The new, 2nd generation Audio Jacks Board comes pre-installed in every Intellijel 7U case manufactured since early 2019. Because this board is more fully featured than the previous generation, it’s available as a stand-alone component for anyone who wishes to update an older 7U case.
You can tell which board you have by looking at the connectors. The new Audio Jacks Board has a large shrouded header flanked by two smaller shrouded headers, flanked by two link connectors at either end. Older boards have only one connector along the bottom edge.
The board holds four Neutrik TRS jacks, each of which can be configured as either an input or an output depending on the modules you connect. This allows you maximum flexibility when configuring your case — whether you wish to use the audio jacks as outputs, inputs, sends & returns; or some combination of these.
The jacks carry different audio signals depending on what you connect to the Audio Jacks Board. Please refer to the manual for more details on the many options available.
