Far from run-of-the-mill indeed. It retailed for $3500 back in '93. It is more advanced then 95% of the head Units on the market today.
It operates in full digital all the way to the RCA-analog outputs, even the AM/FM reception is converted to digital. It sends the digital signal through a fiber optics cable to the processing unit. In the processing unit there are four slots for digital to analog converters each with 2 stereo ch ouputs for a total of 14 chs, the most from ANY car audio in dash unit. The last slot are sub outs in mono thus giving 14 chs, 6 stereo (12 chs) and 2 mono ( chs 13 and 14). You can set this up to run midbass/midrange/tweeter at all four corners actively and 2 sub chs, each output also has its own time delay, level attenuation, xover slopes of 12/18/24/30/36 dB/Oct, 6 band parametric EQ, adjustable Q (5 points).
It's so far advanced, even for todays standards, that it'll take about 2-3 hrs to set this up WITH an RTA. The big ass remote is what that's for. The smaller remote is for the everyday adjustments.
Here's the real kicker......................
I wont be installing it. :scared-eek:

It's for collectors purposes only. Part of my stash. :mrgreen: I will get it set up though in my bedroom with it's own special display.
