Dual Adjustable Video Attenuator-BNC

The RDL RU-VA2 is a dual adjustable video attenuator-BNC built around two 75 Ohm attenuation channels. Each channel is adjusted from the front panel, keeping routine level changes accessible after installation. Because the RU-VA2 is passive, it does not require power. Its compact one-third-rack format can operate as a standalone component or become part of a high-density rack installation, giving system designers considerable placement flexibility.

Ideal Use Cases

The RU-VA2 is suited to video systems that require attenuation across two channels with adjustments available directly from the front panel. Its standalone capability makes it appropriate where a dedicated rack position is unnecessary, while its one-third-rack construction supports organized, high-density equipment installations. The available mounting arrangements also accommodate systems installed on flat surfaces, panels, backboards, or inside cabinets.

This combination is especially relevant when a passive device is preferred. Since external power is not required, the attenuator can be incorporated without adding a power supply, voltage connection, or additional powered component to the system.

Why Choose This Model

The RU-VA2 brings two video attenuation channels into a single compact enclosure. Both channels use 75 Ohm attenuators, and level control is positioned on the front panel for straightforward access. The passive design simplifies power planning, while the range of optional mounting hardware allows the same model to support standalone, rack, surface, panel, backboard, and cabinet installations.

Its one-third-rack size is particularly useful when several compact devices must share rack space. The model can also remain outside a rack when the application calls for a localized or independently positioned attenuation control.

Installation and Integration

For rack installations, the RU-VA2 can be mounted using the optional RU-RA3 triple rack mount or an RC-1U rack chassis. Available adhesive strips support bottom mounting. The optional MB-2 bracket set permits bottom or top mounting to a flat surface, while the optional MB-1 mounting set supports front mounting to a panel or backboard. Cabinet mounting is available with the RU-BR1.

The case measures 1.7 inches high by 5.8 inches long by 2.0 inches deep, equivalent to 4.3 by 15.0 by 5.1 centimeters. Depth increases to 2.5 inches, or 6.4 centimeters, when the barrier block is included. These separate depth measurements help installers account for the complete assembly when planning equipment placement. The specified ambient operating environment is 20 degrees C to 60 degrees C.

The unit has a listed WEEE weight of 1.05 pounds and a shipping weight of 1.28 pounds. Package dimensions are 4.375 by 7 by 2.25 inches, and the package type is a cardboard box.

Performance Highlights

• Two channels of video attenuation in one enclosure
• 75 Ohm attenuators
• Front-panel level adjustment
• Passive operation with no power requirement
• Standalone or rack-mountable configuration
• One-third-rack design for high-density mounting

The design concentrates its stated functionality on manual video attenuation. Front-panel adjustment keeps the controls accessible, while passive operation removes the need to integrate the unit with a powered equipment connection.

What Makes It Different

The RU-VA2 is not limited to a single installation method. Its one-third-rack enclosure can be used independently, grouped in a compatible rack mount, secured to a flat surface, attached to a panel or backboard, or installed in a cabinet with the specified optional accessories. This flexibility allows one model to address several physical integration requirements without changing its core two-channel, 75 Ohm attenuation configuration.

Final Assessment

The RDL RU-VA2 is a focused choice for systems requiring two adjustable 75 Ohm video attenuation channels in a passive BNC-format device. Front-panel level control, one-third-rack construction, and extensive optional mounting choices support both standalone placement and structured equipment installations. For projects where power-free operation and adaptable physical integration are priorities, its published configuration provides a concise, clearly defined solution.
