- Provides full, efficient and flexible coverage – fewer microphones required
- Small-diameter capsules near boundary eliminate phase distortion and deliver clear, high-output performance
- Low-frequency attenuation improves sound pickup without affecting voice quality
- Cable routes through any of four recessed pathways on the microphone base (or down for direct feed through a table surface); no tools or disassembly required
- UniGuard® RFI-shielding technology offers outstanding rejection of radio frequency interference (RFI)
- Heavy die-cast case and non-slip silicone foam bottom pad minimizes coupling of surface vibration to the microphone
- Low-profile design with low-reflectance finish for minimum visibility
