Hi, We have this mixer/amp since long ago. We recently upgraded and want to reuse it elsewhere in our setup (place of worship) but can't find any specs or manuals online or elsewhere to set it up properly. Mainly need to know impedance. Has anyone come across this or knows this company's website? https://ibb.co/ca3itw https://ibb.co/kAUdRG https://ibb.co/gyEOtw https://ibb.co/haawDw
