SupercardioidAudix UEM81S

Supercardioid Condenser Microphone

The UEM81S is a medium length shotgun mic with a pre-polarized (electret) condenser capsule, based on the Audix PS-81 modular head amplifier.

The PS-81 operates on (and requires) a single AA battery, rather than phantom power. Two switches on the mic body set on/off and high-pass filter enable.

The capsule is removable and can be replaced with the CPS-81C Cardioid module; that combination is the Audix UEM81c.

The UEM81S ships with:

  • Modular preamp supply with on-off switch and bass roll-off filter (PS-81)
  • Modular cardioid capsule (CPS81S)
  • Tension-fit clip (MC81)
  • External Foam Windscreen (WS81S)
  • 20' XLR-XLR mic cable
  • 1 AA Battery
  • Vinyl carrying box

The Audix UEM81S is also known as: UEM81-S.
