An unusual task for my Rumble today. We listened to a baroque concert that was live streamed via YouTube. I ran it on my tablet, from there I went directly into my Rumble 15. On the Rumble I chose the bass input over the aux input, because the volume and EQ knobs only control the bass input.
Settings: on the tablet I set the volume on full, since I know from experience this gives the best, fullest sound. On the Rumble the volume was only at 8:00, which was enough for our 13'x24' living room.
EQ: low at 1:30, mid at noon, high at 10:00. This was because the overall sound was rather top heavy, as all five singers were female.
They played and sang beautifully! Evening well spent.
