Tech Specs

Up-Conversion

• Hardware 10-bit

• Anamorphic: full-screen

• Pillar box 4:3: results in a 4:3 image in center of

screen with black sidebars

• Zoom 14:9: results in a 4:3 image zoomed slightly

to fill a 14:9 image with black side bars

• Zoom Letterbox: results in image zoomed to fill

full screen

• Zoom Wide: results in a combination of zoom and

horizontal stretch to fill a 16:9 screen; this setting

can introduce a small aspect ratio change

Downstream Keyer

• Supports graphics with alpha channel over video,

matte or framebuffer, or framebuffer content over

incoming video or matte.

Reference Input or LTC Input

• 1 x BNC assignable to Reference video or LTC input

Reference:

• Analog Color Black (1V) or Composite Sync (2 or 4V)

• Non-terminating

* These formats are dependent on specific software

functionality and are not normal ‘over-the-wire’ formats.

Video Output Digital

• 3G/SD/HD SDI, SMPTE-259/292/296/424

• Single Link 4:2:2 or 4:4:4 (1 x BNC)

• Dual Link HD 4:4:4, (2 x BNC)

• HDMI v1.4, 30/36 bits/pixel, RGB or YUV, 2.25Gbps

Audio Output Digital

• 16-channel, 24-bit SDI embedded audio,

48kHz sample rate, Synchronous

• 8-channel, 24-bit HDMI embedded audio,

48kHz sample rate, Synchronous

Audio Output Analog

• 8-channel, 24-bit D/A analog audio, 48kHz sample

rate, balanced (via 8 x XLR on DB-25 breakout

cable)

• +24 dBu Full Scale Digital (0 dBFS)

• +/- 0.2 dB 20Hz to 20kHz Frequency Response

Down-Conversion

• Hardware 10-bit

• Anamorphic: full-screen

• Letterbox: image is reduced with black top and

bottom added to image area with the aspect ratio

preserved

• Crop: image is cropped to fit new screen size

SD to SD Aspect Ratio

Conversion

• Letterbox: This transforms SD anamorphic material

to a letterboxed image

• H Crop: Will produce a horizontally stretched effect

on the image; transforms anamorphic SD to full

frame

• SD Pillarbox: Will produce an image in the center

of the screen with black borders on the left and

right sides and an anamorphized image in the

center

• V Crop: Will transform SD letterbox material to an

Machine Control

• RS-422, Sony 9-pin protocol (via breakout cable or

optional K3G-Box)

• 9-pin D-connector pinout is as follows:

1 GND

2 RX-

3 TX+

4 GND

5 No Connection

6 GND

7 RX+

8 TX-

9 GND

Shell GND

Physical

• Power: 10-20V, 18-22W

• Interface: Thunderbolt x 2
