    Hello, i have a plm20000q, dual module apmplifier and i have 8 adamson s10 cabins... i wanted to know how must i configure my plm20000q through the lake processor to be able to use both channels of my amp to reproduce full L/R stereo using both modules of my amp... when im recalling the adamson presets on my lake processor it allways collegates my A channel with my B channel. any one can help me?

    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

    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)?

    I blew a capacitor on a LAB 1300, on mains side, where do i find the correct spare, as only legs left...

    I had it since late 80s so quite old, it have eaten many speakers over the years ;)

      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.

        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.

    Is there any way to escalate to Lab Gruppen. We have been waiting since January for a client's repair on a Lab Gruppen E5:4 amplifier. We keep getting told the parts are on back order.

    Good morning, I was wondering if it was possible to convert an older LGFP14K from US mains to EU mains? If so, what would that entail?

      DavidKnighton Hello hiswkf,
      Check the voltage spec on the rear panel near the mains input. If it does not specify operation up to 230V, then I would say not possible, at least not without some involved modifications.

      DavidKnighton Hello Djgatos,
      The SA cabinets are 16 Ohm and require about 1,200 watts per cabinet. By running multiple boxes in parallel, you could get 4 cabinets down to a 4 Ohm load, however the power requirements for that many speakers would far exceed the PD3000 power output. You would need an amplifier that could achieve 5,000 Watts @ 4 Ohms so it could properly handle the peaks. The PD3000 produces 1,500 watts per channel, and does not appear to be a bridgeable amplifier, so 1,500 watts is your absolute maximum output @ 4 Ohms. The amp that I would recommend would be the PLM12K44, which can deliver 3,000 Watts per channel at 4 Ohms, or you could bridge for effectively double the output power, which is what I would suggest for these speakers. You would need a single PLM12K44 amplifier to adequately power all 8 boxes in a standard stereo L/R configuration. Not including the subs mind you.

      My Sa audio cabinets I switched the wire to 4ohms each cabinet you think 1 amp can handle 2 boxes 1 each side?

      • Pd3000 lab gruppen power amp
        DavidKnighton At 4 Ohms, the amplifier will deliver up to 1,500 Watts per channel. If you chain two cabinets at 4 Ohms each, your load ends up being 2 Ohms on the amp, which ends up producing less watt output, about 1,000 Watts. I would recommend. In this case I would suggest 1 amp channel per box, which means you'd end up running quite a bit of cabling. I'm not sure how the power requirements change as you switch the cabinet to 4 Ohm load. Maybe you can switch it to an 8 Ohm load, I think that would be better, because then you could chain 2 cabinets for a 4 Ohm load. The amp will perform the best at 4 Ohm loads.
