Inputs The two audio inputs (3.5mm mini-jack and RCA Left/Right) are inputs for connecting the output of your music source (AV receiver, preamble, powered speakers, sound card, TV, etc) into the $8. Both Inputs are open or active, so you can connect twe different sources at the same time and not have to push any buttons to select between each. LFE input If your preamble or AV receiver has an LFE (Low Frequency Effects} output, use the Leftist input on the 58 rear panel.
