EEG-SMT: Using 1 Channel only?

[Axel]

Hi,

I want to use 1 Channel only. Circuit diagram says, I should connect the unused channel inputs to V_REF. But, it is not easy to do this, is it?

Is it fine to connect to GND (ground, outer pin of plug), instead?

Best regards,
Axel

I think you must connect the channel +/- to the drl, you can use a 3.5 splitter like these

Hi Kris,

thank you for your advise. The 3.5 splitter is a great idea, I didn't know that such a thing exists!

Is the DLR connection unused when receiving the signals from just one channel?

DRL is always required. It is not optional when you use just one channel.
