Rosendahl Mif 4 professional MIDI timecode interface digital audio workstations as well as lighting and control software make it possible to use mtc MIDI timecode for synchronisation. The new Mif4 provides a professional interface to the ltc (SMPTE time code) standard. Rosendahl Sync algorithms eliminate timecode flicker and dropout. Source = ltc read ltc (SMPTE time code), display and convert to mtc/USB Midi Time Code and regenerate ltc (SMPTE time code). Source = MIDI mtc input, read and convert to ltc (SMPTE) and regenerate mtc/USB Midi timecode. Source = USB read mtc from a USB stick, display and convert to ltc (SMPTE) and regenerate mtc/USB Midi timecode. Source = Gen the timecode generator can be configured and started manually or remotely controlled by MMC MIDI machine control comands. Standard FPS timecode are automatically detected and displayed by the four IPS LEDs (24, 25, 30 frames per second, DF is SMPTE Drop Frame standard). TC = time code display in hours, minutes, seconds and frames. Display = SMPTE UB, 8 bit user aperitif shown hexadezimal. Display = CAL time code informs on speed. Time code 29.97 non-drop for example is indicated by 30 fps LEDs and calibration 0.9990. Display = PAL or NTSC video sync ref (576i, 480i) as well as three HD sync levels (720p, 1080i, 1080p) are automatically detected and displayed with their refresh rates.
