DAQmx with different microphone sensitivity

[CCHUA1994]

First day using Labview, 

DAQmx only allow to key in one microphone sensitivity but I have two microphone with different sensitivity for simultaneous measurement. So how can I create another channel for two microphone?

Put two of those DAQmx create channels one right after the other.  First one with first physical channel and its sensitivity, second with the second physical channel and its sensitivity.  The task wire that comes out of the first one will enter the second one.  DAQmx allows you to build up tasks this way.

Use block diagram cleanup.  I think some of the constants you have wired aren't entering the subVI's at the correct places.

Hi, if I configured in this way, will the signal measurement from these two microphone get mixed up?

Thank you for your advise on cleanup.

No. Why should DAQmx mix them up?

Btw. when you configure two or more channels in your DAQmx task then you should set DAQmxRead to read "NChan…" instead of just "1Chan…"!
