3. Setup

Follow these steps to set up your CAD Audio D90 microphone for use:

Attach Microphone Clip: Secure the included microphone clip to a standard microphone stand. Ensure it is tightened sufficiently to hold the microphone firmly.
Insert Microphone: Gently insert the CAD Audio D90 microphone into the microphone clip. Adjust the angle as needed for optimal positioning.
Connect XLR Cable: Connect a standard 3-pin XLR cable to the microphone's output connector at the base. The D90 is a passive dynamic microphone and does not require phantom power.
Connect to Audio System: Connect the other end of the XLR cable to an input on your mixer, audio interface, or amplifier. Ensure the input gain is set to a low level before powering on your audio system.

4. Operating Instructions

To achieve the best performance from your CAD Audio D90 microphone, consider the following operational guidelines:

Microphone Technique:

Proximity Effect: The D90 exhibits a proximity effect, meaning bass response increases as the microphone is moved closer to the sound source. Experiment with distance to achieve desired tonal characteristics.
On-Axis Placement: For optimal clarity and frequency response, position the microphone directly in front of the sound source (on-axis).
Off-Axis Rejection: As a supercardioid microphone, the D90 is highly directional. Point the microphone away from unwanted sound sources (e.g., stage monitors, instruments) to minimize bleed and feedback.

Gain Staging:

Start with the input gain on your mixer or interface at its lowest setting.
Gradually increase the gain while speaking or singing into the microphone at your typical performance volume.
Adjust the gain until the signal is strong without clipping or distortion. Aim for a healthy signal level that allows for headroom.

5. Maintenance

Proper maintenance will extend the life and performance of your CAD Audio D90 microphone:

Cleaning: Regularly wipe the microphone body with a soft, dry cloth. For the grille, use a soft brush to remove any debris. Avoid using liquid cleaners directly on the microphone.
Storage: When not in use, store the microphone in its included hard-sided road case or a protective pouch to prevent dust accumulation and physical damage.
Avoid Moisture: Keep the microphone away from moisture and extreme temperatures.
Handle with Care: While durable, avoid dropping or subjecting the microphone to harsh impacts.

6. Troubleshooting

If you encounter issues with your CAD Audio D90 microphone, refer to the following common problems and solutions:

Problem	Possible Cause	Solution
No Sound Output	Faulty XLR cable Incorrect input selection on mixer/interface Gain set too low Microphone not connected properly	Test with a different XLR cable. Verify the correct input channel is selected and unmuted. Increase input gain gradually. Ensure XLR cable is fully seated in both microphone and audio device.
Distorted Sound	Input gain set too high Damaged microphone element	Reduce input gain on your mixer/interface. If distortion persists at low gain, contact CAD Audio support.
Excessive Feedback	Microphone pointed towards speakers/monitors Too much gain Room acoustics	Reposition microphone away from speakers. Reduce input gain or master volume. Utilize EQ to cut problematic frequencies.
Weak Signal	Low input gain Incorrect microphone technique (too far from source)	Increase input gain. Move microphone closer to the sound source.
