Installing Audio Receptacles
To make analog audio input and output connections, you need to
appropriately connect stripped wires for each audio channel to the
provided audio receptacle. Once done, install the wired receptacle to the
back panel audio input and output connectors. The following procedure
describes this process:
1. Insert a small, flathead screw driver into a rectangular hole of the
audio receptacle. The corresponding round wire hole will open
(either directly above or directly below the screwdriver).
2. Heeding the positive (+), negative (-), and ground (GND) markings
on the back panel, place an appropriate stripped audio wire into the
open hole.
The top row of wire connection holes alternate between positive
and ground. The bottom row of wire connection holes alternate
between negative and ground. See Figure 3-3.

3. Remove the screwdriver to lock the wire into place.
4. Repeat for other wire connections.
5. Once all wiring in completed, plug the receptacle into the analog
audio input ports (each labelled CH1 CH2 CH3 CH4), and then
secure into place with the attached connector screws.
