Operating Instructions

The U7 microphone is designed for optimal performance in various audio capture scenarios.

Omnidirectional Pickup: The microphone features an omnidirectional pickup pattern, meaning it captures sound equally from all directions (360 degrees). This makes it suitable for recording multiple speakers around a table or capturing ambient sound.
Speech Tailored Frequency Response: The U7's frequency response is specifically tailored for speech, ensuring clear and intelligible voice capture for dictation, online meetings, and voiceovers.
Application Use: Once connected and selected as your input device, the microphone will work with any audio recording or communication software (e.g., Skype, Zoom, Microsoft Teams, voice recorders, dictation software).
Monitoring Audio: Most software applications allow you to monitor the microphone's input level. Adjust the input gain within your software settings to prevent clipping (distortion) or ensure adequate volume.

Maintenance

Cleaning: Use a soft, dry cloth to clean the exterior of the microphone. Do not use abrasive cleaners, solvents, or chemical sprays.
Storage: When not in use, store the microphone in a clean, dry environment, away from dust and extreme temperatures.
Cable Care: Avoid sharp bends or kinks in the USB cable to prevent internal damage.

Troubleshooting

Problem	Possible Cause	Solution
Microphone not detected / No sound input	USB cable not fully connected. Incorrect input device selected in system settings. USB port issue. Operating system driver conflict.	Ensure the USB cable is securely plugged into both the microphone and the computer. Verify that "CAD Audio USB U7" is selected as the default input device in your computer's sound settings. Try connecting the microphone to a different USB port on your computer. Restart your computer. If issues persist, check for operating system updates or consult CAD Audio support.
Low volume or poor sound quality	Microphone too far from sound source. Input gain too low in software settings. Environmental noise.	Position the microphone closer to the speakers. Increase the input gain/volume level in your computer's sound settings or the application you are using. Minimize background noise in the recording environment.
Distorted audio	Input gain too high. Microphone too close to sound source.	Decrease the input gain/volume level in your computer's sound settings or the application. Move the microphone slightly further away from the sound source.
