Optional Extras


  • Patching is not included as users typically want to specify their own patch system or already have a patch system to integrate a console into. Patching is however available and the recommendation for a pre-wired patch system is:
  • 5 x 96-jack bantam patch strips including 11 metre console-to-patch cables – see below »
  • User connections on the rear of the patch strips are 90-way EDAC connectors.

Phantom Power

Phantom power is not supplied to the console mic / line modules and has to be externally injected into the microphone connections. A custom phantom power injector (2U rack case with switches and tally LEDs) is available at an additional cost – see below »
