A DI for Computer Audio Output

Need to pump the audio output of your laptop through the PA, cleanly? Sweetwater has the device you need: the Radial StageBug SB-5. The StageBug SB-5 is a passive DI that takes an unbalanced stereo signal and sends it through a pair of custom-wound transformers, which balances the signal for cable runs of up to 300 feet. The transformers also isolate the source device - your computer, for instance - from the PA system, to eliminate buzz and hum due to ground loops. The unit is also fitted with a ground-lift switch.

Flexible I/O to handle any scenario

Input is via a permanently attached 5-foot, 1/8" stereo TRS cable. For output connections, you have a choice of two 1/4" TRS jacks for stereo operation or an XLR that automatically sums to mono. A 15dB pad lets you knock down hot input signals. Whether you're an AV technician or touring musician with a computer, the Radial StageBug SB-5 is a must-have tool.

Radial StageBug SB-5 Direct Box Features:
  • Stereo direct box optimized for consumer device audio
    • Ideal for computers, tablets, etc.
  • Permanently attached 5' input cable with 1/8" stereo TRS
    • Stows conveniently on sidewinder cleat
  • 2 x 1/4" TRS output jacks for stereo operation
    • XLR output automatically sums to mono
  • Custom-wound transformers balance signal for long cable runs up to 300'
    • Transformers eliminate buzz and hum due to ground loops
  • 15dB pad lets you knock down hot input signals
  • Passive DI; requires no power
Plug your computer's audio output into the Radial StageBug SB-5!

Fix our problems

We had a buzz coming from the computer we played music on due to a grounding issue. There would be sound coming when the computer was on or off, and you could hear the sound change when other things got plugged in or unplugged. My S.E. recommended this to fix the issue, and we have had no issues since.

Great DI - solves the problem of 3.5mm output from keyboards

Just wanted to add my recommendation of this great sounding DI from Radial. But I also wanted to point out that's it's just not for computer audio. I recently bought a Casio SDP-S350 keyboard - it has a ton (700+) of great sounds and a very responsive key-bed. But the one big drawback is that the only output is a 3.5mm stereo plug. Usually, this would be a deal breaker if you needed a "giggable" keyboard, but the Stagebug SB-5 solves this problem. I use the XLR output to feed the PA system (or recording console) and I use the 1/4" outputs to simultaneously feed my powered monitor. Problem solved. Another great product from Radia.
