Hello,
I've read thoroughly the Quickstart guide and the Users Guide and still a little confused on the connections for 2.1 configuration (Left and Right Mains, Single Ended, and Subwoofer BTL).
My questions are:
1. Do I need a separate input for the subwoofer channel (0.1) ? The User manual seems to imply this. I see it says Left to Input C, Right to Input D. But then it says "For single-ended subwoofer (mono) input, connect RCA male jack to female RCA jack input A/AB (RED) and set J4 jumper positions to SE. • For differential subwoofer (mono) inputs, connect positive RCA male jack to female RCA jack input A/AB (RED) and connect negative RCA male jack to female RCA jack input B (YELLOW) and set J4 jumper positions to DIFF." I only have a Left and Right output from my source.
2. The user manual says "Single-ended input settings on the TPA3255EVM should only be used for channels with output configuration BTL or PBTL, not SE". So, in 2.1 configuration, does this mean I cannot have Single Ended inputs because my Left and Right Outputs are Single Ended?
3. If I go with differential inputs, does that mean a Balanced cable (TRS or XLR) in for each Left and Right? How would I hook that up, there's only RCA inputs?
4. For my L & R Speaker Outs, the User manual is clear on where to hook up the positive speaker wires. Do I hook up the negatives for each speaker at the black ground terminals in the middle of the output section? Does it matter which one or are they connected?
Thank you for all help!!
Marc
