Item Description
Stereophonic Function Support via two Mics
AGC Function Disable
Noise Reduction Disable
Sensitivity -21 dB DFS ± 3 dB
DFS = Peak Sine Wave
Measured with an artificial mouth outputting 94 SPL at
1 kHz at the Mouth Ref Point (MRP). 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:
