Product Overview
The Audio-Technica AT4049b-EL is a omnidirectional head capsule (element only) for the AT4900b-48 modular microphone body. It lets an integrator add or change the omnidirectional polar pattern on a 40 Series modular microphone without replacing the body. It is a precise option for studios and installs in broadcast studios, auditoriums, and houses of worship.
Product Description
This is the omnidirectional head capsule only; it threads onto the AT4900b-48 modular microphone body (sold separately) to form a complete microphone. Buying capsules separately lets a facility stock multiple polar patterns against a smaller inventory of bodies.

The omnidirectional pattern determines the microphone's pickup, so an engineer can re-tune an installed modular microphone to the room or source by swapping the capsule. The assembled microphone operates on 48V phantom power.
The complete fixed versions are also available: see the AT4900b-48 body that this capsule requires.
