2. Analog Line Level Only
Here are some examples of utilizing all four card slots for maximum analog line-level card I/O, and
the cards required:
8 1/4” TRS Inputs, 12 XLR Outputs:
(1) MY8-AD
4 XLR Inputs, 12 XLR Outputs:
(1) MY4-AD
(3) MY4-DA
(3) MY4-DA
16 1/4” TRS Inputs, 8 XLR Outputs:
(2) MY8-AD
8 XLR Inputs, 8 XLR Outputs:
(2) MY4-AD
(2) MY4-DA
(2) MY4-DA
24 1/4” TRS Inputs, 4 XLR Outputs:
(3) MY8-AD
12 XLR Inputs, 4 XLR Outputs:
(3) MY4-AD
(1) MY4-DA
(1) MY4-DA
Of course, there are more combinations than the examples above. For example, a 20-input and 4-output
system can be made by using (1) MY4-AD, (2)MY8-AD, and (1) MY-4-DA cards. This gives 4 XLR
inputs, 16 1/4” inputs, and 4 XLR outputs.
And not all card slots need to be filled. If a system only requires 4 inputs and 8 outputs, then a logical
choice for cards would be (1) MY4-AD and (2) MY4-DA.
There is no particular order you have to follow for putting the cards in the slots. Each card slot
corresponds to a specific input and output component block in the software. So if you have only two
cards, it doesn’t matter if you place them in slots 1 and 4, or 2 and 3. You just have to correctly
address them by their card slot numbers in the software.

This setup has 8 inputs and 8 outputs using (2) MY4-AD and (2) MY4-DA

3. Digital I/O
Each of the digital MY-Cards are capable of 8 channels of input and output (MY8-AE, MY8-AT, MY8-
TD). Different format cards can be used together in a single DME32 unit. You can also mix analog and
digital cards together in a single DME32 unit.
For 8 Channels of Digital I/O:
Use one digital MY8 card.
For 16 Channels of Digital I/O:
Use two digital MY8 Cards
For 24 Channels of Digital I/O:
Use three digital MY8 Cards
For 32 Channels of Digital I/O:
Use four digital MY8 Cards
This setup has 16 digital inputs and 16 digital outputs using (1) MY8-AE and (1) MY8-AT
(8 AES/EBU I/O and 8 ADAT I/O)
This setup has 20 inputs and 20 outputs using (2) MY4-AE , (1) MY4-AD, and (1) MY4-DA
(4 analog I/O and 16 AES/EBU I/O)

4. Using the AD824 and DA824
The AD824 and the DA824 have MY-Card slots as well. Using digital MY-Cards, an audio connection
between the DME32 and the AD824 and/or DA824 can be established. Using AES/EBU (MY8-AE
Cards), distances of 200 meters can be achieved. Using ADAT optical transmission (MY8-AT cards),
you can separate the units by 6 meters.
8 Channels of Analog I/O
(1) AD824
(1) DA824
(3) MY8-AE or MY8-AT (One card goes into each DME32, AD824, and DA824)
16 Channels of Analog I/O
(2) AD824
(2) DA824
(6) MY8-AE or MY8-AT (Two cards go into DME32 and one card into each AD824 and DA824)
24 Channels of Analog I/O
(3) AD824
(3) DA824
(9) MY8-AE or MY8-AT (Three cards go into DME32, and one card into each AD824 and DA824)
32 Channels of Analog I/O
(4) AD824
(4) DA824
(12) MY8-AE or MY8-AT (Four cards go into DME32, and one card into each AD824 and DA824)

and the I/O components is possible.
In the example above, a split AES/EBU cable is utilized to connect the DME32 to the AD824
and DA824. See the next section for details on creating this cable.
Since no Wordclock signal is sent to the AD824 units in either the AES/EBU or ADAT
connection examples, Wordclock BNC Cables must be run from the DME32 to the AD824.
Please see Chapter 13 (page 227) of the DME32 Owner's Manual for more information on
Wordclocks.
WORDCLOCK SOURCE SETTING CAUTION
When the wordclock source is changed on the wordclock master device (e.g. AD824 or DME32),
noise may occur from the DA824's analog outputs, especially if an MY8-AT I/O card is installed, so
turn down your power amps, or turn off the DA824 beforehand, otherwise any connected speakers
may be damaged.

5. Creating Split AES Cables
The MY8-AE Card is capable of 8 AES/EBU inputs and outputs via a 25-pin Female D-sub
connector. In order to use this card with a DME32 and AD824/DA824 configuration, a split
AES/EBU cable must be created. You must use shielded 110-ohm twisted-pair AES cable and
25-pin Male D-sub connector on each end.

6. AD824 Connection for Remote Control
The AD824 can be controlled remotely from the DME32 via RS-422. Gain Control and
Phantom Power On/Off can be manipulated and recalled by the DME32. In order to do this,
RS-422 Cables need to be run from the DME32 to the first AD824, and then daisy-chained
to subsequent AD824 units.

AD824 #2
AD824 #3
AD824 #4

AD824 ID numbers are automatically set by their position in the chain. The first AD824
connected to DME32 is unit #1, and the second AD824 is unit #2, and so on. The IDs have
no relation to the slot number they are plugged into. The ID numbers should be noted and will
be used by the software to address them.
