. 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 Technical Support tab and submit a ticket. Many thanks

    Wondering if the bridge cable i had wired specially for use with my inuke nu-4 6000 will work when bridging the newer nx 3000? I suspect it will work but looking for confirmation...thanks

    I'm struggling to understand the value and intended usage of the The Behringer KXD15's "stereo link" feature. It is described in the quick start literature as allowing one to connect a second KXD15 via a "stereo link" cable. What the literature does not address is what happens to the inputs and mixer section on the "slave" KXD15. 

    1. I am guessing that the inputs on the "slave" would be disabled / unavailable, since there would not be a way to feed its inputs back to the "master" KXD. Or, is the intent is to connect the output from KXD.master to the input of KXD.slave and vice versa, which then raises the question, how does the "system" know which one is "master" vs "slave"?
    2. Assuming my guess is correct, that the slave inputs are defeated when in link mode, aside from the relatively low cost of the KXD series, why would one purchase a second KXD only to lose half of its functionality?
    3. To achieve stereo sound, wouldn't one be better off just purchasing two powered satellite speakers and using the XLR outputs?
    4. Is there another mono combo amp (amp+speaker only) that would pair with the KXD for equivalent sound quality that one should consider besides a fully-loaded KXD, or TWO satellite speakers?

      PedroRodrigues Hi TheRealAndlBequet, thank you for your post, you are correct on all your analysis and effectively this is how the KXD15 stereo link operates. The stereo link will only operate correctly when using two KXD15. When it comes to the options you propose that might work, in the end of the day this is all conditioned by your user requirements and the tools you need to have available. Thank you

      CLCarter 1: I have had to increase the gain on my cassette deck to get a reasonable recording. Is this normal? I have temporarily routed the cassette deck to the main output.

      CLCarter 4. I want to make sure that that I have the inputs and outputs in the right place. The inputs for the 4 channels are set. It is just the outputs that I am not sure about.

    Good evening - I have had an amp out for repair LG FP14K with Panurgy for a few months, and they are quoting 3-4mos for a psu replacement - I wanted to find out specifically what the status is as the message from them has been consistent since March with no imporovement on the timeline, let me know if this is the incorrect forum for this question, thanks.

    Will a Behringer A800 work off a passive pre amp such as the NVA p50sa passive pre amp

     

    Thanks

      djtetei NVA P50 SA will work with Behringer A800 amplifier, but you have to carefully select the input sensitivity and watch the output level from the preamplifier, in order to avoid clipping. Personally, I would suggest using a high quality mixer, with gain control on all inputs, balanced outputs and accurate level meters, between the source / preamplifier and amplifier. Also, take note of the fact that Behringer amplifiers rated power output is published as peak and you can expect the RMS / average power output into the given load to be about half the peak power rating. For Behringer A800 the average power output into 8 ohm load will be 2x110 W / channel and the average power output into 4 ohm load will be 2x200 W / channel. To ensure a 3db headroom between the speakers rated continous power and amplifier continous power, you can use speakers rated to 50W into 8 ohm or 100W into 4 ohm. If your speakers rated continous power is higher than above values, you can run the amplifier at its limits, with no headroom at all or you can look for a more powerful amplifier.

    My inuke stopped working. Starts to fire up but then fan shuts down after a few seconds and all the channels have the red circles. They dont turn orange. Is there a fix or is this amp toast?

    Thanks

    Matt.

      djtetei Disconnect the speakers and try to power on the amplifier without any load. If the described symptoms still persists, you may have to open the amplifier for service.

      StaffordAV Hi Matt,
      I have an nu6000dsp with the same problem. It turns on and all the dps functions work, but the rings stay red and there is no output.
      I’ve had a quick look at it, and the main ht rails to the amplifier seem to be controlled by a KA3525A switch mode controller. Having checked the data sheet, this has a shutdown facility (pin 10), which should be pulled low to turn on the output. Mine measures at about 4.5 volts, which might be causing the lack of ht voltage. All the other voltage rails are working OK.
      When I get some time I’ll disconnect pin 10 on this ic and tie it to ground with a resistor, and see if I get power to the amplifier; which will then determine the next course of action.
      Not knowing your background, or whether you have any experience at electronic repairs, I can’t recommend just poking around inside the amp, but it is something for you or your friendly tech to look at.

      My Tech guy said these can't be repaired he said not even by behringer. Little to no support and that they were designed to last 5 to 10 years and I should basically just throw it in the garbage...

      StaffordAV If you can get replacement parts, or their equivalents, pretty much anything can be repaired. Whether it makes economic sense is a different matter; probably not for Behringer.

      Regarding the red rings of death. I have now had a chance to look at this a bit more closely. The first step was to remove the KA3525 controller (IC3), and replace it with a socket, which would make experimenting easier. That done I put in a SG3525, which is an equivalent ic. Turned on and it worked; temporarily. Having fitted it into a socket let me easily disconnect pin 10, the shutdown pin, after which the amplifier worked OK. However, as this probably disables all the protection circuitry, not really a satisfactory repair.

      Back in a working state, I was able to test for correct voltages around the circuit. The shutdown voltage is provided by IC2, a 555 timer, whose reset pin is connected to ground through a transistor (T4). When the base of the transistor is low (mVs) the output of the 555 is high (3.5V) and the amp shuts down. When it is working there should be about 4.5 volts on the base of T4. On my amp the voltage here was low, so the output of the 555 high, causing the amp to stay in protect mode.

      The problem turned out to be a transistor (T9), which when the amplifier is turned off pulls the control voltage low enough to trigger a shutdown. Removing this transistor let the amplifier power up properly, but it wouldn’t turn off. T9 is a surface mount npn transistor, which I have replaced, and the amplifier now seems to be working correctly.

      I’m not sure if the original KA3525 ic was faulty, but the total cost of replacement parts was less than £1UK so replacing it was not really an issue.

      I don’t know if this is a common cause of the amplifier being stuck in protect mode, but removing T9 can be done without taking out the psu board, so is an easy first thing to try. Before doing anything else, measure the voltage across C24; it should be about 4.5V on a functioning amplifier.

      The base of T4 can also be pulled low by T2 a thyristor, which is triggered by DC offset voltage on the amplifier output. It is connected to the main amplifier board through an opto isolator; so something else to check if T9 is not the problem. Obviously check that there is no DC on the output and the protection circuit is working properly.
