Next-generation Noise Cancellation with adaptive modeling to room ambient noise condition
Increased resolution on Microphone Preamp stage(0-56 dB in 7 dB increments)
Pre-AEC routing for Sound Reinforcement Applications (Maximum of 4 millisecond processing delay)
Integrated Ethernet and USB connections
SNMP and HTML remote management agents
Event scheduler
Diagnostic console
Simplified Configuration Software
Drag & drop A/V and channel objects
Selectable views—unit, matrix, channel
Expanded Serial Command List
First-mic priority delivers clear audio to the far end
20 Hz-22 kHz bandwidth for full-range audio response
ALC & AGC keep participants’ audio balanced and consistent
