Videonics MX 1; 4-Input Synchronized Video Switcher in working, good and fresh condition wants to sell is there anyone intrested in buying contact me..

The Videonics Digital Video Mixer is a four-input video production switcher, mixer, frame synchronizer/TBC (Time Base Correc-tor) and special effects generator. Cut, wipe, dissolve between any of four video inputs -- or use any of over 210 digital video effects. Frame synchronizer and time base corrector (TBC) insures clean transitions. Dual-field, infinite-window TBC makes output rock-solid, even if inputs have faulty time base. Unique preview screen shows miniature copies of all four inputs so you can work with just one or two monitors. Effects include freeze, black and white, negative, mosaic, paint, flip, more. Chroma key and compose features, audio mix, more. Model MX-1, NTSC (PAL available).
