The Audio-Technica ES905CL Cardioid Rigid-Pipe Installed Mic is a high-performance condenser microphone engineered for professional recording, broadcasting, and sound reinforcement. This contractor-exclusive microphone provides a reliable solution for television applications and demanding acoustic environments.
The ES905CL features a rigid-pipe design combined with a ball-in-socket base to permit flexible positioning for optimal sound pickup. Its sturdy metal base mounts securely to desks, tables, or podiums using the included hardware. This design ensures the microphone remains stable while allowing users to adjust the angle as needed.
A low-profile element provides a uniform cardioid polar pattern with a 120º acceptance angle. This directional focus delivers superior off-axis rejection, which maximizes gain before feedback. To ensure audio clarity, the microphone includes an integral 80 Hz UniSteep filter. This filter provides steep low-frequency attenuation to minimize ambient noise pickup without negatively affecting voice quality. An attached wire mesh windscreen with internal pop protection further reduces interference from wind, ventilation currents, and plosives.
The ES905CL utilizes UniGuard RFI-shielding technology to provide outstanding immunity from radio frequency interference. This microphone is TAA-compliant and RoHS compliant, ensuring it meets specific regulatory standards for hazardous substances and government procurement.
This microphone requires 11V to 52V DC phantom power for operation. The package includes an in-line power module to facilitate professional XLR connections in installed sound environments.
