If you're connecting your laptop directly to your amp, you will need a 3.5mm cable. Simply connect the 3.5mm cable on the back of the amplifier where the label marks auxiliary. Next, connect the other end to the auxiliary input of your computer or laptop. Most of these cables will come in a short length alternative.
Can you connect a laptop to a receiver?
Connect the laptop to the satellite receiver with a piece of coax cable. Connect one end of the cable to the coax port on the back of the TV tuner, and connect the other end of the cable to the port labeled "Coax Out" or "Sat Out" on the back of your satellite receiver.
