So basically what I'm trying to do is hook up a Vibro Acoustic Bed up. The bed has a speaker that receives power through an amplifier that goes through an audio interface (Alesis io2 express) and plays music from the computer. The computer will play music through a pair of headphones, and bass through the acoustic bed individually, but not separately. I'm asking if there is a way to play the bass through the bed and the rest of the sound through the headphones from a music file at the same time. I'm new to setting up audio equipment and was wondering if this was possible, and if so, how? Ask questions to help me elaborate further. Thank you.
