Overview
Speech intelligibility - low noise
This solution uses the MMC4018 Cardioid Microphone Capsule, which has a highly-directional supercardioid pickup pattern with a smooth and uniform off-axis frequency response. The supercardioid shape is frequency independent, securing an identical sound color around the microphone. The usual rear lobe heard on most supercardioids is minimized on this capsule. This makes it much more isolated without sudden frequency dependent peaks and dips.
- With XLR Connection
- Outstanding audio quality
- Wireless podium mic capability
- Highly directional – very isolated
- High rejection of radio frequency interference
- Sleek Scandinavian design
DPA gooseneck microphones have quickly become a very popular choice for podium mics as well as for conference room usage as either tabletop or ceiling mount. They are used at parliaments where multiple languages are to be simultaneous interpreted and the interpreters must catch every word and nuances of the spoken word and in a split second deliver the perfect translation.
