Overview
The COBALT 8090 is a high-quality 12-bit analog to digital converter/decoder for converting
HD and SD analog signals into the corresponding SMPTE 292/259M-C serial digital signals.
The 8090 has three differential BNC inputs that support both analog HD in YPbPr or GBR (tri or
bi level sync) and analog SD composite, Y/C and component signals (YPbPr/GBR). For SD
inputs, the 8090 features a 5-line adaptive comb with presets for SD component BetaCam™,
MII™, SMPTE/N10 and GBR. The input standard is automatically detected, but input signal
type for HD (YPbPr /RGB) and SD (Composite, Y/C, Component) must be pre-selected by the
user via external switch settings.
Supported Formats
HD 1080 i, p, sF 23.98, 24, 25, 29.97, 30, 50, 59.94, 60
HD 720p 25, 29.97, 30, 50, 59.94, 60
SD 525, 625 59.94, 50
LED Indicator
The LED indicates video lock when On and loss of video when blinking. A dark LED indicates
loss of power. The LED can be set to indicate signal standard (see rotary switch settings)
Video Processing (Proc.) Control Adjustments
Full digital control of Y-gain, Y-black level, color saturation and hue can be user controlled by
internal rotary switches. Remove the bottom cover and locate S5, S6, S7, S8.
To set Proc. values set S5 & S6 as shown below and press UP or DWN (S4, S3).
To save settings set S5 & S6 to 9-9 and press UP or DWN.
To restore factory defaults set S5 & S6 to 8-8 and press UP or DWN.
To restore last user saved settings set S5 & S6 to 0-0 and press UP or DWN.
