I have just recently upgraded my computer tower and gotten myself a Bose Companion 20 Multimedia Speaker set to accompany it. So, soon afterwards, I went to plug in my Alesis Multimix 8 USB FX into the tower, and then my computer suddenly went mute. I then found out that the speakers needed to be plugged into the mixer that I had in order for it to work. Sadly, they didn't tell me which adapter to use in order to connect it so. So, would it be a jack adapter that was 1/4 inch to a mini 3.5mm, or something completely different? Or, if there's no possible way to connect the two, would my best option be to get an XLR-to-USB cable and sell the mixer?
I've been falling behind on my lines because of this issue, and I hope to get some support for this soon. Thank you kindly for your time.
