Thank you for choosing Mackie Designs for your
hard disk recording solution. The OPT•24 is a major
step forward in our continued support of the
HDR24/96 and MDR24/96 Hard Disk Recorders.
The OPT•24 provides 24 channels (8x3) of 24-bit
ADAT optical I/O. But what makes it especially
unique and valuable is that it doesn’t use any of the
three I/O slots provided for the analog and digital
I/O cards. Instead, it is installed in a PCI slot next to
the Sync card. Once installed, you have the added
flexibility of choosing between at least two different
input and output formats for your recorded audio.
For example, you can use three analog AIO•8 cards
to bring the audio into the HDR, and use the
OPT•24 to output the audio in 24-bit digital format.
Installing the OPT•24
.
Important: The OPT•24
contains static-sensitive
components. Anti-static
precautions must be taken before
opening the anti-static bag and
handling the OPT•24. Use an
anti-static wrist strap when performing this installation.
These are available at most computer supply stores.
The use of an anti-static mat is also recommended.
1) Turn off the Hard Disk Recorder and remove
the AC linecord from the socket on the rear
panel. We don’t want this to be a shocking
experience for you!
2) Remove 22 screws from the HDR24/96 cover
using a #2 Phillips screwdriver (4 screws
from the top panel, 4 screws from each side,
and 10 screws from the rear panel). These
screws are all one size.
5) Unplug the 2 ribbon cables from the Sync card. Squeeze the tabs on the sides of the connectors and
gently wiggle from side to side to release them from their sockets.
6) Unplug both ends of the COM cable (040-383-00), located between the front panel Display board (A)
and the Card Cage board (B). Cable ties hold the COM cable in place. Leave the cable inside the
HDR24/96 in case the OPT•24 is ever removed and the COM cable needs to be reconnected.

7) Connect the 2 short/fat ribbon cables (supplied) to the 2 bottom connectors (J3B and J4B, furthest
from the edge) on the OPT•24. The connectors have a keying tab in the center so they can’t be
plugged in wrong. It doesn’t matter which end of the ribbon cables you connect to the OPT•24.

8) Connect the 2 ribbon cables that you removed from the Sync card to the 2 top connectors (J3A and
J4A, closest to the edge) on the OPT•24. They will click in place when properly inserted.
9) Install the OPT•24 into the ACC1 PCI slot by carefully aligning the card’s gold-plated connector
edge to the PCI slot on the motherboard and pushing down gently but firmly until the card is fully
seated into the slot. It may help to gently rock the board front to back until the board is completely
seated.
Note: Make sure the loose connector ends are pointing up so they can be accessed for step 11.
10) Install the screw that you removed from the blank cover plate to secure the OPT•24 to the HDR chassis.
11) Connect the short ribbon cables from the OPT•24 card to the adjacent Sync card by folding them over the
top of the Sync card (see illustration below and on next page).
