Radial Engineering StageBug SB-5

The StageBug SB-5 is a compact stereo direct box designed to connect laptop computers, smartphones, tablets, or any mobile device to pro audio equipment and PA systems.

It has an easy-to-use professional interface, using a built-in cable and 3.5mm stereo plug to connect any mobile playback device (like your laptop, smartphone, or tablet) to a mixer or PA system. 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. It provides the option of stereo or mono output; two 1/4" TRS output send separate left and right signals while the XLR out give you a mono signal for saving room on your mixer. 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.
