Description
Download Manual The EZ-VDA3BX is a compact composite video distribution amplifier designed to accept a single composite input and deliver three identical composite outputs. It preserves video integrity while providing level and equalization adjustments at the front panel – enabling signal restoration when driving long coaxial runs. The unit operates with both NTSC and PAL color standards to support worldwide formats.
Key features include gold-plated BNC connectors, front-panel GAIN and EQ trimmers, and a 75 ohm terminated input to maintain correct impedance matching. The amplifier offers adjustable gain from unity to +6 dB and adjustable equalization to compensate cable attenuation. A wide bandwidth greater than 400 MHz supports high quality video and low signal distortion.
Performance metrics include differential gain and phase well below common thresholds and very low residual noise levels. Differential gain is specified at less than 0.1 percent and differential phase at less than 0.1 degree – values that help preserve color fidelity. Residual noise is specified at less than -90 dB referenced to 1 V p-p, indicating a clean noise floor for sensitive video signals.
Connectivity is implemented using professional gold-plated BNC jacks for both input and outputs, with outputs source-terminated at 75 ohm and nominal 1 V p-p levels. The front-panel trimmers make it straightforward to tune gain and equalization when connecting long coax runs of 100 to 1000 feet. The EZ-VDA3BX supports standard composite cabling and integrates easily into existing analog video installations.
Typical applications include in-store video distribution, houses of worship, restaurants, clubs, security monitoring systems, and commercial audio/video setups. The small footprint and 1/6 rack width mounting size make it an unobtrusive addition to equipment racks or AV furniture. It is well suited to installations where multiple displays or recorders must receive the same composite feed while maintaining picture clarity.
Installation is straightforward with a single 24 Vdc power input and minimal power consumption. The robust metal enclosure and professional connectors deliver reliable day-to-day operation in commercial environments – while front-panel adjustments allow technicians to optimize picture quality on site. The EZ-VDA3BX provides a compact, practical solution for distributing composite video with precise control over gain and equalization.
