If you're looking at this ad, then you probably already know what this thing is and that it retailed back in the day for MSRP $10,000...
"The MC-12B does just about everything that can be done at this point:
☛ Dolby Digital, EX, and Pro Logic II;
☛ DTS and DTS ES (both the matrixed and discrete variations);
☛ THX; and
☛ Lexicon's proprietary, highly regarded Logic 7 format (with Film, TV, and Music modes), which offers up to seven channels of sound for any source and can be applied to other processing modes, as well..."
"There are 12 digital audio inputs, including six coaxial, five optical, and an AES/EBU jack, as well as eight analog audio inputs, which you can configure as eight regular inputs or five inputs plus the 5.1-channel input. As for video inputs, there are five composite, eight S-video, and four high-bandwidth component video, including one with BNC connections."
"Although not marked on the front, this unit is B-version so the main audio outputs are fully balanced, with dual differential 24/192 DACs in each channel."
This unit originally belonged to my father-in-law. We've been forced to liquidate his things, as he is moving to an assisted living facility.
You will receive the MC-12B unit, the power cord, and an aftermarket remote control (sorry that we could not find the original remote). No other cables or items are included.
Also, my apologies that we could not find the manual; however, the manual can be downloaded here: https://data2.manualslib.com/pdf2/39/3826/382525-lexicon/mc12__rev_4.pdf?ab293bea0aec66d443225061549f62ea&take=binary
This unit worked perfectly when it was originally set up, but all the a/v pieces attached to it are long gone, so I have limited ability to demo it (except with our video game console). If I deliver it (which I'm happy to do), you are more than welcome to hook it up to your own stuff and fully test it out before purchase. Either way, I can guarantee that it's fully functioning,
We're located in north Phoenix near Cactus Rd & 32nd Street, just off the 51 Piestewa Fwy.
You can come pick it up here (and I'll give you a 14-day warranty), or I'd be happy to deliver it (and of course, wait while you hook it up to test it).
I regularly run errands around the metro area, so delivery is no problem.
