The microphone is on a 1 square meter table, The artificial mouth is 1 meter away from the microphone and 30 cm above the table. Measured under anechoic conditions. Note: Microphone must meet noise and sensitivity requirements of Lync Room Specification Rev G. Frequency Response Limit See Frequency Response Limits below. Sampling Rate 48KHz Sampling Rate Accuracy <0.04% Mic EQ Setting Support Bit Depth 16 bits Capture Latency <10ms Capture glitch count per 5 minutes ≤2 DC offset <±15% Send Noise < -66 dB DFS, A-weighted. DFS = Peak Sine Wave Send single frequency interference ≤-70 dBm0, A-weighted
Page 5 of 8 Send Harmonic distortion <2%, 250-4000 Hz Drift between microphone signals The ADCs for the two microphones need to be phase locked with 0 sample offset between the mics. Microphone sensitivity mismatch Less than 3dB between the two microphones (including preamp and ADC) Microphone phase mismatch Less than 10 degrees between the two microphones (including preamp and ADC) Crosstalk between microphone channels <-90dB Capture stream timestamp The maximum timestamp error must be <0.5ms and the timestamp error standard deviation must be <0.04ms PC Operation System WIN7 The on axis response measured at the front of the microphone, with the microphone setting on a table in anechoic room and using artificial mouth sound source located 1 meter away from the microphone and 30 cm above the surface of the table the frequency response shall be within the following limits: Upper Limit Lower LimitHz dB Hz dB 90 0 224 -99 224 0 224 -6 224 2 280 -6 1120 2 280 -4 1120 3 1000 -4 1800 3 1000 -4 1800 4 5600 -4 9000 4 5600 -10 2.2.1 System Frequency Response Limits
