Radial StageBug SB5 Passive Stereo Direct Box for Laptops & Mobile Devices

Connect your mobile devices to professional audio systems with confidence using the StageBug SB-5, a compact stereo direct box engineered specifically for laptops, smartphones, tablets, and other portable audio sources. This professional-grade interface bridges the gap between consumer electronics and pro audio equipment, making it an essential tool for musicians, DJs, and audio professionals who need reliable connectivity on stage or in the studio.

At the heart of the SB-5 are custom wound transformers that provide complete signal isolation, effectively eliminating hum and buzz that can plague direct connections.

This thoughtful design makes setup quick and straightforward, allowing you to focus on your performance rather than troubleshooting connections. The compact form factor ensures it won’t take up valuable space in your equipment bag while still providing the robust performance expected from professional audio gear.
