Hello all ive acquired a es880 echo chamber but havent a scooby doo how to wire it im wanting to connect a pama power mic to the unit and a tristar 747 to the lead all the wires are disconnected on the socket side 1 blue wire 1 black wire 1 white and shield in gray sleeve 1 white and shield in white sleeve the blue and black wires come from the lead that goes to the radio the other wires are connected in the unit any advice will br greatly appreciated
SOURCE: Diesel #8-32 echo power mics
cobra 4 pin is pin1= shield, pin2= mic audio (usually the shield is wrapped around the mic audio wire).pin 3= transmit or push to talk usually red or white whichever isnt wrapped with the shield, and pin4 = receive or speaker complete
5 pin cobra=1-Audio 2- Shield 3-Receive 4-Switching Wire 5-Transmit, you can jump pins 4 and two

ALLways start with ground. Find ground on radio pin with ohm meter. EVERY thing operates off ground. Once you find ground on radio....solder your ground wire on mike cord to corresponding # on mike jack. Once you have ground on proper pin then all else is elementary......use ohm meter to see which wires are TX and RX on mike.....last wire is audio wire.
