7600 SD/HD/MHD-REF — Instruction Manual 25
Installation
AES audio may also be accessed through the unbalanced AES 1 and AES 2
BNCs when they are present. This requires the GPS function with the 7600
MHD-REF model. See
GPS Setup (7600 MHD-REF) on page 52 .
LTC Output (7600 MHD-REF Model)
The LTC (Longitudinal Timecode) 9 pin Sub-D female connector provides
LTC 1 and LTC 2 outputs with the 7600 MHD-REF model. The LTC function
provides the following:
• Two outputs of LTC
• Vertical Interval Timecode (VITC) superimposed on analog waveforms.
This is enabled or disabled in accordance with the current group
arrangement of the analog signal outputs.
• SDI outputs (see HD/SD SDI Test Outputs on page 20 ) will offer a com-
bination of Digital VITC (SMPTE S266) for standard definition signals
only and ATC (SMPTE RP188) for standard definition or high definition
SD signals.
The pinouts and their functions for this connector are shown in Table 3 .
Configuration is done from the Setup/LTC menu. Refer to Timecode Func-
tionality (7600 MHD-REF) on page 58 .
