To connect the HDL300 system with Q-SYS Core 110F CODEC, two custom cables are needed to accommodate the standard 3.5mm jack connector on the HDL300 system's connect module with the standard Euroblock connectors on the Cisco I/O panel.
Creating custom cables
Cable 1: Prepare a 3.5mm jack cable with the standard TRS (tip-ring-sleeve) jack pinout, with the left channel on the tip, the right channel on the ring and the ground on the sleeve. When mono audio is played over this channel, the same audio will be reproduced on both the left and the right channels. TRS pins correspond to positive (+), negative (–) and ground () for an unbalanced signal, wired to the appropriate Euroblock 3-conductor terminal block per the Q-SYS User Manual microphone inputs.
Cable 2: Prepare a second 3.5mm jack pigtail to Euroblock cable, equivalent to cable 1.

From the Q-SYS Core 110f Designer software,
NOTE: The Nureva Aux In / Out connections are single-ended, unbalanced signals with default maximum output signals as given in the table below. Any equipment requiring voltages below these levels may result in clipping, distortion and, in extreme cases, damage to connected systems. Equipment requiring voltages above these levels will not be adequately driven by the HDL300 system’s output signal and may result in quiet / no audio on the channel.
Before connecting to the Connect Module ports, make sure the CODEC provided-voltage levels are adequate or adjusted properly by additional interfacing hardware.
