What could be more rock solid? All of the important bits are held inside, protected by a 14-gauge steel force-field. The inputs are: stereo mini jack, stereo 1/4" jack, and 2 x RCA (with throughput). Internal transformer isolation removes ground loops, making this perfect for laptop, minidisk, i-Pod or unbalanced DJ mixer connection to a professional PA or recording system. 2 x XLR outputs, powered via Phantom only.

  • Easy to use stereo interface for laptop computers
  • Active signal path with transformer isolation
  • Eliminates hum and buzz common to PCs
  • Full connector options set for easy interface

Intended for professional field use, the JPC comes fully loaded with choice of ¼", RCA and 3.5mm input connectors that make it easy to interface with all types of unbalanced audio sources such as computers, iPods, and CD players. It is equipped with isolation transformers to eliminate hum and buzz caused by ground loops and to further reduce system noise; while AC blocking capacitors in the active circuit prevent pollution from the audio system from bleeding back into the computer. Outputs are XLR balanced mic level for easy interface to snake systems and PAs. Powering the JPC is accomplished via 48V phantom from a mixing console. This enables the JPC to be used in concert environments without requiring an external power supply.
