Description

The Radial StageBug SB-5W is a wall-mountable passive stereo direct box designed specifically for installed audio systems in commercial or professional settings. Built to fit a standard North American single-gang electrical wall plate, it serves as a clean, discreet interface between consumer-grade audio devices-like laptops, smartphones, tablets, or CD players-and professional balanced audio systems. It's particularly well-suited for AV integrators and contractors looking for a reliable, easy-to-install solution that doesn't require external power.

Equipped with both 3.5mm TRS and RCA stereo inputs, the SB-5W offers plug-and-play connectivity for a variety of devices. When a 3.5mm cable is connected, it overrides the RCA inputs for convenience. The front panel features a level control knob to adjust input volume, and internal features like transformer isolation, a ground lift, and a mono sum switch ensure a clean, noise-free signal. Outputs are made via balanced screw terminals, allowing the signal to travel long distances without degradation. Thanks to its passive design and rugged metal construction, the SB-5W is an ideal choice for permanent AV installations in classrooms, boardrooms, houses of worship, or hospitality environments where simplicity, durability, and audio clarity are key.

Features

Wall-Mount Design: Installs in a standard wall plate for clean and permanent integration.

Stereo to Balanced Output: Converts unbalanced stereo signals into balanced mic-level signals for long cable runs.

Multiple Input Options: Accepts audio from 3.5mm or RCA inputs to connect phones, laptops, tablets, or media players.

Automatic Input Switching: Plugging into the 3.5mm jack disables the RCA inputs to avoid signal conflict.

Level Control: Front panel knob allows easy volume adjustments right at the wall plate.

Mono Summing Option: Combines stereo channels into mono for simple PA system connections.

Ground Lift Switch: Helps eliminate hum and buzz caused by ground loops.

Transformer Isolation: Prevents noise interference by isolating the audio signal.

Passive Operation: No power supply required for operation.

Installer-Friendly Outputs: Screw-down terminals simplify permanent wiring in installations.

Durable Construction: Built with a steel chassis for reliability in commercial or public settings.
