Video Distribution Amplifier-1X2 BNC NTSC/PAL

The RDL EZ-VDA2B is a compact 1×2 video distribution amplifier that routes one composite video input to two composite outputs. Designed for NTSC or PAL signals, it combines professional gold-plated BNC connections with adjustable front-panel gain and equalization. Its bandwidth exceeds 400 MHz, while its 1/6-rack-width format and 2.9-inch by 3-inch case provide substantial video performance in a small enclosure.

Ideal Use Cases

This model is suited to systems that need to send a single composite video signal to two destinations. The 75 Ω input accepts a nominal 1 V p-p signal through a BNC jack, while two source-terminated 75 Ω BNC outputs each provide a nominal 1 V p-p signal when terminated. Support for both NTSC and PAL makes the EZ-VDA2B applicable to either signal standard without requiring separate distribution models.

The compact case is especially useful where installation space is limited. Its 1/6-rack-width mounting size allows the amplifier to provide two-output distribution without occupying the space associated with a wider component.

Why Choose This Model

The EZ-VDA2B provides direct control over two important signal parameters. Its front-panel GAIN trimmer offers adjustment from unity to +6 dB, while the EQ trimmer provides equalization from flat to +7 dB at 50 MHz. These accessible adjustments allow the amplifier to be configured for the connected video path without opening the enclosure.

Gold-plated professional BNC jacks are used for the input and both outputs. The input is terminated at 75 Ω, and each output is 75 Ω source-terminated. This clearly defined connection arrangement makes the unit straightforward to integrate into systems using BNC-based composite video cabling.

Installation and Integration

Integration begins with one composite source connected to the input BNC jack and up to two composite destinations connected to the output BNC jacks. The input level is specified at 1 V p-p nominal, and each output is specified at 1 V p-p nominal when terminated. AC coupling is used throughout the amplifier.

The unit operates from 24 Vdc and draws 20 mA while idle or up to 30 mA maximum. The listed included power-supply options are the PS-24AS for the USA and the PS-24AX for international use. The case measures 2.9 inches wide by 3 inches deep, equivalent to 7.4 cm by 7.6 cm, and uses a 1/6-rack-width mounting size.

Performance Highlights

With bandwidth greater than 400 MHz, the EZ-VDA2B supports high-quality video distribution while retaining a compact physical footprint. Adjustable gain covers unity through +6 dB, and adjustable equalization ranges from flat to +7 dB at 50 MHz.

Differential gain is specified at less than 0.1%, and differential phase is less than 0.1 degree. Residual noise is below -90 dB when referenced to a 1 V p-p signal. Together, these specifications define the amplifier’s handling of composite video signals and provide concrete performance criteria for evaluating it within a video system.

What Makes It Different

The EZ-VDA2B combines one-input, two-output composite distribution with user-adjustable front-panel controls in a small amplifier. Its combination of greater than 400 MHz bandwidth, less than 0.1% differential gain, less than 0.1-degree differential phase, and residual noise below -90 dB distinguishes it through measurable video performance.

Rather than providing fixed amplification alone, the unit includes both gain and high-frequency equalization adjustments. The use of gold-plated BNC jacks across all signal connections further supports its professional connection format.

Final Assessment

The RDL EZ-VDA2B is a focused solution for distributing one NTSC or PAL composite input to two BNC outputs. It offers adjustable gain and equalization, 75 Ω signal connections, AC coupling, and bandwidth greater than 400 MHz in a 1/6-rack-width enclosure. For installations requiring compact two-way composite video distribution with documented signal-performance specifications, it delivers a clearly defined combination of connectivity, adjustment, and size.
