The StageBug 5 is a compact stereo DI box designed to amplify consumer audio from computers, tablets and smartphones without introducing unwanted noise and hiss that can plague the sound at higher levels
The passive design has a universal 3.5mm(1/8") jack cable that plugs directly into the headphone out of your Mac, PC, laptop or mobile device. This cable can be stowed tightly away with the side winding cleat.
Here's what radial say about the SB-5
The signal is sent to a pair of custom wound transformers where the impedance is lowered and the signal is balanced for long cable runs - upwards to 100 meters (300'). Transformers further benefit by isolating the computer from the PA system to help eliminate hum and buzz caused by ground loops. This is augmented with a ground lift switch to further reduce ground contamination.
A choice of output connectors is available including a stereo set of ¼" TRS jacks for full stereo operation or an XLR out that automatically sums the left-right program material to mono. This can save valuable channels on the PA system and makes setup easier in situations where full stereo reproduction is not required. A -15dB input pad may be engaged to reduce sensitivity and enable extra high output sources to be connected without distortion.
These features combine to make the SB-5 the perfect tool-kit DI for the AV technician, media manager or traveling musician equipped with a computer.
