Ideal for use with professional audio and video equipment, the microphone is fully RoHS-compliant – free from all substances specified in the EU directive on the reduction of hazardous substances (RoHS).- Large-diaphragm capsules offer pristine sound quality and exceptionally low noise
- Innovative coincident capsule configuration produces accurate stereo image in smaller housing
- Compact, lightweight design is ideal for camera-mount use
- Excellent channel separation
- Phantom power operation—for use with professional equipment
- Switchable low-frequency roll-off and 10 dB pad
- Includes one balanced cable (two 3-pin XLRM-type connectors at output)
- RoHS-compliant – free from all substances specified in the EU directive on the reduction of hazardous substances (RoHS)
