Techopedia Explains Breakout Box

The many uses for breakout boxes include:

  • Docking stations
  • Electronic control units (ECUs)
  • Electronic test equipment
  • PC sound cards

One of the most common uses of a BoB is to customize audio and video (A/V) signals. Not only is the A/V connector away from the A/V source, but the BoB allows each compound electrical connector to be separated for individualized customization. The BoB improves the quality of A/V signals and is used by many audio/video editors and professional musicians.

Another popular use for a BoB is to test and repair technical equipment because it allows a technician to specially test each component and its connection. Many BoB’s are designed precisely for troubleshooting and repairing electronic equipment.

For home use the BoB can be used for connecting several components.
