CONNECTING THE TIMECODE READERS
INSTALLATION
The video output from the telecine should be connected to the GEN VIDEO
IN Loop even if the VITC generator is not being used. (See Section 2.6)
Program video with VITC is available on 2 identical video outputs. The
VITC1 and VITC2 LINES items on the TIMECODE menu are used to select
the lines you wish to record VITC on.
information then VITC 1 lines. (See section 3.3.2)
When using KeyKode / edge number information in the user bits of VITC, the
time code generator built into the VTR should be set to the "EXTERNAL
DIRECT" mode of operation.
understand the counting sequences of the encoded data, and will introduce
delays and possibly errors in the user bit data if it attempts to regenerate the
timecode before recording it on tape. (See section 3.9.1)
2.7.2. Connecting the LTC Generator
The generator LTC output is available on an XLR connector at the rear
panel. The output level of the generator is factory set to 1 volt peak to
peak, but may be adjusted using the level adjustment (labelled VR3)
located near the rear of the 615 (center) module, on the bottom circuit card.
The generator code output should be connected to the record input of the
time code channel or audio track 2 of your video recorder. (Audio track 3
for 1" VTR's) Pin 1 of the XLR is ground, and pins 2 and 3 provide a
balanced output. When using a machine with an unbalanced input the
signal should be connected to Pin 3 of the generator output XLR. Pin 2
should be left open. The GEN ASSIGN item of the TIMECODE menu is
used to set up the operational mode of the LTC and VITC generators. (See
section 3.3.1)
When using KeyKode / edge number information in the user bits of LTC, the
time code generator built into the VTR should be set to the "EXTERNAL
DIRECT" mode of operation.
understand the counting sequences of the encoded data, and will introduce
delays and possibly errors in the user bit data if it attempts to regenerate the
timecode before recording it on tape. (See section 3.9.1)
