      Nigel67 Hi Mikko, I am sorry, but I do not recognise this amplifier. If we do have schematics, then unfortunately we are not permitted to distribute them. There was a LAB 300. Is this what you have?

    It is really hard to get importation organized during the pandemic, we just need one EPQ304 to complete our sound lab build...

    Hi everyone,

    I was wondering if anyone knows how I can track a delivery to Australia of Behringer KM750?

    My music store took my order in November 2020 and then said the unit was not available in Australia and they were awaiting delivery from China which was delayed due to political issues and COVID. Which all sounded reasonable.

    They said it would be delivered by end of December. This then got blown out to end of January. Then Feb etc. Today I got an email saying Behringer now wouldn't give any ETA at all.

    Can anybody help with this? Maybe how to track it down?Has anybody in Australia had a delivery since Novemeber or December come in?

    Thanks for your time.

    I've lost the power supply in my Behringer PPA2000BT. Lights flash, no sound I need to fix this power supply or buy a new one.

    Schematics, sugestions, help?

    Oh boy, where to start. Hi there!


    Okay, a friend gave me a NX3000D to power my passive sub and told me one channel was inoperable. Right now I have it set to "Bridge" mode using a RCA to 1/4" T/S cable from my subwoofer preout to input A on the amp. I'm using a Speakon to bananas connector from output A to my 4 ohm subwoofer, a RBH SV-1212NR, a passive sub. Everything is working.


    My question is about the channel my friend said was inoperable. In stereo mode he said only the B input/output works and there's no signal for the A output (in stereo mode). I have it set on Bridge mode using the A input/output and it's working well. Both green lights above the A and B dials illuminate when I play something. Room correction had me set the gain at about 11 o'clock on the dial. Does this mean I have the amp set to maximize output and have available full rated power, 3000 watts, to my 4 ohm sub? Have I done this correctly?


    Sorry for the rudimentary questions. I'm new to pro amps and still a little confused with the menus. Plus my friend added to my confusion telling me about the inoperable channel when in stereo mode.

      Paul_Vannatto If the one channel is not working, you will only get the power output of the other channel, even in bridge mode.

    Hi there, first post here.

    I have a Lab Gruppen C20:8x and am getting no output from channel F. The CPL fault LED is constantly illuminated (orange) for that channel, also the VHF fault LED. This is irrespective of whether inputs/outputs are connected or not.

    Can anyone advise pls? Feel free to ask for further info. Thanks in adv,

    I'm having issues with the firmware update crashing without installning. I have no problem connecting using the NX Edit.exe tool. I've tried to run the program in compatability mode, both windows 8 and 7 but with the same result. Dont know how to proceed. I cant really find any information regarding how to firmware update.
