    Hi gang,

    I have a C10:8x amp that appears to be sending signal crossing over to channels it shouldn't be on (proper signal on B, appears to be bleeding to A sporadically). I have shifted the wiring at the back gently and it appears to have removed the issue but I am wondering if anyone has experienced the internals of the amp malfunctioning to cause bleeding between channels. Would a power cycle of the amp be advised?

    Thanks!

    Currently Behringer power amplifiers power ratings are expressed using the term "max power" and Behringer officially states that "you can expect the RMS/continous power rating would be "around" half the declared max power rating".

    What does "around" half really means? It is "around half" at least or "around half" at most?

    Specifying "Max power" only for a power amplifier could mean that its continous long term power rating may be anywhere over "around half" or under "around half", which makes it difficult to design and calculate a sound system and to choose the proper power amplifier for the loudspeakers for which the continuous and peak power ratings are known.

    What methods or guidelines does Behringer use or follow to determine the power rating of its power amplifiers?

    Are amplifiers tested with sine wave test tones at different frequencies inside the supported bandwidth?

    Are amplifiers tested with pink noise (what crest factor) inside the supported bandwidth?

    Are amplifiers tested with both or all channels driven?

    What is the maximum THD allowed during the power rating procedure?

    What is the resolution of the digital signal processing units used on the power amplifiers with DSP?

    Thank kindly!

    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

    Hi,

    We are using a PMP 6000 Power Amp/Mixer with 2 8ohm Speakers. We want to discard these speakers and run powered speakers from the line out.

    Is it possible to run the PMP 6000 with out speakers attached to the power amp outputs.

    Thanks

    Jez

      WilliamR Yes, you can run powered speakers from the line out of your PMP6000 without the mains hook up.

    PMP1280S Powered Mixer.  Picked up used, but not powering up.  Checked 10A fuse at AC input, is OK.  Suggestions on what to test for?  I could send it to someone to repair, but I at least want to take a shot at this.

    Hi,

    I have problems with CH 4 of this Amplifier. After about 10min Pwr-On-time, on this channel is present a noise (HF). It is also present with mute on. Ch 1-3 are absolute quiet.

    I´m the second owner of this amplifier. Problem is, I do not have the original bill. It was bought in Austria, I´m in Germany.

    Because, this product is actual less than 10 jears on the market,  it may a warranty-case?!

    Can you help me?

    Regards

    Martin

    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
