Radial Engineering StageBug SB-5 Compact Stereo Laptop Direct Box

The Radial Engineering StageBug SB-5 is a compact & portable stereo direct box designed to accommodate laptop computers, tablets, and other consumer audio products when amplifying the signal through a PA system.

The StageBug SB-5 provides an easy-to-use professional interface for connecting any mobile playback device to a mixer or PA system, with a built-in cable and 3.5mm stereo plug to connect directly to your laptop, smartphone, or tablet. Inside, a pair of custom wound transformers isolate the signals to prevent hum and buzz, and balance the audio to feed long cable runs without noise. Left and right 1/4" TRS outputs are provided for stereo operation, or a mono XLR output can be used to save channels on the PA system. The SB-5 works without any power required, and features additional ground lift and pad switches to eliminate ground loop noise and prevent distortion from high output audio sources.
