Sir mere paas ye controller hai office mai, but eska ye emergency microphone ka wire connector se Tut Gaya hai, and now don't know the color code to solder it back
Bosch booster amplifiers are balanced ones, where balanced line out (+ G -)from Evacpro-G2 should be connected with line input (3-pin XLR) of amplifier, also 0,100 unbalanced output from amplifier should be connected to a Evacpro-G2 input (screw terminal- Red&Black)
