Hello
I’ve just picked up a zmacs and I am seeking some help. Zmacs works with just one out of three amps, it won’t pass the guitar in signal to the two tiny marshall 50th heads.
Marshall jvm 1, 16 ohm or 8 ohm amp 3
Marshall jmp 1, 16 ohm amp 2
Vox ac15, 16 ohm amp1
Power station 50 watt in top attenuator spot
All 3 cabinets work with the vox.
Both marshalls work with all 3 cabinets and the power station only the guitar is plugged directly into them so the issue seems related to passing the input.
The power station correctly attenuates or amplifies all three amps.
I’ve also tried sending input from amps 4 to a combo and that works as expected- sound on the combo but none of the cabinets.
