Primo EM272 Technical Data

Should I use an EM272 or EM273?

The EM272 and EM273 are physically identical, they share the same housing and diaphragm.

• The EM272 has a 2 wire connection and is the easiest to use, it can be wired directly directly to most domestic recorders which have 3.5 mm microphone sockets and supply plug in power.
• The EM273 has a 3 wire connection, its the 3 wire version of the EM272. It has no internal resistor from the source to ground, if you add a 100 ohm resistor between source and ground on the EM273 its identical to the EM272, of course you can select a higher value for less sensitivity.
  
  Soldering information:
  

• These electret capsules have solder pads for electrical connection.
• The FET is mounted within the case and can be damaged by overheating or over voltage.
• We recommend use of a low power or temperature controlled soldering iron (for instance 18 watts) and to keep contact of the iron to the pad as brief as possible.
• Please see our brief video demonstrating the ideal way to solder these capsules  Soldering Primo EM172 Capsules
• We also supply the capsules with presoldered wires item FC012 etc
