Please do not be confused with other stuff offered as LOMO, or even alike LOMO public address channel strips, well-made, but much less complicated, these particular modules were used in professional movie studio recording consoles, with different approach in quality and versatility, they are becoming extremely hard to find, and considering that there were only about 12 major movie-studios in the former USSR, each equipped with 1-2 of such consoles they will soon be (if ever) only available in aftermarket.
Refer to pics for cosmetics, what you see is what you get, unit is tested, fully serviced and are in plug-and-play condition, 33V PSU, cables with sockets provided, but due to delicate nature of vintage electronics sold as-is with NO returns, so to avoid unpleasant situations and unweighted decisions, please ask all questions you may have BEFORE bidding.
We usually ship within 3-5 days after receiving cleared payment.
