Connecting the TRS Jacks on the 7U Case 

The main 

Audio I/O 1U 

module ships with a ribbon cable for connecting to a set of ¼” TRS 

audio jacks — either those built-in to the 

Intellijel 7U case

 or those contained within the 

separately available 

Audio I/O Jacks 1U

 module. To connect the 

Audio I/O 1U 

module to an 

Intellijel 7U case

4.

Make note of the small 
triangle icon pointing to a 
pin on each circuit board. 

5.

Plug one end of the ribbon 
cable into the 

Audio I/O 1U

 

module such that the red 
stripe aligns with the pair of 
pins indicated by the 
triangle. 

6.

Plug the other end into the audio jacks circuit board that’s mounted inside the 7U case 
and contains the ¼” jacks, again making sure to align the red strip with the pair of pins 
indicated by the triangle. 

IMPORTANT: Do not connect this jack to a power supply. 

NOTE: Do not try to connect the Audio I/O 1U to the MIDI circuit board, which is 
located at the opposite end of the 7U case.
