mif4 Instruction Manual
Rosendahl mif4 is a professional midi timecode
interface with LED display, sync input and USB
port
www.rosendahl-studiotechnik.com
Unpacking and mounting into a 19" rack
mif4 comes with the following accessories:
1 x USB power adapter
1 x USB cable A-B
2 x 1U rackmount brackets with screws
The unit is shipped with four rubber feet mounted
underside with Phillips screws.
If you want to rackmount your mif4, please
detach the four rubber feet and pull off the
protective film from the two aluminium brackets.
Remove the black countersunk screws on the
left and right side of the unit to assemble the
rack mount brackets using the 8 enclosed
Phillips screws.
Powering up & selecting timecode SOURCE
Connect the USB port to a host computer or use
the external power adapter to supply your mif4.
Each time the unit is powering up the installed
firmware and hardware version are shown in the
display for two seconds.
This manual relates to firmware version 3.0 from
September 2021.
The left key is used to select the timecode
SOURCE.
Short keypresses will navigate through the four
input modes:
LTC: longitudinal timecode (SMPTE 12M) from
the LTC IN
MTC: midi timecode from the MIDI IN.
USB: midi timecode from a host computer
connected via USB.
GEN: manually or MMC controlled timecode
generator mode.
Holding down the left key for two seconds
causes
(1) a JAM SYNC from applied, running timecode
into the GEN mode
(2) or if no timecode signal is present, you will be
able to store the default SOURCE setting to
non volatile memory.
(See generator section for more informations
about JAM SYNC)
LTC input mode
LTC is longitudinal timecode according SMPTE
12M, there are 80 bits containing time, userdata
and a syncword.
The unit detects the incoming LTC frame format
automatically..
The FPS LEDs 24, 25, 30 and DF indicate the
detected format.
24 FPS timecode is used for movie productions.
25 FPS timecode is the standard European video
frame rate but is also common for European
audio productions.
30 FPS timecode is used for audio and high
definition video productions in Japan and the US.
30 FPS pull down resulting in 29.97 FPS is used
for NTSC or high definition video productions
(pull down).
30 and DF indicates the drop frame format used
only for pull down video applications where
correlation to time of day is mandatory.
These LEDs are all unlighted if no input signal is
applied, so they also serve to indicate ISP (Input
Signal Present) status.
Continious timecode, running forward, within
+/- 6% of nominal speed will be translated into
MTC timecode and sent to the MIDI and USB
output ports. Simultaneously stable, regenerated
LTC is fed to the LTC output.
