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.
תכונות מפתח כוללות:
- רוחב פס גבוה: 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.
- עיצוב קומפקטי: Desktop size, with the option for side-by-side rack mounting in a 1U space using the RK–1 adapter (sold separately).

התקנה וחיבורים
Follow these steps to set up your Kramer VP-8K distribution ampחיים יותר:
- כיבוי מכשירים: Ensure all source devices (computers, media players) and display devices (monitors, projectors) are powered off before making any connections.
- חבר מקור קלט: Connect your computer graphics video source (e.g., PC, laptop) to the קֶלֶט 15-pin HD (F) connector on the rear panel of the VP-8K using a high-quality VGA/UXGA cable.
- חיבור צגי פלט: Connect up to eight display devices (e.g., monitors, projectors) to the פלט 1 בְּאֶמצָעוּת פלט 8 15-pin HD (F) connectors on the rear panel using high-quality VGA/UXGA cables.
- Set Sync Impedance: אתר את סנכרון מתג בפאנל האחורי.
- For video signals, set the switch to 75Ω.
- For computer graphics (TTL) signals, set the switch to Hi-Z (TTL).
- חבר חשמל: חברו את מתאם החשמל 5V DC המצורף ל 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.
- הפעלה של התקנים: Power on your display devices first, then power on your source device.
פֶּתֶק: For optimal performance, use Kramer high-resolution cables.
הוראות הפעלה
The Kramer VP-8K is designed for straightforward operation, primarily functioning as a plug-and-play distribution amplifier once connections are established.
- הפצת אותות: 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.
- תמיכה ברזולוציה: 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.
תַחזוּקָה
To ensure the longevity and optimal performance of your Kramer VP-8K, follow these maintenance guidelines:
- ניקוי: נתק את החשמל לפני הניקוי. השתמש במטלית רכה ויבשה כדי לנגב את החלק החיצוני של היחידה. אין להשתמש בחומרי ניקוי נוזליים או בתרסיס.
- אוורור: ודאו שיש אוורור נאות ביחידה. אין לחסום פתחי אוורור.
- סְבִיבָה: Operate the unit in a dry environment, away from direct sunlight, excessive heat, or moisture.
- ניהול כבלים: בדקו מעת לעת את כל חיבורי הכבלים כדי לוודא שהם מאובטחים וללא נזק.
