3.0 CHECKING PACKAGE CONTENTS
Before attempting to use this unit, please check the packaging and make certain the
following items are contained in the shipping carton:
1x 1T-TBC or 1T-TBC-GL Time Base Corrector
1x 100-240VAC to 12VDC Power Adapter
1x Instruction Manual
NOTE: Please retain the original packing material should the need ever arise to return the unit. If you find any items are
missing, contact your reseller or tvONE immediately. Have the Model Number, Serial Number and Invoice available for
reference when you call.
4.0 CONNECTING THE HARDWARE
Please study the panel drawings below and become familiar with the signal input, outputs,
power requirements/inputs plus any controls present.
1T-TBC Multi-standard Time Base Corrector
1T-TBC-GL Multi-standard Time Base Corrector with Genlock
Connect the AC to +12 VDC adapter to an AC source and then to the DC power input
shown above.
NOTE: There is no power switch. The unit will begin to work as soon as you have the AC to +12 VDC adapter plugged in
and furnishing power.

Next connect an input cable and an output cable to either the Composite Video or
S-Video connectors. If the unit has power applied, it should begin to function as a Time
Base Corrector.
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:
Setting
Description
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.
NOTE: Pressing the Reset button toggles between automatic and manual selection of the desired standard. Although
you can manually select the standard, it is generally best to allow the unit to make the standard selection.
To force a manual input selection of the desired standard, make certain the System LED is
lighted, and then press the Reset button, which places the input selection in the Manual
mode. Next, press the DOWN arrow button to step through the various standards.
Pressing the Reset button a second time reverts back to automatic selection of the
standard.
5.3 Adjustment of Signal Parameters
Another user operation is the selection of a particular picture parameter you wish to
change. For instance: If you wish to adjust the amount of color in the picture, press the
Select button until the LED below the abbreviation “CLR” is flashing. Next press the UP
and Down Arrow buttons to either increase or decrease the amount of color in the picture.
Use the same procedure for Sharpness, Tint, Brightness and Contrast: Press the Select
button until you have reached the picture variable you wish to change and then use the
arrow buttons to make the actual adjustment.
5.4 Additional Reset Button Functions
Pressing the Reset Button while you have one of the adjustment parameters selected will
cause the 1T-TBC-GL or 1T-TBC to revert to the default setting for that parameter. If you
press and hold the Reset button for more than 3 seconds, ALL adjustment parameters will
be reset to their default settings.
5.5 Using the Genlock Capability (1T-TBC-GL Only)
The 1T-TBC-GL model has the ability to lock its output to a reference signal. This allows the
unit’s output to be used in a studio environment as an input to a video switcher or special
effects device requiring a timed video input source.
Additionally, the genlock capability also includes a loop through function. This allows one
genlock signal to be cascaded from one 1T-TBC-GL to another thereby providing multiple
timed video sources if needed. If you only intend to use a single 1T-TBC-GL, set the switch
on the back on the unit marked TERM 75to the “On”position. This will ensure that the
impedance of the genlock source is properly terminated. Similarly, if you cascade several
1T-TBC-GL genlock inputs using the loop through capability, also make certain you switch
the termination of the last unit to “On”.

6.0 TROUBLESHOOTING
Most problems with the 1T-TBC-GL and 1T-TBC units are related to misuse of the buttons
and signal adjustment controls. If you find that the picture is not acceptable, place the unit
in the automatic detection mode and then press and hold the Reset button for 3 seconds
to restore factory defaults. This should clear the problem. Another problem revolves
around the cables. Inspect the cables for loose connectors or cable damage such as
crushed cables or cables with cuts or nicks. Replace any cable exhibiting these problems.
You also must use the highest quality cables if you want to achieve the best results. Poor
quality cables will cause poor quality signals.
Note: It is strongly recommended that you use premium cables in order to achieve
maximum distance cable runs and the best performance possible.
After trying the above suggestions should the problem still persist, contact your dealer for
additional suggestions before contacting tvONE. Should the dealer’s technical personnel
be unable to assist you, contact tvONE via our support website:

team will respond within a short period of time.
