Hello,

Is there any way to use multi part component in multichannel design? Please see the image below from Altium's reference. In channel 2 Altium places a new part as U4_2 but I want it U4_1B. Do you know how can I do that?

I do not know one. We usually use dual channel amp like bottle neck for multychannel. So all what is before it is in multychannel ( different schematic) and all what is after (different schematic) There will be sad schematic with only amp in it. but we do that. I have done 8 channel boards, so filters, ATTs and amps was for each channel (we called them Filt_W1....Filt_W8) and 4 channel of 2dual channel amps (AMP_A1...AMP_A4) and that again 8 channel for mixers and amps (Mixed_W1...Mixed_W8) and alld down to two channels of 4 channel ADCs (ADC_1, ADC_2).

Hi You can play with designator format settings to get your desired format.Refer attached.

I do not use multichannel designs, but, I am not sure if what you are trying is possible. I would expect, that the components used would need to be exactly the same in every channel, however multipart components do not have to be the same, so I would not be surprised if that would be one of the reasons why it is not possible. Still if it is possible, please let me know.
PS: I would probably create a schematic which would include both parts and use this to create additional channels.

Hi @robertferanec ,
Please refer the attached picture by using that strings we can get the desired designator for every channel right?
