The Radial Stage Bug SB-5 is a compact stereo direct box designed to accommodate laptop computers, tablets and other consumer audio products when amplifying the signal through a PA system.
The passive design begins with an integrated input cable that connects from the headphone out via a flexible 1.5m (5') cable that is terminated with a standard 3.5mm (1/8") stereo connector. The cable is secured via a clamping strain relief and is wrapped using the sidewinder cleat for easy storage. This of course eliminates having to locate a cable making it easier to deploy in fast paced work environments. Inside, 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.

Great toolbox item
Great little box. I love the small size, affordable price & built in cable. I use it mainly with an iPad & it's size & cable really helps reduce clutter in my setup.
If I needed sound from a laptop instead of a tablet I think I'd choose the Radial JPC with it's active buffer (in case of a noisy computer). Lire plus
I also think I'll eventually also get a ProAV1 or ProAV2 just to have as toolbox items. But, for anything with a 3.5mm port, I'll probably reach for the SB-5 first because it's so small and convenient.
