Setup Instructions

Follow these steps to assemble and connect your microphone system.

  1. Attach the Articulated Arm: Securely clamp the articulated arm to a stable surface, such as a desk or table, using the integrated clamp. Ensure it is tightened sufficiently to prevent movement.
  2. Mount the Anti-Shock Basket: Screw the anti-shock basket onto the threaded end of the articulated arm.
  3. Insert the Microphone: Carefully place the Genesis Radium 300 microphone into the anti-shock basket. The basket is designed to isolate the microphone from vibrations.
  4. Attach the Pop Filter: Mount the pop filter to the articulated arm or desk using its clamp. Position the pop filter approximately 2-3 inches (5-7 cm) in front of the microphone capsule.
  5. Apply the Sponge Sleeve: If desired, place the sponge sleeve over the microphone capsule for additional wind noise reduction.
  6. Connect the XLR Cable: Connect the XLR end of the provided cable to the microphone. Connect the 3.5mm mini jack end to your computer's microphone input or compatible audio interface. For professional studio equipment, an XLR-to-XLR cable (not included) may be required.

Operating Instructions

Microphone Placement and Usage

The Radium 300 XLR is a cardioid condenser microphone, meaning it primarily picks up sound from the front, while rejecting sounds from the sides and rear. This characteristic is ideal for vocal recordings, streaming, and podcasting to minimize ambient noise.

  • Optimal Distance: Position the microphone 6-12 inches (15-30 cm) from the sound source (e.g., your mouth) for clear audio.
  • Pop Filter Function: The pop filter helps to reduce plosive sounds (like 'p' and 'b') and protects the microphone from moisture. Ensure it is correctly positioned between you and the microphone.
  • Anti-Shock Mount: The anti-shock basket minimizes vibrations transmitted through the desk or arm, ensuring cleaner recordings.
  • Signal Splitter: The microphone features a signal splitter, allowing simultaneous connection of headphones via a minijack for monitoring audio.

Software Configuration (PC/Laptop)

After connecting the microphone, you may need to select it as the default recording device in your operating system's sound settings and any recording software you use.

  1. Windows: Right-click the speaker icon in the taskbar, select "Sound settings," then navigate to the "Recording" tab. Select "Microphone (Realtek High Definition Audio)" or similar, set it as default, and adjust levels.
  2. macOS: Go to "System Preferences" > "Sound" > "Input." Select the connected microphone and adjust the input volume.
  3. Recording Software: Within your recording application (e.g., OBS Studio, Audacity, Discord), ensure the Genesis Radium 300 is selected as the audio input device.

Maintenance

  • Cleaning: Use a soft, dry cloth to clean the microphone body and accessories. Do not use liquid cleaners or solvents.
  • Pop Filter: The pop filter can be gently cleaned with a damp cloth if necessary. Ensure it is completely dry before reattaching.
  • Storage: When not in use for extended periods, store the microphone in a clean, dry environment to protect it from dust and moisture.
  • Cable Care: Avoid sharp bends or kinks in the XLR cable to prevent damage.

Troubleshooting

No Sound Output:
  • Ensure the XLR cable is securely connected to both the microphone and the input device.
  • Verify that the microphone is selected as the default recording device in your operating system's sound settings.
  • Check the input volume levels in your operating system and recording software.
  • Test with a different cable or input port if available.
Poor Sound Quality / Background Noise:
  • Ensure the pop filter is correctly positioned to reduce plosives.
  • Verify the microphone is securely seated in the anti-shock basket to minimize vibrations.
  • Check microphone placement relative to the sound source and ambient noise. The cardioid pattern reduces side and rear noise.
  • Adjust gain levels to avoid clipping or excessive background hiss.
Microphone Not Recognized:
  • Try connecting the microphone to a different USB port or computer.
  • Ensure your operating system drivers are up to date.
