How to Take Apart the Electro-Voice RE20 Microphone
By Matt McKay
Taking apart the Electro-Voice RE20 microphone is sometimes necessary to access internal wiring and components for maintenance and repair. Used in many professional broadcast and recording studios for its rugged build quality, mistreatment and exposure to environmental extremes can cause wiring and internal parts to fail. The EV RE20 is tightly engineered, so good quality tools are a must for successful dismantling.
Taking Apart the RE20 Bottom Section
Step 1
Locate the set screw on the side of the microphone connector housing and insert a small screwdriver.
Step 2
Turn the screw counterclockwise to set the screw fully into the connector. The screw is reverse threaded and cannot be removed externally.
Step 3
Grasp one of the connector pins gently and pull the connector housing from the microphone until the soldered connector wires are visible.
Step 4
Locate the hex screw in the center interior of the connector housing and insert the proper hex wrench size onto the hex screw.
Step 5
Remove the hex screw by turning counterclockwise until it is fully extracted from the mic housing. The bottom section may now be pulled off, exposing the transformer wiring assembly and transformer. The transformer can be pulled from the microphone body if necessary.
Taking Apart the RE20 Top Section
Step 1
Locate the two set screws along the seam of the top grille assembly.
Step 2
Insert a screwdriver and remove the two screws by turning counter clockwise until they are fully extracted from the grille housing.
Step 3
Grasp the grille and turn it counterclockwise until fully removed.
Step 4
Remove the cylindrical windscreen and side wind shield by lifting them off to expose the mic head for inspection or replacement.
Tips
- If replacement of parts is necessary, create a written wire diagram to ensure in correct wire placement during soldering.
Warnings
- There are no user serviceable parts within the transformer or connected wiring assembly. Attempting to dismantle the transformer or assembly may cause transformer damage.
- Handle all parts gently to avoid damaging the delicate wires soldered to components.
