Radial Engineering StageBug SB 5 Laptop DI Radial

Stereo direct box for laptop computer Integral 1.5m cable with sidewinder cleat Transformer isolation eliminates noise Plug & play easy to use – no power required 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 1/4 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.
