It is a stereo device with two Cardioid Mics. Mic is powered and connected through a signal USB cable. It is required meeting Microsoft Lync Specification Rev. G and designed to be used with Double Black (LRS codec) only. 1.2 Model # LS-0002 1.3 Certifications The product should comply with CISPR22/CE/IEC 60950-1.. 1.4 RoHS All material of device should comply with Logitech 10 restricted Phthalates, (Restrictions are applicable at homogeneous level, at a threshold of less than 1000ppm for each phthalate) 2.4.1 RoHS II 2.4.2 Reach 2.4.3 WEEE 2.4.4 Conflicted material 1.5 Product Main special characteristic Page 2 of 8 2 Electrical Specification 2.1 Block diagram 2.2 Main parameter Microphone Features Item Description Microphone Type Primo EM175 Back Electret Unidirectional Microphone Directional Characteristic Uni-directional Sensitivity -36dB±3dB at 1kHz(0dB=1V/Pa) RL=2KΩ VCC=3V S/N Ratio >72dB Typ. at 1kHz (1Pa,A-weighted ) Max Input Sound Level 120dB S.P.L Microphone Frequency Response Limit Per Primo EM175 Specification Button Feature Item Mute Function Description Mute LED Indicator Item Description Idle Blue LED off / Red LED off In-call Blue LED on / Red LED off Mute Blue LED off / Red LED on Suspend Blue LED off / Red LED off USB Features Page 3 of 8 Item Description USB Type Micro USB USB Compliant USB 2.0 USB Cable Length 4m VID 046D PID 0A4B Item Description Power Features Connection Type Micro USB Female 5V±0.25V USB Voltage Working Current ≤100mA Suspend Current ≤2mA System Features 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 DC offset ≤2 <±15% < -66 dB DFS, A-weighted. DFS = Peak Sine Wave Send Noise Send single frequency interference ≤-70 dBm0, A-weighted Page 4 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 Capture stream timestamp <-90dB The maximum timestamp error must be <0.5ms and the timestamp error standard deviation must be <0.04ms PC Operation System WIN7 2.2.1 System Frequency Response Limits 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 Limit Hz dB Hz dB 90 224 -99 224 224 -6 224 280 -6 1120 280 -4 1120 1000 -4 1800 1000 -4 1800 5600 -4 9000 5600 -10 Page 5 of 8 10 dB Relative -5 -10 100 125 160 200 250 315 400 500 630 800 1000 1250 1600 2000 2500 3150 4000 5000 6300 8000 10000 Hz Page 6 of 8 3 Software function feature 3.1 Button function Desc.

FCC WARNING FCC Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radiofrequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. FCC Caution Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. FCC Warning This equipment has been tested and found to comply with the regulations for a Class B digital device, pursuant to Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference. (2) This device must accept any interference received including interference that may cause undesired operation. Page 8 of 8
