I purchased two Era 100s to create a stereo pair and connect to my iMac for computer audio. I purchased the line in adapter. Audio via line in is incredibly quiet. I went to the line in settings and set level to “mac computer”, and that barely helped. I finally set level to 10 (the highest available) but even with my iMac volume set to max, it was a very quiet sound coming from the speakers.
I switched to Wi-Fi connection, and the audio was super loud, so I know it’s not an issue with the speakers themselves.
How can I increase the audio volume for line in from my iMac?
