- Microphone Grille: Protects the condenser capsule and helps reduce plosives.
- Body: Houses the internal electronics and battery compartment.
- Power Switch: Controls the microphone's power on/off state.
- Battery Indicator Light: Provides visual feedback on battery status.
- XLR Output: Standard 3-pin connector for audio signal output.
5. Setup
5.1. Battery Installation
The MM-707C/B is battery-powered. Ensure the battery is correctly installed before use.
- Unscrew the lower part of the microphone body to access the battery compartment.
- Insert the provided battery, observing the correct polarity (+/-) as indicated inside the compartment.
- Securely screw the lower part of the microphone body back into place.
5.2. Connecting the Microphone
Connect the microphone to your audio system using a standard XLR cable.
- Connect one end of an XLR cable to the XLR output port at the bottom of the MM-707C/B microphone.
- Connect the other end of the XLR cable to an input on your mixer, audio interface, or amplifier. Ensure the input is compatible with a microphone signal.
6. Operating Instructions
6.1. Powering On/Off
Locate the power switch on the microphone body.
- To turn on the microphone, slide the switch to the "ON" position. The battery indicator light will illuminate.
- To turn off the microphone, slide the switch to the "OFF" position. The battery indicator light will turn off.
6.2. Microphone Usage
The MM-707C/B is a cardioid microphone, meaning it is most sensitive to sound coming from the front and least sensitive to sound coming from the rear.
- Positioning: Point the top of the microphone (grille) directly towards the sound source for optimal pickup.
- Gain Adjustment: Adjust the input gain on your mixer or audio interface to achieve a clear signal without distortion.
- Feedback Prevention: Due to its cardioid pattern, the microphone offers excellent gain-before-feedback. Position speakers behind the microphone to further minimize feedback.
7. Maintenance
7.1. Cleaning
To maintain the microphone's appearance and performance:
- Wipe the microphone body with a soft, dry cloth.
- For the grille, use a soft brush to gently remove any dust or debris.
- Do not use liquid cleaners or solvents, as they may damage the microphone.
7.2. Storage
When not in use, store the microphone in a dry, cool place, away from direct sunlight and extreme temperatures. If storing for an extended period, remove the battery to prevent leakage.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound output | Microphone not powered on Battery drained or incorrectly installed XLR cable faulty or disconnected Mixer/interface input gain too low | Ensure power switch is "ON" Check battery, replace if necessary, ensure correct polarity Check XLR cable connections, try a different cable Increase input gain on your audio device |
| Low volume or weak signal | Microphone too far from sound source Input gain too low Battery low | Move microphone closer to the sound source Increase input gain Replace battery |
| Distorted sound | Input gain too high Sound source too loud/close | Decrease input gain on your audio device Increase distance from sound source or reduce source volume |
| Intermittent sound | Loose cable connection Battery nearly drained | Check all cable connections Replace battery |
