yourself and to work in an environment with minimal static to avoid the potential for electrostatic discharge.
Please familiarize yourself with the parts and instructions before proceeding with installation.
Required Tools
You will need the following tools to do the installation:
• #2 Phillips Head Screwdriver
Figure 1.1: #2 Phillips Head Screwdriver

Figure 1.2: Nut Driver for DB25 Side Screws
Figure 1.3: Needlenose Pliers
• (Optional) Power Screwdriver

Each individual upgrade kit has components that are uniquely serialized. Please upgrade one unit at
a time.
Make sure that the serial number on 3d card matches the serial number on your back panel.

Installation
1. Fully power off, disconnect power supply and all other connections to the unit.
2. Remove the six screws from the top of the case:
Figure 1.11: Top Screw Placement
3. Remove the screws from the left and right sides of the case. If the rack ears are fitted, keep their extra
screws separate from the other case screws. Please note that the screws on the rack ears are longer than
the others. Be sure to put the longer screws back in the rack ears when you reassemble the interface.
Figure 1.12: Side Screw Placement, with Rack Ear
If the rack ears are not fitted, there will be three screws per side.
Figure 1.13: Side Screw Placement, No Rack Ear
Remove the top cover.

4. Remove the three screws directly underneath the back panel with a Phillips screwdriver.
Remove the two screws around the 4-pin XLR power connector with a Phillips screwdriver.
Remove the four ring nuts. This can typically be done by hand.
Using pliers or a nut driver tool, loosen and remove the 10 DB25 side screws.
Figure 1.14: Screws and Nuts to Remove from Back Panel
5. Slide off the old back panel and set it aside.
6. If upgrading a LIO-8, remove the two screws holding the Mic In cover plate, then remove the plate
and replace it over the same hole on the new back panel. If upgrading a ULN-8 or LIO-8 with mic
preamps, skip this step.

7. Remove the AES/MIDI board by pulling it up from the top of the 2d board.

8. Mate the pins on the bottom of the AES MIDI board with the pins of the Gasket board. Set this board
cluster aside.

9. Detach the Ribbon cable connecting the master board to the front panel.

10. The Legacy master board and 2d board need to be removed from the unit. They may be removed
individually, or they might come out as a cluster. Rock the 2d board back and forth to loosen it from
the pins on the analog board, pulling upward. The master board may begin to pop off of the metal
posts on the bottom metal. Place a hand underneath the master board to pop it off the remaining posts.
Set the Legacy Master board and 2d card aside.

11. Place down the 3d assembly, lining up the three holes in the 3d base board with the 3 posts in the
bottom metal. Press into place so the base board snaps down on all three posts. If there are rubber
feet present on the bottom metal that were supporting the original master board, peel them off if they
get in the way of the rubber feet under the 3d base board.

12. Place down the bridge board with the extended lip pointing to the BACK of the unit. Very carefully
line up all pins on both the 3d base board and analog board with the bottom holes of the bridge board.
Once lined up, firmly press down.
Figure 1.22: Bridge Board Installed
IMPORTANT: The orientation and alignment of the bridge board is critical. The lip must be
facing toward the back of the unit. The bridge board needs to line up exactly, without any bent
or misaligned pins.

13. Reattach the ribbon cable from the meter board to the matching set of pins on the 3d board that sit
directly behind the ribbon cable coming from the meter board.

14. Install the AES/MIDI board with small section of pins of the attached gasket board lining up to the
matching connection on the 3d board.

15. Attach the new back panel, and replace three case screws on the bottom with a Phillips screwdriver.
Replace two DB25 side screws on either side of the AES DB25 connector with a nut driver tool.
Make sure the MH Link Ethernet stack is flush with its window on the back panel.

16. Attach the power supply, switch the unit on, and confirm that the front panel Power and Internal Clock
Source LEDs turn on.
The LED indications shown on power up indicate that the 3d installation is successful.
Figure 1.27: 3d Front Panel on Power Up
17. Switch the unit off and detach the power supply.
18. On the back panel, replace the remaining eight DB25 screws with the nut driver tool.
Replace two threaded Phillips head screws on either side of the 4-pin XLR power connector.
Replace the four ring nuts. These may be tightened by hand.
