Don't confuse the unbalanced wiring to jacks that look like TRS stereo jacks, with splitting mono to stereo ;), you still need to spilt the unbalanced mono to stereo. The TRS jacks here are meant as balanced jacks with unbalanced wiring. >2. Splitting a mono output for a stereo input doesn't need attention, > just stereo to mono needs attention. >3.
