4-Wire Modular to PJ327 Adapter

  • Converts a standard modular headset amp 4 wire modular interface into a 2 prong interface
  • Allows you to plug a 4-wire handset into a 2 prong port
  • Use this an an alternative to using a 2 prong amplifier (such as the Plantronics P10) — this allows you to plug a modular headset amplifier into a phone with that has 2 prong headset port
  • You would use this adapter because it is easier to reach the incoming volume contol on a modular amplifier (M22 for example) and the modular amplifier also has a handy mute button…or perhaps you already have the modular amplifier and it is less expensive to add this adapter
  • Also called an M2A Adapter
  • Genuine Plantronics accessory
