The Grass Valley LDK-4000 ELITE is a professional broadcast camera designed for high-end video production. The “Triax” designation refers to the type of cable it uses for signal transmission, which allows for a long-distance, reliable connection between the camera and the control equipment.

1. Camera System Overview

• Type: Studio/Field camera
• Camera Head: LDK-4000 ELITE
• Transmission: Triax-based transmission, offering long-distance signal transfer
• Format: HD/SD (supports both High Definition and Standard Definition video production)
• Resolution: Supports resolutions up to 1920 x 1080 (Full HD)
• Sensor: 2/3-inch CMOS sensors (providing high sensitivity and low noise)
• Frame Rate: Typically supports 50Hz/60Hz and can handle frame rates up to 1080p at 50/60 fps

2. Optics

• Lens Mount: 2/3-inch bayonet lens mount (for professional lenses)
• Zoom Lens Compatibility: Works with industry-standard zoom lenses.
• Imaging Technology: CMOS (Complementary Metal-Oxide-Semiconductor) sensors for improved performance in low-light conditions and wider dynamic range.

3. Signal Transmission

• Triax Cable: Used for long-distance connections, the Triax allows for video, audio, and control signals to be transmitted over long distances (up to 1,000 meters or more with proper equipment).
• Triax to Fiber Conversion: Supports optional conversion from Triax to fiber-optic transmission for even longer cable runs.

4. Video Signal Processing

• Resolution Options: Supports up to 1080i, 1080p, and 720p.
• Color Processing: Full 4:2:2 color space, high-quality color reproduction.
• Dynamic Range: High dynamic range (HDR) capability with a wide range of exposure.

5. Control and Interface

• Camera Control Unit (CCU): The camera is typically paired with a CCU, such as the Grass Valley CCU-4000, for remote control of camera functions like gain, white balance, and zoom.
• Control Interface: Supports full remote control via Triax cable for functions like iris, gain, and focus.
• Intercom: Full integration with intercom systems for communication between the operator and production crew.

6. Audio

• Audio Channels: The camera supports multiple audio channels for embedded audio signals, typically in 16-bit or 24-bit resolution.
• Microphone Input: XLR connectors for professional audio input.

7. Features

• HD/SD Switchable: The camera can be used in both HD and SD formats, making it versatile for different broadcasting needs.
• Multi-Format Compatibility: Compatible with various broadcast standards (e.g., NTSC, PAL).
• High Sensitivity: Improved low-light sensitivity, which is ideal for indoor and low-light shooting environments.
• Advanced Colorimetry: Advanced algorithms for color correction and dynamic range adjustment.
• Electronic Shutter: Electronic shutter with variable settings for specific shooting conditions.

8. Power

• Power Supply: The camera typically runs on DC 12V power through a Triax cable connection or can be powered from the CCU.
• Power Consumption: Varies depending on the specific setup, but generally low power consumption for a high-end professional camera.

9. Dimensions and Weight

• Camera Dimensions: Approximately 9.6 x 9.4 x 14.2 inches (243 x 239 x 360 mm)
• Weight: Around 6.5 kg (14.3 lbs), depending on configuration.

10. Additional Features

• Flexible Mounting Options: Can be mounted on tripods or other rigs.
• Advanced Focus Assist: Includes tools for assisting with focus, such as peaking or digital zoom features.
• Adjustable Color Temperature: For achieving optimal lighting conditions on set.
• Multi-format Outputs: Supports SDI, HD-SDI, and other professional video output formats.

11. Applications

• Live Event Production: Commonly used for sports, concerts, and other live broadcast events.
• Studio Production: Suitable for high-quality broadcast studios with multiple cameras.
• Outside Broadcast: With the Triax connection, it’s highly suitable for outdoor productions.

12. Optional Accessories

• Camera Control Panel (CCP): For more intuitive operation of the camera settings.
• Fiber Optic Interface: For long-distance fiber optic transmission, extending the range of Triax even further.

The LDK-4000 ELITE Triax system is engineered to meet the demanding needs of professional broadcasters, offering both flexibility and high-quality output for various types of live and studio productions.
