KIT DESCRIPTION 

The KAS-33100-0004 Muskie microphone evaluation kit allows for 

simple and easy evaluation of Knowles SiSonic™ MEMS microphones.  

 

 

Evaluate two input channels of audio from multiple MEMS 

microphone types.  

 

Microphone types include single and differential Analog 

MEMS microphones, Digital PDM MEMS microphones, and 

Digital I2S MEMS microphones.  

 

Wide dynamic range (varies with microphone types and 
audio path). 

 

Selectable Clock Frequencies, Voltages, and Gains. 

 

Multiple Audio Outputs – XLR, 3.5mm Headset Jack, USB 
Audio. 

SIMPLE QUICK START 

1. 

Place suitable microphone assembly correctly into socket. 

2. 

Select audio path and audio signal level. 

3. 

Select Mic voltage and digital clock (if applicable). 

4. 

Connect desired output (XLR, Headset, or USB). 

5. 

Connect USB Cable and turn Power On.

Note: The evaluation kit requires assembled MEMS 
microphones. Usable assemblies include microphones 
mounted to “flex” circuit cards or coupon boards. The kit 
does NOT include assembled Knowles MEMS microphones. 
Microphone assemblies are available separately from a 
Knowles distributer.
