Re: 8PAKAMP & 12PAKAMP KIT BUILD THREAD

Hey there, I am really happy with my 12PAKAMP, powering a pair of LXmini+. The woofers and subs are powered by a pair of bridged amp channels each and the tweeters by a single channel each. It is powered by an 18 V transformer. The amp is running quite a while now, but I finally put it into a nice c...

Re: 8PAKAMP & 12PAKAMP KIT BUILD THREAD

HI Niklas I will be back from AES New York around the 23rd October so I can work this out for you then. IN the mean time with the amp off measure the trimpot ohms between the outside legs of each pot and post here so I can work out the ideal setup. Hi Joe, that would be nice, thank you! Yeah, I've ...

Re: 8PAKAMP & 12PAKAMP KIT BUILD THREAD

Hi Joe, the Amp is running. :D After having some stability issues with the tweeten channels the amp is running fine now. The problem occured when no Input was connected in my non balanced setup. But I found a solution in this thread. The problem was, that I’ve connected In- and GND to the RCA Gnd. I...

Re: 8PAKAMP & 12PAKAMP KIT BUILD THREAD

Hi Joe,

wow, thats a cool feature. But I also dont think I need it. Even if I need to use some fans, I would probably let them run at low speed the whole time and it would make a bog difference.

Thanks for the great support

Re: 8PAKAMP & 12PAKAMP KIT BUILD THREAD

Hi,

just because I am curious: What is the use of the diodes and the two fan parts when fitted as intended?

Greetings

Niklas

Re: 8PAKAMP & 12PAKAMP KIT BUILD THREAD

Hi Joe, thanks a lot for the quick and detailed answer! In Germany we say something like: A picture tells more than a thousand words. :) The muting is much easier than I thought. Cool! I have already bought a 2x18V Trafo and the bridge rectifier, because it was mentioned earlier in this thread. I wi...

Re: 8PAKAMP KIT BUILD THREAD

Hey there, I just recieved my 12PAKAMP Kit (blue) and I am going to use it to power a pair of LXmini + Subs. The PCB looks pretty good. For the Sub (8Ohm) and the Bass (8Ohm) units I want to use 2 channels bridged for each driver and for the tweeters (4Ohm) one channel per driver. But I have some qu...
