Hello I am new to this site but often come here to look for answers to some audio and/or tech queries. I see some posts for this particular model but cant find what I am looking for this time.
I have two AKIA/SW-155 with no manual.
There are two interfaces on the back and both look like they are for audio, one being a two pole phone jack the other being twin pole pinch but also might be for power.
I’m trying to understand if they are passive or if I need to power them.
Can anyone advise?
