Installing the LC4 Expansion Kit(s)
Installing the Kit is straightforward and can be done by anyone with basic technical knowledge and a screwdriver.
Step 1
If the LC4 is installed, turn it off and remove all cables connected to the Expansion Kit. If the RJ45 cables plugged into the Instrument Boxes are not labeled, it is recommended that you label them before removing them from the system in order to make the process of reconnecting them later much easier.
Step 2
Remove the seven black screws from the top panel, seven black screws from the back panel and four screws from the RCA connectors on the back panel as shown in the diagram.

Install the Channel Circuit Board from the Expansion Kit into the Lab Hub by inserting the pin end into the connector on the back panel. Make sure that the holes for the spacers on the Channel Circuit Board line up correctly with the silver spacers.
Step 5
Install the five spacers into the holes in the new Channel Circuit Board to secure it to the Channel Board below it. Add any additional Channel Circuit Boards.

Step 7
Replace the cover and all the screws.
Step 8
Replace all the cables that were unplugged at the beginning of this installation. Make sure that the power is still switched off.
Step 9
Place the new Instrument Boxes with the desired instruments. Plug one end of the instrument cable into the headphone output on the piano and the other end into the Instrument Box INSTRUMENT IN connector. Plug the supplied student headset into the Instrument Box HEADSET and MIC connectors. For best results, set the volume on the instruments to maximum and adjust the trimmer on the side of the Instrument Boxes to a safe, comfortable level for the headsets. Repeat this process until all the instruments are connected to an Instrument Box.
