Setup
- Connect to Transmitter: Locate the locking 4-pin connector on the microphone cable. Align it with the corresponding input on your Audio-Technica body-pack wireless transmitter (Gen 3 or earlier). Insert the connector and twist the locking ring clockwise until it is secure.
- Power Module: The microphone's belt-mounted power module operates on either battery power or phantom power supplied by the wireless transmitter. Ensure the power source is correctly configured for your setup.
- Wearing the Microphone:
- Gently place the headband over your head, ensuring it sits comfortably and securely.
- Position the microphone boom so that the microphone element is located at the side of your mouth, typically about 1-2 inches away. This placement helps optimize sound pickup and minimize breath noises.
- Adjust the headband for a snug fit without causing discomfort. The unobtrusive design is intended to remain stable during movement.
- Attach Windscreens: Slide one of the included windscreens over the microphone element. This helps reduce plosive sounds (P, B sounds) and wind noise, improving audio clarity.
Operation
Once properly set up and connected to a powered wireless transmitter, the ATM73cW is ready for use. Follow these guidelines for optimal performance:
- Microphone Placement: Maintain consistent microphone placement at the side of your mouth for uniform sound pickup.
- Gain Adjustment: Adjust the gain (input level) on your wireless transmitter or mixing console to achieve a strong signal without clipping or distortion. Start with a lower gain setting and gradually increase it while speaking at your normal volume.
- Feedback Prevention: Due to its cardioid polar pattern, the ATM73cW is designed to reject sounds from the rear. Position stage monitors or loudspeakers to the sides or front of the microphone, not directly behind it, to minimize the risk of feedback.
- Battery Check: If using battery power, regularly check the battery level of your body-pack transmitter to avoid unexpected power loss during performance.
Maintenance
Proper care and maintenance will extend the life of your ATM73cW microphone:
- Cleaning:
- Wipe the microphone body and headband with a soft, dry cloth.
- For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the microphone element.
- Regularly clean or replace windscreens as they can accumulate moisture and debris.
- Storage: Store the microphone in a clean, dry place, away from extreme temperatures and humidity. Avoid coiling the cable tightly to prevent damage.
- Handling: Handle the microphone gently. Avoid dropping it or subjecting it to strong impacts, which can damage the sensitive internal components.
