What's in the Box
Upon opening the package, verify that all components are present:
- Sony ECM77B Omni-Directional Electret Condenser Lavalier Microphone
- Multiple microphone clips (typically 3 different types)
- Windscreen
- Carrying case
Setup
- Battery Installation (if not using phantom power):
The ECM77B requires two AA batteries for operation when phantom power is unavailable. Locate the battery compartment, typically on the power supply unit connected to the microphone cable. Insert the batteries, ensuring correct polarity.
- Connecting the Microphone:
Connect the microphone's XLR connector to a compatible audio input on your recording device, mixer, or camera. Ensure the connection is secure.
- Attaching the Microphone:
Select an appropriate microphone clip and attach the microphone head to it. Clip the microphone to clothing, approximately 6-8 inches below the speaker's chin, to capture optimal sound. Use the included windscreen to reduce plosives and wind noise.
Operating Instructions
- Powering On:
If using battery power, ensure the power switch on the power supply unit is in the "ON" position. If using phantom power from your recording device, ensure phantom power is activated on the input channel to which the microphone is connected. The microphone will draw power automatically.
- Microphone Placement:
For clear audio, position the microphone on the speaker's clothing, centered on the chest, about 15-20 cm (6-8 inches) from the mouth. Experiment with placement to find the best sound for your specific application. The omni-directional pattern captures sound equally from all directions, offering flexibility in placement.
- Monitoring Audio:
Always monitor the audio output through headphones connected to your recording device to ensure proper levels and sound quality before and during recording.
Maintenance
- Cleaning:
Wipe the microphone body and cable with a soft, dry cloth. Do not use liquid cleaners or solvents. The windscreen can be gently cleaned with mild soap and water, then allowed to air dry completely before reattaching.
- Battery Replacement:
Replace AA batteries when audio quality degrades or if the microphone fails to power on. Always use fresh, high-quality batteries. Remove batteries if the microphone will not be used for an extended period to prevent leakage.
- Storage:
Store the microphone in its provided carrying case when not in use to protect it from dust, moisture, and physical damage. Avoid extreme temperatures and humidity.
