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.
