    I added another amp and wanted to change my EP2500 to bridge mode operation from stereo.

    It seems like it will not allow me to run it in Bridge mode without enabling the Low frequency filter?

    Is this correct?  I cannot use an EP2500 in bridge mode to power a subwoofer without a low frequency filter?

      DavidKnighton Hello BFAN111,
      No, that is not correct operation of bridge mode. According to the manual, you need only push switch 6 & 7 to the ON position to enable bridge mode. Also note that parallel mode must NOT be active, so switches 4 & 5 must be in the OFF position. The remaining switches/controls for INPUT 1 are optional. The manual does state that the the INPUT 1 options are used specifically for bridge mode operation, meaning INPUT 2 controls are N/A. This statement does not mean that the controls need to be engaged for bridge mode.

    I have had the NX3000 for about 3 years hadn't had an issue at all.  Practiced as normal and the amp started blowing out bright white smoke.  It isn't dust related as it is in a Flight Case.  Still works ,however, I recently purchased the NX4-6000 from Sweetwater Mid July.  Second time being used was yesterday during band rehearsal and it duplicated the exact issue I experienced with the NX3000 and every channel went into Protect Mode.  Fans blew with much more force than normal operating conditions and all I had was 2 Peavy 12" Mains and a Peavey 500w Wedge.  Not nearly enough load to cause this.  Is this a defect or has anyone else ever experienced this issue.

    Is it safe to use pmp 4000 powered amp without speakers connected. I would like to use headphones and do home recording on the pc with tracks adding vocals. Thanks

      WilliamR Hello, Yes, solid-state power amps are safe to use without a speaker load. Only tube-driven amplifiers should not be run without a speaker load.

    I just bought a second hand AMP800 and I've plugged 3.5 to 1/4 cable into the input L & R into the amp with a pair of headphones plugged into the headphone jacks on the front.  

     

    Not only do I not get any sound, I also don't see any of the LEDs on the front moving which is making me think the AMP itself is not working.  I've tried multiple input sources in both input A and input B; same result. 

     

    Any other suggestions before I email the buyer to get a refund on a defective unit?

      ChrisEdwards1 Hi jp182, Are you aware if the unit was supplied with its original power supply or a third-party power supply? If a third-party power supply, I would recommend double-checking all specifications to ensure they match correctly including the polarity.

    Hi there. Just looking for some help. I want to bridge channels A and B and also channels C and D together to effectively create a 2 channel amp (with more power). I have linked channels A & B and reversed the polarity oh channel B then connected to the +1 and +2 terminals of the speakon out for one side, then the same with channels C & D for the other side. Is this the correct way to do it?

    Also - how should I use the gain knobs on the front of the amp when in bridge mode in this way as gain knobs A and B both seem to affect the gain (same for C & D). I hope that I have explained this all ok. I am using the amp to drive 2 x Nexo PS15s in passive mode.

    Thank you for your help. If you have a manual for this amp I'd be very grateful as cannot find one online. 
    Best wishes,

    Toby

      Nigel67 Hi TobyWilson. Well this has certainly perked up a few memories with some of the slightly older colleagues :). It seems as though this amplifier was an obsolete product in 2005, so its doing well. I am afraid that we do not have a manual, but three people have come up with all the answers for you. Its not pretty I am afraid, but better than nothing. Evidently, if you can find one, the 1300C manual was very similar

    Hello!

    Does anyone know how to get in contact with someone regarding repairs for a Behringer power amp? We submitted a ticket (Ticket Number: CAS-480871-P8N9F6), but it was closed and we received no response. Any help would be greatly appreciated.

    Thanks!

      ChrisEdwards1 Hi SFlesch74, upon checking your case I can see one of my colleagues reached out to you on 20/08/2. Could you please double-check your spam and junk folder for their response? We have seen our replies route to this location before.
      If there is nothing in your spam/junk folder could you please let me know and provide an alternative email address? I will then request they reach out again.

    I understand from the manual that the E series 8:2 amplifier enters standby mode after 20 minutes without input signal. Is there a way to disable standby mode? In postproduction studio installations (Dolby Atmos) standby mode proved to be annoying because amplifier channels of individual surround speakers eventually don´t unmute fast enough for single effects ...

      Nigel67 Hi clerc. Unfortunately it is not possible to disable the APO function of the amplifier. The feature is intended to conserve power while the amplifier is idle, and is part of what gives the device an energy star rating. If the feature were able to be defeated, then it would not be energy star compliant.

      clerc Hi Nigel, many thanks for your reply! Are there furtherLab.Gruppen models that enter standby mode automatically with the option to disable it, please? What´s the threshold for the input level to leave standby mode? Is it possible to tally standby mode (i.e. notify the mixer in the control room that some amplifier channels need to "wake up" before playing content)?

      DavidKnighton Hello t3g3lst3n,
      That model is quite legacy. We don't have this information readily available, nor do we divulge service manuals to the general public. I would suggest opening a tech support inquiry so we can help you get it repaired.

      • I blew a capacitor on a LAB 1300, mains side
        t3g3lst3n ok thaks

        i rather mend it my self as only a capacitor, as a retuen for service sounds expensive for a monitor amp.
        ill junk it else as i think it has its eaten so many speaker when it blown a fuse on one power side and sent 40volts DC to speakers over the years. so call it quits with it, last of my lab1300 that was working.
