5.0 OPERATING THE UNIT
The 1T-TBC-GL and 1T-TBC Time Base Converters are identical with the exception of
a genlock provision in the 1T-TBC-GL version. (A discussion of the genlock capability is
contained in section 5.7 below).
The 1T-TBC-GL and 1T-TBC are operated via selection buttons referenced to indicator
LEDs.
Please refer to the drawing below for the discussion that follows.
5.1 Initial Power Up
When power is applied to the unit, it will default to the auto detect mode and also select
the proper Television Standard. The letters on the panel above the bottom row of LEDS
will indicate the standard selected:
A Auto-Detect TV Standard
S SECAM Standard
PN PAL-N
PM PAL-M
P PAL
N4 NTSC 4.43 Mhz
N NTSC 3.58 Mhz
S Select System Mode
As an example of how the auto-detect works, if you live in the United States or Japan,
the standard will be the NTSC 3.58 and the unit will light the “A” LED plus the “N” LED.
In the United Kingdom, the standard will be PAL so the “A” LED will light as well as the
“P” LED. Finally, in France, the “A” and “S” (for SECAM) LEDs will light.
5.2 System Button Function
If you press the Select button until the System LED is illuminated on the top row, you
can gain access to the bottom row of functions. You can then either automatically or
manually select the input Television Standard you wish to use.
