The Radial Stage Bug SB-5 Laptop is a stereo direct box designed to easily integrate with laptop computers and other audio sources that employ a mini 3.5mm (1/8″ TRS) connector. It features an integral cable and storage cleat for easy deployment. inside, the passive design features two custom transformers that perform the balancing and impedance conversion. Transformer isolation benefits by eliminating hum and buzz caused by ground loops.

This makes the Stage Bug SB-5 an excellent choice for audio playback via PA systems, audio-visual integration and portable DJ setups.
