StageBug SB-5 Stereo Laptop Direct Box

Passive Stereo Direct Box For Laptops & Mobile Devices

The StageBug SB-5 is a compact stereo direct box designed to connect laptop computers, smartphones, tablets, or any mobile device to pro audio equipment and PA systems.

Stereo direct box for laptops, smartphones, and tablets

Cable with 3.5mm stereo plug to connect to mobile devices

Transformer isolation eliminates hum and buzz

Plug & play easy to use, no power required

Compact design fits in your laptop bag

The easy way to connect to the PA

The StageBug SB-5 provides an easy to use professional interface for connecting any mobile playback device to a mixer or PA system, with a built-in cable and 3.5mm stereo plug to connect directly to your laptop, smartphone, or tablet. Inside, a pair of custom wound transformers isolate the signals to prevent hum and buzz, and balance the audio to feed long cable runs without noise. Left and right 1/4" TRS outputs are provided for stereo operation, or a mono XLR output can be used to save channels on the PA system. The SB-5 works without any power required, and features additional ground lift and pad switches to eliminate ground loop noise and prevent distortion from high output audio sources.

SB-5 Specifications

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 3.6mm (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. Although remarkably compact and affordable, the SB-5 produces a exceptionally linear response with almost zero phase shift and less than 0.2% distortion at all frequencies. This makes the Stage Bug SB-5 an excellent choice for audio playback via PA systems, audio-visual integration and portable DJ setups.
