Setup
Follow these steps to set up your microphone:

- Position the Microphone: Attach the microphone to a stand using the adjustable swivel adapter. Adjust the angle and height for optimal sound capture. The omnidirectional polar pattern means it picks up sound equally from all directions.

Operating Instructions
The RadioShack PA Omnidirectional Dynamic Microphone is designed for general-purpose audio capture. Its omnidirectional pattern makes it suitable for picking up sound from multiple sources around the microphone.
- Speaking/Singing: Hold the microphone comfortably or position it on a stand. Speak or sing directly into the grille.
- Volume Control: Adjust the volume on your connected audio equipment. Avoid setting the volume too high to prevent feedback or distortion.
- Proximity Effect: Due to its omnidirectional nature, this microphone exhibits less proximity effect (bass boost when close to the source) compared to directional microphones.
Maintenance
Proper care will extend the life and performance of your microphone:
- Cleaning: Wipe the microphone body with a soft, dry cloth. Do not use liquid cleaners or solvents.
- Storage: Store the microphone in a dry, cool place away from direct sunlight and extreme temperatures.
