5.1 Measurement (Step 1)
- 
                    
Program the device with the merged file from UI, DSP configuration file and firmware.
 - 
                    
Assemble the samples.
 - 
                    
Measure the frequency response of the speaker and microphone of the sample (the recommendation is to use the maximum SPK and MIC gain at this moment).
 - 
                    
If the frequency response is not good, go back to check the mechanical design and assembly. For more details, refer to MIC and SPK Mechanical Design and Placement.
