1. Prepare the S6L Control Surface
Prepare the S6L control surface by removing the back cover and specific modules as explained in the following sections.
Remove the S6L Back Cover
To remove the S6L Back Cover:
1Using a 2.5mm Hex driver, remove the 8 fasteners that secure the back cover to the S6L chassis and set the screws aside.
2After removing the 8 fasteners try sliding the back cover off the chassis by pushing it down with your hands and simultaneously
pulling the cover away from the chassis.
If the cover does not slide freely, try inserting a small flathead screwdriver along its upper edge as shown in Figure 1 and try to
work one side free and then the other.
3Slide the panel away from the control surface, and set the panel aside.

2. Remove the SBC Tray
The SBC Tray must be removed from the chassis before replacing the AVB board assembly or any of the I/O boards.
To remove the SBC Tray:
1Remove the black rubber stopper from the purple plastic shroud, and set it aside (you will re-install it after replacing the SBC).
This stopper must be removed to access one of the captive screws that secures the SBC Tray to the chassis.
2With the stopper removed, use a #2 Phillips screwdriver to loosen the captive screw below the stopper hole.
3Using a #2 Phillips screwdriver, remove the two fasteners securing the top edge of the purple shroud to the top of the chassis.

4Locate the two captive screws securing the SBC Tray to the chassis.
5Using a #2 Phillips screwdriver, loosen the two captive screws shown in Figure 5.
In the next step you will lift the Tray out of the chassis and hang it off the back edge of the console chassis. You should not need
to disconnect any cables before lifting the Tray out, but you may need to guide one or more of them away to allow the Tray to be
lifted out of the chassis. If you find you do need more slack, note and/or label and then disconnect any cable that isn't long enough
to allow the Tray to be lifted out of the chassis.
6Being very careful to not stretch any cables, use two hands to lift the tray out of the chassis. Tilt the Tray as needed to clear the
chassis, and make sure no cables are caught or stretched.

7Align the edge of the Tray with the edge of the chassis and hook the Tray on the edge as shown in Figure 8 so that the Tray hangs
off the chassis.
8Do the following for better access to the I/O board assembly:
• Being careful not to stretch or strain any cables or connectors, slide the SBC Tray to the left and guide its cables to the left so
they do not block access to the I/O board assembly.
• If any SBC cables are too short to let you position the SBC or its cables out of the way, photograph and/or label and then dis-
connect those cables (be sure you will be able to re-connect them to their correct ports after completing the procedure).
9Proceed to 3. Remove Old I/O Boards.

3. Remove Old I/O Boards
The I/O boards in the S6L control surface are stacked and mounted in the I/O cage. To replace any I/O board you must first dis-
connect and remove any boards above it in the cage.
• If you are replacing only the Analog In board (top-most I/O board) you only need to remove and replace that board.
• If you are replacing the Analog Out board you must first disconnect and remove the Analog In board, replace the Analog Out
board and then re-install and re-connect the Analog In board.
• Similarly, if replacing the AES Digital I/O board you must first remove both the Analog In and Analog Out boards.
Follow the instructions in this section to remove as many boards as necessary.
Remove the Analog Input Board
To remove the old Analog Input board:
1Disconnect the ZIF (zero inertion force) ribbon cable connected at the back of the card.
To release this cable, use your finger or fingernail to carefully pull the top-mounted tab up from its locked position (down, to the
left) to its unlocked position (up), then carefully pull the ribbon cable away from the connector.
2Using a #2 Phillips screwdriver, loosen the 4 captive screws shown in Figure 11 that secure the Analog In board to the IO cage.

3Carefully lift the Analog In board out of the chassis. Lift the back first, slide the assembly towards the front of the control surface
so the faceplate clears the back of the chassis, then lift the Analog In board up and out.
4If you are only replacing the Analog In board, proceed to 4. Install New IO Boards.
5If you are replacing the Analog Out or AES Digital I/O board, proceed to the next section (Remove the Analog Out Board).
Remove the Analog Out Board
Removing the Analog Out board is very similar to removing the Analog In board.
To remove the Analog Out board:
1Make sure you have disconnected and removed the Analog In board as explained previously.
2Disconnect the ZIF ribbon cable connected to the back of the Analog Out board.
3Using a #2 Phillips screwdriver, loosen the 4 captive screws that secure the Analog Out board to the cage.
4Carefully lift the Analog Out board out of the chassis. Lift the back first, slide the assembly towards the front of the control sur-
face so the faceplate clears the back of the chassis, then lift the Analog Out board up and out.
5If you are only replacing the Analog Out board, proceed to 4. Install New IO Boards.
6If you are replacing the AES AES Digital I/O board, proceed to the next section (Remove the AES Digital I/O Board).

Remove the AES Digital I/O Board
The AES Digital I/O board has two headphone cables, a power cable, and one primary ZIF ribbon cable that must be disconnected
before removing the board. After removing the old board from the chassis you must transfer the two, shorter “jumper” ZIF ribbon
cables from the old board to the new board, then install the new board into the chassis and make necessary connections.
To remove the AES Digital I/O board:
1Identify and then disconnect cables connected to the old AES Digital I/O board (refer to Figure 13).
• Disconnect the multi-color power cable (labeled Ain Figure 13).
• Disconnect the ZIF ribbon cable labeled Bin Figure 13. To release this cable, use your finger or fingernail to flip the
top-mounted cable tab up to its unlocked position, then carefully pull the cable out of the connector.
• Disconnect the two headphone cables (labeled Cand Din Figure 13). Be sure to note and if necessary label which cable con-
nects to which connector.
• Do not disconnect the two ZIF cables (not labeled in Figure 13). You will transfer these to the new board after removing the
old board from the chassis.
2Using a #2 Phillips screwdriver, loosen the 4 captive screws that secure the AES Digital I/O board to the cage.
3Carefully lift the AES Digital I/O board out of the chassis. Lift the back first, slide the assembly towards the front of the control
surface so the faceplate clears the back of the chassis, then lift the board up and out. Set the old board on your work surface.
4Remove the new AES Digital I/O board from its packaging and set it next to the old board on your work surface.
5Making sure to remember which is the old board and which is the new board, disconnect and transfer the two ZIF ribbon cables
from the old AES Digital I/O board to the same corresponding ZIF connectors on the new board.
• The two ribbon cables are different lengths; be sure to connect each to the correct port on the new board (the longer cable con-
nects to the left connector, and the shorter to the right when standing at the front of the board as shown in Figure 14).
• You might need to “open” the ZIF connectors on the new board (use your finger to flip their tabs up to the open position).
• After making sure each ZIF connector is in its open position, gently insert the corresponding ribbon cable into its connector
and flip its catch down to the locked position.
6Proceed to 4. Install New IO Boards.

Install the New AES Digital I/O Board
To install the new AES Digital I/O board:
1Make sure you have already transferred the two ZIF ribbon cables from the old board to the new board as described previously.
2Place the new board in position in the chassis, making sure to orient it correctly and to insert it fully so that its exterior faceplate
is seated correctly against the back wall of the chassis.
3Tighten the 4 captive screws that secure the AES Digital I/O board assembly to the chassis.
4Reconnect all cables that you removed earlier.
• Connect the multi-color power cable to its connector, making sure it clicks into its locked position (labeled Ain Figure 15).
• Connect the ZIF ribbon cable labeled Bin Figure 15. Gently insert the ribbon cable into the connector, then use your finger
to flip the top-mounted cable tab down into its locked position.
• Connect the two headphone cables (labeled Cand Din Figure 15). Be sure to connect each cable to the correct port.
• The two remaining ZIF ribbon cables (labeled Eand Fin Figure 15) that you previously transferred to the new board will be
connected to the Analog Out and Analog In boards.

1Remove the new Analog Out board from its packaging.
2Angle the new Analog Out board into position in the chassis, making sure to orient it correctly and to insert it fully so that its
exterior faceplateis seated correctly against the backwall of the chassis. Makesure the two ZIF ribbon cables on the AES Digital
I/O board are not caught or folded under the Analog Out board.
3Tighten the 4 captive screws that secure the board to the cage.
4Reconnect the shorter ZIF ribbon cable (right-most of the two, labeled Fin Figure 15) from the AES Digital I/O board to the ZIF
connector on the Analog Out board. Gently insert the ribbon cable into the connector, then use your finger to flip the
top-mounted cable tab down into its locked position.
5Proceed to Install the Analog In Board.
Install the Analog In Board
To install the Analog In board:
1Remove the new Analog In board from its packaging.
2Angle the new Analog In board into position in the chassis, making sure to orient it correctly and to insert it fully so that its ex-
terior faceplate is seated correctly against the back wall of the chassis.
3Tighten the 4 captive screws that secure the board to the cage.
4Reconnect the remaining, longer ZIF ribbon cable (left-most of the two, labeled Ein Figure 15) from the AES Digital I/O board
to the ZIF connector on the Analog In board. Gently insert the ribbon cable into the connector, then use your finger to flip the
top-mounted cable tab down into its locked position.
5Lift the Tray off the edge of the chassis and carefully re-insert it into the chassis.
Angle it in as necessary. You can use one hand to keep cables clear while using the other hand to angle the Tray in.
6Double-check that you have reconnected any SBC cables you might have disconnected to make room for the AVB assembly.
7Make sure the Tray is fully seated in the chassis and that the tabs protruding up from the chassis align with and fit into their slots
in the bottom of the Tray.
8Using a #2 Phillips screwdriver, secure the Tray to the chassis by tightening the 3 captive screws you loosened earlier (including
the one accessible through the hole in the shroud).
