- Adjust Input Level: Within your computer's sound settings, adjust the input volume or gain level for the microphone to an appropriate level. Monitor the input meter to ensure audio is being captured without clipping or distortion.
Operating Instructions
The MXL AC-44 is designed for straightforward operation:
- Power On/Off: The microphone is powered via the USB connection. It will activate automatically when connected to a powered USB port. There is no manual power button.
- Audio Pickup: The microphone's wide cardioid polar pattern captures sound effectively from a 180-degree area in front of the unit. Ensure speakers are within this range for optimal performance.
- Optimal Distance: For best speech intelligibility, position the microphone within a 25-foot radius of the speakers.
- Application Use: Once configured in your system settings, the MXL AC-44 will function as the audio input for any compatible software (e.g., video conferencing platforms, recording applications). Select it as the microphone within the application's audio settings if it doesn't default automatically.
- Monitoring (if applicable): If your computer or software provides a monitoring option, you can listen to the microphone's input through headphones connected to your computer's audio output. The AC-44 itself does not have a direct headphone jack for monitoring.
