This system has a highly sophisticated graphic equalizer. It also has recording/editing capabilities, tape dubbing between the two cassette players, microphone mixing and time-activated operations. The four components (radio/tuner, amplifier, dual cassette deck and CD player) can be stacked two-high or four-high, whichever you prefer. The remote control works great and doesn't have a corroded battery compartment. Has all original packaging minus a couple foam inserts. Everything sounds great! I was honestly surprised at how much of a beast this thing is. IMPORTANT: The cassette player will not spin but does turn on and when I try to use it, I can hear it trying to spin. I'm not sure what it's problem is but it responds to everything I try with noise as if it wants to work. It could be a belt issue (I've seen that be the case with others).
