Audio Jacks Board V2 for Intellijel 7U Performance Case

New version of the audio jacks board for 7U cases with additional i/o connectors.

This version is designed to interface to the new Stereo Out 1U, upcoming Stereo In module and to the Pedal I/O  (you can use either pair of jacks as the send/returns) plus Mixups as well.  They are also still compatible with the Audio I/O 1U  1U module. 

Customers can upgrade their older cases with these boards. Very easy to install; just unscrew the 4 jack nuts and swap in the new board!
