The easy way to connect to the PA
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.

FEATURES

Input Cable
Connecting to the SB-5 is done with an integral 1.5 meter (5ft) cable terminated with a 3.5mm (1/8”) TRS connector. Attached to ensure cable is not lost when stored. 

1/4" TRS Out
Set of connectors are balanced TRS for standard mic level output.

Pad
Reduces the input sensitivity by 15dB for louder sources.

XLR Out
Summed mono output combines the left and right inputs to save valuable mixer channels.

Strain Relief
Retains the integral cable to ensure pulling it will not harm the internal circuit board and solder connection.

Lift
Used to help eliminate hum and buzz caused by ground loops.
