The COBALT 6590 is a high-quality 10-bit analog to digital decoder for converting
525 and 625 line, analog composite, Y/C and component signals (YPbPr) to 270 Mb
4:2:2 SDI (SMPTE 259M-C) output with SMPTE EDH. The user can select four
different Y-C separation modes (4-line adaptive, 4-line non-adaptive, 3-line adaptive
and notch filter) for composite input and three different YPbPr inputs (BetaCam™,
MII™, or SMPTE/N10) for component inputs.
Features include auto-detection of input standard (NTSC/PAL/SECAM), differential
inputs, user configurable 75-ohm input termination and user input and output Proc.
gain controls. The user has a choice of direct clock output or de-jittered SDI output.
Color Bar test pattern and Pedestal On/Off functions are under user control via setup
switches accessible from the bottom of the 6590.

TERMINATION CONFIGURATION
Remove top cover and locate the three termination switches located next to each
BNC input. Moving the switch away from the BNC turns on 75 ohm termination.
Moving the switch towards the BNC removes the termination.
LED INDICATOR
The front panel LED indicates video lock when On and loss of video when blinking.
A dark LED indicates loss of power.
INPUT GAIN ADJUST
Set unit to Manual gain control (SW1-5). Apply 1V-video at all three inputs.
Remove covers and adjust RP1, RP2 and RP3 and RP4 for 1V gain at TP7, TP8,
RP9 & TP48. Under Proc Gain Adjustments, recall factory Proc. settings. Apply
test bars and confirm output signal with digital waveform monitor. Replace covers.
PROC. CONROL ADJUSTMENTS
Full control of Y-Gain, Y-Black level, Color Saturation and Hue can be User
controlled via internal switches. YPbPr has no hue control.
To set Proc. values set SW8 & SW7 as shown below and press UP or DWN.
To save settings set SW8 & SW7 to 9-9 and press UP or DWN.
To restore factory defaults set SW8 & SW7 to 8-8 and press UP or DWN.
To restore last user saved settings set SW8 & SW7 to 0-0 and press UP or DWN.
