Shure PA411 Microphone Specification

The Shure PA411 Microphone is designed to deliver exceptional audio performance for professional sound reinforcement and recording applications. It features a highly sensitive cardioid dynamic capsule that ensures excellent off-axis noise rejection, making it ideal for capturing clear and focused sound in live environments. The robust construction of the PA411 includes a die-cast metal body and hardened steel mesh grille, providing durability and reliability in demanding settings.

The microphone operates across a wide frequency range of 50 Hz to 15 kHz, capturing detailed low-end, natural midrange, and crisp high frequencies. With an output impedance of 150 ohms, it is compatible with most audio equipment, providing consistent and reliable performance. The microphone’s sensitivity of -54 dBV/Pa ensures it can handle high sound pressure levels without distortion, making it suitable for a variety of vocal and instrumental applications.

Connectivity is facilitated by an XLR output, which ensures a secure and interference-free connection to mixing consoles and audio interfaces. The PA411 also incorporates an internal pneumatic shock mount system that minimizes handling noise, ensuring purity of sound in dynamic performance scenarios. Its ergonomic design allows for comfortable handling, while a matte black finish reduces reflections and maintains a professional aesthetic.

The Shure PA411 Microphone is optimized for both stage and studio use, offering versatility and high fidelity audio capture. It is an ideal choice for vocalists, musicians, and sound engineers looking for a reliable microphone that meets the rigorous demands of professional audio environments.

Shure PA411 Microphone F.A.Q.

How do I connect the Shure PA411 to my wireless microphone system?

To connect the Shure PA411 to your wireless microphone system, use the supplied RF coaxial cables to connect the antenna outputs on the PA411 to the antenna inputs on your wireless receivers. Ensure that all connections are secure to prevent signal loss.

What is the best way to position the antennas for optimal performance?

For optimal performance, position the antennas in a V-shape (45-60 degrees apart) in a location that is elevated and free from obstructions. This helps in maximizing coverage and reducing the chances of signal dropouts.

How can I troubleshoot signal interference with my PA411?

To troubleshoot signal interference, ensure that your wireless systems are set to different frequency channels. You may also need to scan for available frequencies using your receiver's frequency scanning function and adjust the placement of the PA411 to minimize interference sources.

What maintenance is required for the Shure PA411?

Regularly inspect the unit for dust and debris, and clean with a soft, dry cloth as needed. Check all connections periodically to ensure they are secure. Additionally, update to the latest firmware if applicable to ensure optimal performance.

Can the PA411 be rack-mounted?

Yes, the Shure PA411 can be rack-mounted using the included hardware. Follow the instructions in the manual to securely mount the unit in a standard 19-inch rack space.

How do I know if my PA411 is functioning correctly?

The front panel LEDs on the PA411 should be illuminated to indicate power and active antenna distribution. Check that the RF signal strength is stable on your wireless receivers to confirm proper distribution.

What should I do if one of the channels on the PA411 is not working?

Check the connections on the affected channel and ensure the cable is not damaged. Test the receivers connected to that channel on a different working channel to determine if the issue lies with the receiver or the PA411 itself.

Is it possible to use multiple PA411 units in one setup?

Yes, multiple PA411 units can be used in a single setup to expand your antenna distribution system. Ensure each unit is properly configured and connected to avoid frequency conflicts.

What are the power requirements for the Shure PA411?

The Shure PA411 requires an AC power source of 100 to 240 V AC, 50/60 Hz. Use the included power adapter to connect the unit to a suitable power outlet.

How can I minimize dropouts during a performance with the PA411?

To minimize dropouts, ensure that the antennas are properly positioned and that the area is free from obstructions. Avoid placing the PA411 near large metal objects or sources of electromagnetic interference. Regularly scan for available frequencies to avoid crowded channels.
