DA824  
Eight 24-bit Line Level Outputs on XLR and 1/4" TRS. Selectable maximum output levels of +4,  
+15, +18, and +24db by internal DIP switches independently per channel. This device accepts one  
digital MY-Card for its inputs.  
Using AES/EBU Transmission (via MY8-AE cards), distances of up to 200 meters can be achieved  
between these units and the DME32.  
Using ADAT Optical Transmission (via MY8-AT cards), distances of up to 6 meters can be achieved.

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

A 16-Channel I/O sytem using AES/EBU transmission. Up to 200 meters of separation between the DME32  
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 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.
