pete.young Posted September 27, 2011 Share Posted September 27, 2011 Does anyone have a detailed set of instructions for switching a Markbass LMII from parallel to series? I understand it involves moving 2 jumpers and its probably obvious, but better safe than sorry. Would I be right in thinking that if I change it over to series and don't have anything in the loop I'll need to connect the send and return with a short jack-jack lead?

xgsjx Posted September 27, 2011 Share Posted September 27, 2011 if you take the lid off, there's 2 jumpers. One near the back of the amp & one kind of middle right. One's for Pre/Post EQ & the other is for Parallel/Series FX loop. I'm sure they;re labelled inside. Quote Link to comment Share on other sites More sharing options...

dave_bass5 Posted September 28, 2011 Share Posted September 28, 2011 This should help. Its got both DI and FX loop. Quote Link to comment Share on other sites More sharing options...
Monckyman Posted September 29, 2011 Share Posted September 29, 2011 I can`t see the benefit in de-normalising the loop, can anyone tell me? Quote Link to comment Share on other sites More sharing options...
dave_bass5 Posted September 29, 2011 Share Posted September 29, 2011 While ive never done it as i dont use effects i imagine its to get more control over the tone. At the default setting you get the clean tone and the effected tone coming out of the speaker. I would imagine some people wont want the clean tone in the mix so changing the jumper will remove that. You would then get out what you put in. Thats how i see it anyway. Quote Link to comment Share on other sites More sharing options...
xgsjx Posted September 29, 2011 Share Posted September 29, 2011 I tried it a couple of years ago. Like Dave says, one allows you to have a blend of wet & dry & the other is 100% wet through the fx loop. I've never used teh fx loop since & just run bass > pedal board > amp input.

pete.young Posted October 1, 2011 Author Share Posted October 1, 2011 Thanks everyone for the great information and apologies for the slow reply, I've been a bit busy over the last couple of days. Monckyman, the reason for wanting to do this is to emulate 51m0n's setup with head and compressor in the same rack case - it makes sense to compress all the signal all of the time. First I need to find a rack case (a minor detail!) Quote Link to comment Share on other sites More sharing options...
Monckyman Posted October 2, 2011 Share Posted October 2, 2011 Ta for the info, I didn`t realise it was a half normalled connection. I thought it was a fully normalised connection that completely interrupted the signal path when a jack was inserted in either socket like a patchbay. Might explain why I`m not getting full benefit of my BDDI when I stick it in the loop. I`ll go inline from now on. Thanks MM Quote Link to comment Share on other sites More sharing options...
