Connect microphones to NI myRIO

[nolo]

I need connect 7 microphones to NI myRIO, it is possible ussing the I/0 analog?

Seems that you only can read two channels at the time.

Hack: Use the two anlog out channels as a synced output to control two analog 4:1 muxer -> 8 inputs

Best case: perfect sync, 100kHz update&samplerate gives you 20kSPS per input  ~> 10kHz bandwidth

so I asume you migth get half of it ...

or use 4 myDAQ 😉

Thanks Henrik

The idea is good but this problem is that i  need to read  the 7 entries simultaneously, do not want to lose phase. 

[Henrik_Volkers]

Than you need a 8 channel simultaneous sampling device.

However you do not loose phase by using multiplexed devices, you just have to do some more math 😉

Thank your very much.....

Is motivating your help.........I will consider recomendations....see what we can get through this......
