Transformer isolated eliminates noise
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.
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
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
