Teac MX-2424 v1.04 - Manual (Page 36)

THE MX-2424 MENUS AND WHAT THEY DO:
Menu Bank 000: Rates & References
000 Control Mode
This menu selects the time reference used by the MX-2424 and enables Varispeed operation. (NOTE: It is not
possible to have Varispeed enabled while chasing SMPTE, MTC or another MX-2424 on the TL-Bus. Only a
master machine can have Varispeed enabled.)
Local/TL-Bus Select this if the MX-2424 is operating on the TL-Bus as a Master/Slave, if it is sending
SMPTE or MTC to another device or if it is operating alone. (This is the default setting.)
Timecode Chase Select this to have the MX-2424 chase to SMPTE being generated from another device.
If Menu 002 Sample Reference is set to automatic then digital clock will be derived from
the incoming time code.
MTC Chase Select this to have the MX-2424 chase to MIDI Time Code being generated from another
device.
The MX-2424 does not produce digital clock from MIDI time code (MTC) like it does
from longitudinal time code (LTC) such as SMPTE time code. If you have an audio
device that is sending MTC to the MX-2424 and you want to ensure that the two units
stay in sync, it is recommended that you lock the MX-2424 sample reference clock to the
device generating the MTC. This is done by making a word clock connection from the
device generating MTC to the MX-2424 and selecting External Wordclock in Menu 002.
Varispeed Select this to enable Varispeed operation. Varispeed amount is possible in 0.1%
increments within a +/- 12.5% range. This range is set in Menu 006 and varies according
to the sample rate selected. Varispeed varies the playback frequency as well as any
digital sample clock output from the MX-2424. Varispeed operation is indicated by the
NON-STD LED on the front panel. (NOTE: If the MX-2424 is connected digitally to a
digital console it may be possible to select a Varispeed amount that is out of the
acceptable range of the console and the console will mute. If this occurs it will be
necessary to reduce the Varispeed amount or connect the MX-2424 to the console using
analog connections.)
001 Frame Reference
This menu enables the MX-2424 to use house video sync such as blackburst, composite sync or color bars for
resolve to the edge of the video frame. Both NTSC and PAL formats can be accepted by the MX-2424. The MX-
2424 will automatically switch to the appropriate frame rate to match the incoming video sync format.
