odd question about my receiver

[dropsonde]

marantz sr4023 is what I have

i would like to know if it's possible to have an LED visualizer kinda like my old JVC amp used to have? just the cool bars and such..

If the Marantz has pre outs, you could probably buy a cheap laptop, and connect cables to it, and find some visualizer program which can respond to the audio input.
