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.
