Postby D.J.FAWX » Sat May 02, 2020 7:57 am

Hello I have just aquried a folder PA speaker system....and I'm having trouble finding the right amps/configuration to drive it....
There are two sonico sm 15/NS
And two MTX 15 somethings.....
All four have TS Jack's wich are not labeled in/out nor plus or minus.....I cant find anything really on the specs or set up of these.....any help would be appreciated on hooking them up both in parallel and series....

Well, the 1/4 “ jacks are more than likely just wired in parallel. You can see if the speakers even work by putting in a cable and briefly put a small battery on it to see if they “ click.” I often use a 9 volt.
