bfd question

[agtpunx40]

how do people have theirs hooked up. I can't find a mono to 1/4" adapter on the radio shack. Am I going to be stuck with using 2 adapters one for mono to stereo and one for stereo to 1/4" mono?

well, I found a rca to 1/4" adapter on parts express, but I then noticed that the input on the bfd is "1/4" trs." What does the TRS mean and could I just use a regular 1/4" adapter or is it something different? Thanks
