Hi everyone. Please excuse me I am not very technically minded just need a little help. I am replacing my era 100 (2 of them) with era 300. Do I just need to add them to my existing system & then follow the app instructions? Many thanks for your help & any info you thinkย  might help would be great. The era 100 are going in another room by the way.๐Ÿ˜ƒ

Since you are replacingย them, you might want to change the name of the room the 100โ€™s are in, so it will be free for the 300โ€™s.

If the Era 100โ€™s are being used as surrounds youโ€™ll need to remove them from the Soundbar using the app under โ€œremove surroundsโ€ before adding the Era 300โ€™s. To add the Era 300โ€™s as surrounds first set them up as separate rooms then go to the room with the soundbar and select โ€œadd surroundsโ€.

If the Era 100โ€™s are being used as a stereo pair just move them to the new room and change the room name in the app. Setup the Era 300โ€™s as separate rooms first then create the stereo pair and name them to the room where the Era 100โ€™s were.

I found naming the new surrounds Rooms L-surround and R-surround when first adding them to the system kept me from getting confused.
