3. INSTALLATION

Connect one end of a DB15 cable to the TBC 2. Connect the other end of the cable to the DB 15
on the VTR to be controlled. Identified as “TBC Remote” or “External Control.” Because the
TBC Remote connector has power on its pins, cabling should be done only with the VTR power
switch turned off. Once the TBC 2 panel is securely connected to the VTR, power may be safely
turned on.

Installation is complete.

4. ADJUSTMENTS

Each control is clearly labeled as to its function. Each control may be adjusted over a wide range.
Each control may be switched in or out by using the toggle switch located below the control. The
out position set that function to unity gain, that is, as set within the VTR. The in position enables
the associated control.

Video (SetUp) Level Adjust to eliminate any deviation

Video Level Adjust to 100 IRE.

Chroma Level Adjust so that the specified level is obtain ed.

Hue Adjust so that the vector waveform meets the VTR specifications.

5. H SYNC AND SUBCARRIER ADJUSTMENTS

These controls are inset screwdriver adjustments. These adjustments are best made using a
waveform/vectorscope and good video alignment practice by trained personnel only. Consult
the VTR operator/s or service manual for the correct procedure.
