Re: Amp kicks out on Mic ONLY with 8 ohm to 70 V Xfmr on Amp outputThat differential connection of the 70V transformer makes it act like a surround speaker, not a center speaker. If every source is mono, and is only connected to either a left input or a right input (but not both), it will sum as you expect. Any chance the mic's output is connected via y-cable to both left and right inputs? That would cause significant cancellation of the mic's signal at the transformer.Jim Thorn
