The Radial SB5W is a stereo direct box made to fit in a standard single-gang electrical wall plate. This provides the AV integrator with a simple, yet effective means of connecting an unbalanced analog audio source such as the headphone output from a laptop computer, iPhone, tablet or line level source such as a CD player to a balanced audio system via a permanently mounted interface.

The design begins with all-steel construction for maximum durability and a fully shielded back box to help eliminate pollution from electromagnetic fields caused by dimmers, ballasts, power cables and transformers. Front panel 3.5mm TRS and RCA connectors provide a standard interface for any stereo source and a fully variable level control makes volume adjustments easy. Inside, the SB5W employs two great sounding transformers to convert the high impedance signal to a balanced low impedance capable of driving cables upwards to 100 meters (300') without noise. Transformers further benefit by eliminating hum and buzz caused by so-called ground loops and stray DC voltages that are common when interfacing consumer grade audio devices with professional audio systems. This is augmented with a set & forget ground lift switch. Should channel count be a problem, a recessed mono switch passively sums the stereo signal to a single output. The outputs feature screw terminals with tie-down points for tie-wraps to make installation fast, efficient and permanent.

Finished in a durable black powder coat and sized to fit a standard Decora wall plate, the Radial SB5W looks sharp with any color faceplate while providing clear labeling for easy manipulation for the pros and novices alike.

The Radial SB5W Wall plate DI... a world-class connectivity solution by Radial.
