    I have 4 of these amps. At last gig in February 2020 (pre-pandemic), one amp developed this problem (fan not switching off). Disconnecting and re-connecting mains appeared to resolve the problem. Amp not used untill testing last week and now problem constant (one fan on whilst on standby, 2 fans on when switched on).

    Identified fault as DSP module on input/output ADIC-01Ac board by substitution from another amp. Before being stung £250 for a complete ADIC board and module I would like to know if there is some sort of engineering setting to set/reset fan function (there was on my old Crown amps). I am advised from UK service agent they do not repair these  boards/modules, only replace them. They also do not supply DSP modules separately.

    As an aside, all mains filter capacitors replaced, 47nf and 1nf, due to most having gone short or partial short circuit.

    Any advice gratefully received.

      DavidKnighton Hello Parky58,
      Your IPD2400 should have a 10 year warranty. I recommend you simply request warranty service on the item and send it off for repair. All costs for parts and labor 'should' be covered if you purchased the item directly from an authorized seller. As for the issue itself, probably a switching IC or transistor has shorted and is allowing current to flow to the fan module constantly. Could also be a thermistor that has malfunctioned and is causing an improper temperature reading to adjacent circuitry, forcing the circuitry to supply current constantly to the fan module. There are quite a few possibilities here, and it's usually more cost effective to replace the affected board rather than spend countless hours troubleshooting.

    Hello! I'm running a PLM 10000Q amp for mains with PLM 14000 amps for subs (linked input from the main amp). The subs are arranged as a center cluster, a delayed horizontal array. Question is, how should I get a mono input feed into the sub amps? I know that  I could get a separate mono output from mixer/stagebox into the sub amps, but can I do it somehow without this routing? Or can the summing be done in the DSP (Lake Controller) somehow? Any help would be appreciated, thanks!

      DavidKnighton Hello leimum79,
      Using the Lake Controller software, go to MODULES > I/O CONFIG and click on the input mixer. Here you can unmute both analog inputs and raise the respective faders to unity. This will essentially sum a L/R signal going into the module.

    Hello Guys I have some questions for you

    Under what circumstances will the PLM+ series amplifier enter the safe mode?

      Hi Vvish, safe mode will usually be caused by an interrupted firmware update, putting the amp in what looks like a permanent standby state. This can be resolved with a safe mode firmware update. You can find a video on the process here: https://www.youtube.com/watch?v=BW-FRGEZcYg&list=PLsbzWq1xgpk9TMlBzSk2pNItJ92oOik_q&index=4&ab_channel=Lab.gruppenKnowledgeBase

        vvish My PLM power amplifier device has been updated, but the device suddenly enters Safe mode after being switched on and off several times, and this has happened 3 times.I want to know how to avoid this situation or where the machine is malfunctioning

    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.

    I find it strange lab don't offer patch panels for their amps... I use the PLM stuff exclusively and there's nothing better than a nicely labelled, perfectly made patch panel. 

    I'm a lab dealer, so yes I would buy one if they made one. Since they don't, I looked for an alternative. For anybody else that may find themselves looking, I give you one suggestion. It's a good one.

    Click this link and see  what I think to be a brilliant artist's work:

    Check out PP+

    For those too scared to click the link, google PP+ Patch Panels.

    No, I don't own the company. No, I'm not getting anything from them for posting this.

    It's a simple heads up that there is somebody making affordable and absolutely perfectly built patch panels specifcally designed for purpose. 

    I bought some. Gonna buy some more. You should too. 

    Music Tribe/Lab guys - throw this guy a bone and swing some work his way. He's not your competition, you don't make the products he does. There are plenty of your customers looking for these things and it's in your best interest to help them out. Steer them his way.

    Maybe a gentle suggestion/push/shove.

      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?

      • May 14, 2021
      • 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.
