Kramer 1:5 Composite Video Distribution Amplifier (105VB)

The Kramer 105VB 1:5 Composite Video Distribution Amplifier is a purpose-built solution for professional AV installations that demand pristine video distribution from a single source to multiple destinations. This compact, high-performance device delivers correct buffering and isolation, ensuring that each of the five outputs receives a faithful, impedance-matched copy of the input signal. With a broad bandwidth of 400 MHz (-3 dB), the 105VB preserves luminance, color, and detail across runs that would challenge lesser amplifiers, making it ideal for classrooms, boardrooms, control rooms, broadcast environments, digital signage networks, and multimedia studios. The unit is designed to integrate seamlessly into existing video chains, reducing signal degradation, minimizing crosstalk, and simplifying complex AV setups. Its front-panel level (gain) control provides flexible adjustment to match downstream displays and processing gear, enabling consistent performance even when combining legacy CRT displays with modern flat panels. Built on Kramer’s trusted engineering heritage, the 105VB combines reliability with ease of installation, delivering professional-quality distribution without complicating your signal path.

• Five identical outputs with proactive buffering and isolation. The 105VB takes a single composite video input and distributes it to five destinations while preserving signal integrity. Each output is buffered to prevent loading effects on the source and to maintain consistent amplitude across all connected displays. This design minimizes crosstalk and ensures uniform brightness and color across every monitor, projector, or processing device in your chain.
• High bandwidth for pristine video across multiple destinations. With a bandwidth of 400 MHz (-3 dB), the 105VB supports clean, high-fidelity composite video even when long cable runs and multiple taps are involved. This bandwidth headroom helps preserve crisp edges, accurate luma/chroma balance, and smooth motion, delivering a visually consistent experience whether you’re presenting, teaching, or monitoring feeds in a control room.
• Gain control for flexible, optimized signal levels. The integrated Level (Gain) control lets you tailor the output level to match the needs of downstream equipment, from displays with lower input sensitivity to video processors with strict input thresholds. This flexibility helps prevent signal clipping, reduces the risk of overload on distant displays, and ensures consistent image quality across all outputs—even when the input source varies or when cable losses differ between runs.
• Versatile connectors adapted to common AV layouts. The 105VB features BNC connectors for standard composite video installations, providing robust, locking-style connections that are common in professional setups. Note that the 105V variant uses RCA connectors, offering a convenient option for environments that rely on RCA wiring. This connector versatility makes the 105VB suitable for integration into existing infrastructure without requiring major rewiring or adapters, streamlining deployment in classrooms, conference rooms, and broadcast suites.
• Compact, reliable Kramer TOOL design built for professional use. The 105VB’s compact form factor fits easily into rack-mounted or shelf-based installations, helping you maximize space in equipment rooms and AV closets. Designed to withstand daily use in demanding environments, the device delivers stable performance with minimal thermal and electrical interference, ensuring dependable operation during meetings, lectures, or live broadcasts. Its straightforward layout promotes quick setup, easy servicing, and scalable expansion when you need to grow your video distribution network.

how to install Kramer 1:5 Composite Video Distribution Amplifier

Begin by locating a suitable power source and a secure mounting area for the 105VB. Connect your composite video source to the single input using a standard coaxial cable with the appropriate connector for your variant (BNC for the 105VB, RCA if using the 105V version). Next, connect each of the five outputs to your displays, projectors, or video processing devices using identical coaxial cables and matching connector types. Verify that all outputs are terminated properly and that cable lengths are within the device’s design tolerance to maintain signal integrity. If needed, adjust the Level (Gain) control on the front panel to optimize the signal level for downstream equipment; this is especially useful when distributing to displays with differing input sensitivities or when cable losses vary significantly between branches. After wiring, power the unit and confirm that each output delivers a clean, synchronized video signal. Finally, secure the amplifier in a rack or shelf, organize the cables to prevent strain, and test the entire chain by sending the same test pattern to each output to ensure uniform brightness, color, and focus across all destinations.
