Take Apart An Electrovoice Pl20

The Electro-Voice PL20 was a dynamic cardioid microphone widely used in both broadcasting and music recording applications. The PL20 looks and sounds identical to the popular RE20 model, which has become a staple in any recording engineer's microphone cabinet. According to Coutant.org, the PL20 was discontinued due to the fact that the only real difference between the PL20 and RE20 was the prefix. If you plan on performing any routine maintenance or repairs to your microphone, you must be able to dismantle it without causing damage.


Instructions


1. Place the microphone flat on a padded work surface. Plug in your soldering iron, and heat it up for about 10 minutes. Unscrew the main cover on the top side of the microphone. Grasp the foam revealed by the cover, and pull it out of the microphone. This will reveal the main capsule and internal wiring.


2. Lift the main capsule out of the main, vented windscreen. Do not pull it out all the way. There are still two wires soldered to the capsule. Touch the heated soldering iron to each wire where it meets the solder joint on the capsule. Do this until the solder melts and disconnects from the capsule. Remove the capsule from the microphone.


3. Lift the main windscreen cover off of the microphone's base, and set it aside. Locate the three-pin, male XLR (microphone cable) connector on the bottom side of the microphone. Twist the connector until it pops out of the mic's casing. Unscrew the large hex screw revealed by the XLR connector.


4. Desolder the three wires from the XLR connector with the heated soldering iron. Remove the connector from the base of the microphone's housing. Slide off the bottom section of the microphone's housing to reveal the internal wiring.
