Introducció
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.
Les característiques clau inclouen:
- Amplada de banda alta: 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.
- Disseny compacte: Desktop size, with the option for side-by-side rack mounting in a 1U space using the RK–1 adapter (sold separately).

Configuració i connexions
Follow these steps to set up your Kramer VP-8K distribution ampmés viu:
- Apagueu els dispositius: Ensure all source devices (computers, media players) and display devices (monitors, projectors) are powered off before making any connections.
- Font d'entrada de connexió: Connect your computer graphics video source (e.g., PC, laptop) to the ENTRADA 15-pin HD (F) connector on the rear panel of the VP-8K using a high-quality VGA/UXGA cable.
- Connecta les pantalles de sortida: Connect up to eight display devices (e.g., monitors, projectors) to the SORTIDA 1 a través de SORTIDA 8 15-pin HD (F) connectors on the rear panel using high-quality VGA/UXGA cables.
- Set Sync Impedance: Localitza el SYNC switch on the rear panel.
- For video signals, set the switch to 75Ω.
- For computer graphics (TTL) signals, set the switch to Hi-Z (TTL).
- Connectar l'alimentació: 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.
- Dispositius d'encesa: Engegueu primer els dispositius de visualització i després el dispositiu font.

Instruccions de funcionament
The Kramer VP-8K is designed for straightforward operation, primarily functioning as a plug-and-play distribution amplifier once connections are established.
- Distribució del senyal: 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.
- Suport a la resolució: 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.
Manteniment
To ensure the longevity and optimal performance of your Kramer VP-8K, follow these maintenance guidelines:
- Neteja: Disconnect power before cleaning. Use a soft, dry cloth to wipe the exterior of the unit. Do not use liquid or aerosol cleaners.
