Pete Academy Posted August 16, 2012 Share Posted August 16, 2012 Has anyone had issues with the amp cutting out when the blue clip light comes on? Quote Link to comment Share on other sites More sharing options...
Raggy Posted August 16, 2012 Share Posted August 16, 2012 No, have never had that, and I push my amps hard. Quote Link to comment Share on other sites More sharing options...
Gareth Hughes Posted August 16, 2012 Share Posted August 16, 2012 I have an LMK head and only ever had the issue of the power amp cutting out when it either overheated in it's rack case or had dodgy power from the venue - I suspect it was the latter. Interesting thing was that the preamp and DI sections were unaffected and thankfully I was playing in a band with a decent monitor system that night.

xgsjx Posted August 16, 2012 Share Posted August 16, 2012 I'd get in touch with the shop you bought it from as it sounds like a fault. The manual for the LMII says play to clip & then turn back slightly so it only clips on loud notes. Quote Link to comment Share on other sites More sharing options...
nottswarwick Posted August 16, 2012 Share Posted August 16, 2012 The 2 I owned were faultless and I used to gig at volume regularly. Quote Link to comment Share on other sites More sharing options...
M@23 Posted August 16, 2012 Share Posted August 16, 2012 I've not had this issue. Only run about 50% gain. where abouts do you run this gain? Quote Link to comment Share on other sites More sharing options...
Pete Academy Posted August 16, 2012 Author Share Posted August 16, 2012 I'm careful to run the amp below the clip. However, there have been the odd times I've accidentally gone into clip, and the amp has cut out. Weird. I don't understand how other players have got away with it.

HazBeen Posted August 16, 2012 Share Posted August 16, 2012 I have the LM800, which has the same pre. Never any issues either.... Sounds like a dodgy circuit somewhere.... Quote Link to comment Share on other sites More sharing options...
Pete Academy Posted August 16, 2012 Author Share Posted August 16, 2012 Thanks folks...looks like a definite fault. Quote Link to comment Share on other sites More sharing options...
andyonbass Posted August 16, 2012 Share Posted August 16, 2012 Where did you get it from? If it was Thomann, have a look at this email I got sent from a company over here which offered a price matching service. They couldn't get anywhere near the Thomann price but sent me this. I dont know whether its a ploy to scare people away from Thomann or if there is something in it [Quote]Hi Andy, details are as follows: Markbass write clearly on their website and in the user manuals the following information. (this is taken directly from the product page for the Little Mark III Head). “Markbass amps/combos are manufactured to be sold and used in the country of purchase, and they are factory preset to that country’s voltage. Due to homologation issues, the voltage may not be changed.” What does this means in practice? 1. Markbass amplifiers are designed for the country they are sold in. For Europe the voltage in the UK and EU (Germany/France) is slightly different. Markbass does make different models for UK and EU zone, and these can be tracked by serial number. 1. If a customer uses a lower voltage EU model in the UK, there is a risk, the amp can suffer a power failure. These failures cannot be treated as warranty repairs as there is a clear notice in the user manual warning not to use them outside of country of supply. Also, depending on the nature of the damage, the amp will have to be returned to the country of origin for service – most likely by the customer in consultation with the supplying dealer. 1. Markbass will not supply us or our UK service agents with parts for amps that are not UK electronic spec. (Clearly for power safety reasons) . 1. This does mean that amps bought from European mainland dealers should not be used in the UK, and if they suffer a power failure will have to be returned to the shop from where it was purchased to be serviced. 1. If you are wondering about musicians who come to the UK with their Markbass equipment. We have procedures in place for touring artists. Please contact us if you get a call about this from someone.

fretmeister Posted August 17, 2012 Share Posted August 17, 2012 Sounds like selling scare tactics. UK Voltage is a nominal 230V (as is Europe) but in reality can shift from 220 to almost 250. Quote Link to comment Share on other sites More sharing options...

Pete Academy Posted August 17, 2012 Author Share Posted August 17, 2012 I've brought my amp into the shop today and tried it plugged into a New York 804 cab. I set the input gain high and twatted the strings, especially the low B, causing the blue clip light to come on constantly. The amp never cut out. I'm totally confused. Live I use 2 x New York 604 cabs. I use Monster speaker cables and a Monster bass guitar cable. Any suggestions? Quote Link to comment Share on other sites More sharing options...
yorks5stringer Posted August 17, 2012 Share Posted August 17, 2012 Yes, I got sold that line to when I bought my LMII 4 years ago from mainland Europe and its never missed a beat. The voltage thing is a red herring, as someone else has said, our voltage here can vary considerably. Its even possible to convert a US 110V MB to UK voltage by just moving some wires so i don't think the voltage regulator ( for want of a more technical term) is market unique. Re the cutting out, I think its a known issue, I remember a huge thread on Talkbass some years ago when MB first hit the US Quote Link to comment Share on other sites More sharing options...
Pete Academy Posted August 17, 2012 Author Share Posted August 17, 2012 Just another thought. When I connect my two cabs, I use the speakon output for one cab and the jack out for the other. Is this OK to do? Quote Link to comment Share on other sites More sharing options...
spike Posted August 17, 2012 Share Posted August 17, 2012 I remember reading something about this on Talkbass and if I remember correctly it was something to do with using two cabs and the overall impedance being less than 4 ohms. Even though the nominal impedance of each cab might be 8 ohms, if it is slightly less ( say 7.5 ohms ) this can cause this problem. Hopefully someone who knows more about this stuff than I do can confirm or deny this. Quote Link to comment Share on other sites More sharing options...

nottswarwick Posted August 17, 2012 Share Posted August 17, 2012 I think I would be double checking the wiring in my speaker leads - could be that a stray loose wire is causing one of the leads to short out, maybe under vibration - a long shot, but it would cause issues Quote Link to comment Share on other sites More sharing options...

[/quote] Should not be the issue since they are wired in parallel, it could well be a faulty speaker lead though as already suggested.
