I'm trying to integrate a sub into my 2-channel system to see how it sounds, and i'm not sure the best way to go about it.
I have an Adcom pre that has 2 sets of unbalanced outputs and 1 set of balanced outputs. Currently I'm using one set of the unbalanced outputs going to my amp and the second set and balanced are free.
My subwoofer has a single RCA input, so my first thought was to use the second set of outputs and using a y-adapter connect it to my sub. I have some sort of Rat Shack cable lying around that has 2 RCA's on one end and 1 RCA on the other, which seemed like it'd fit the bill. When I hook it up the sub functions as it should, but my speakers operate in mono mode, which I'm assuming is because the sub cable is jumpering the left and right channels together. If I unplug one of the cables from the preamp then everything functions as it should, however then I'm potentially missing bass information from one channel.
So I guess I have two questions:
1. What's the best way to integrate a sub into my setup
2. Is my current cable the cause of the problem and will I be able to use a Y adapter to make this work, or will it always jumper the 2 channels together and cause the main output to be mono? Do I need some sort of active electronic solution for this?
