Indledning
The Kramer VP-8K is a high-performance distribution amplifier designed for computer graphics video signals, supporting resolutions up to and exceeding UXGA. This device efficiently takes a single input signal, buffers and isolates it, and then distributes it to eight identical outputs. It is engineered for reliable signal distribution in various professional audio-visual environments.
Nøglefunktioner omfatter:
- Høj båndbredde: 370MHz (–3dB) for clear signal transmission.
- HDTV Compatible: Supports high-definition television signals.
- Selectable Sync Input Impedance: Options for 75ohm (video) and 510ohm (Graphics/TTL).
- Kr–isp Advanced Sync Processing: A proprietary technology that ensures compatibility with a wide range of computers by restoring the sync signal waveform, even if the original sync level is low. This feature can be enabled or disabled as needed.
- Kompakt design: Desktop size, with the option for side-by-side rack mounting in a 1U space using the RK–1 adapter (sold separately).

Opsætning og forbindelser
Follow these steps to set up your Kramer VP-8K distribution amplivligere:
- Sluk for enheder: Ensure all source devices (computers, media players) and display devices (monitors, projectors) are powered off before making any connections.
- Tilslut inputkilde: Connect your computer graphics video source (e.g., PC, laptop) to the INPUT 15-pin HD (F) connector on the rear panel of the VP-8K using a high-quality VGA/UXGA cable.
- Connect Output Displays: Connect up to eight display devices (e.g., monitors, projectors) to the UDGANG 1 ved UDGANG 8 15-pin HD (F) connectors on the rear panel using high-quality VGA/UXGA cables.
- Set Sync Impedance: Find SYNC tænd/sluk-knappen på bagpanelet.
- For video signals, set the switch to 75Ω.
- For computer graphics (TTL) signals, set the switch to Hi-Z (TTL).
- Tilslut strøm: Connect the supplied 5V DC power adapter to the 5V DC input jack on the rear panel of the VP-8K. Plug the power adapter into a suitable electrical outlet. The power indicator on the front panel should illuminate.
- Tænd enheder: Power on your display devices first, then power on your source device.
Note: For optimal performance, use Kramer high-resolution cables.
Betjeningsvejledning
The Kramer VP-8K is designed for straightforward operation, primarily functioning as a plug-and-play distribution amplifier once connections are established.
- Signalfordeling: Once powered on and connected, the VP-8K automatically distributes the input computer graphics video signal to all eight connected output displays simultaneously.
- Kr–isp Advanced Sync Processing: This feature is typically enabled by default to ensure maximum compatibility. If you experience sync issues with a particular source, you may try disabling this feature (if an external switch or setting is available, though for VP-8K it's internal and automatic). The primary function is to restore weak sync signals.
- Opløsningssupport: The unit supports resolutions up to and exceeding UXGA. Ensure your source and display devices are configured to compatible resolutions.
No user intervention is typically required beyond initial setup and power cycling.
Opretholdelse
To ensure the longevity and optimal performance of your Kramer VP-8K, follow these maintenance guidelines:
- Rensning: Disconnect power before cleaning. Use a soft, dry cloth to wipe the exterior of the unit. Do not use liquid or aerosol cleaners.
- Ventilation: Ensure the unit has adequate ventilation. Do not block any ventilation openings.
- Miljø: Operate the unit in a dry environment, away from direct sunlight, excessive heat, or moisture.
- Kabelstyring: Kontrollér regelmæssigt alle kabelforbindelser for at sikre, at de er fastgjorte og fri for skader.
