Yamaha DME32 User manual

Hardware Setup Guide

1. Available I/O Options
DME32 has four "MY-Card"(Mini-Yamaha Generic Digital Audio Interface) Slots for I/O. Each card
slot can handle up to 8 channels of I/O for a maximum of 32 I/O per DME32 unit, depending on
the cards chosen.
MY8-AT
Eight ADAT Digital Inputs and Outputs
on Optical Connectors
The current MY-Cards available from Yamaha are a variety of analog and digital formats. It is possible
to mix analog and digital cards in a single DME32 unit. There are no restrictions to any combination
of MY-cards used together in a single unit.
MY8-AD
Eight 20-bit Analog Inputs on 1/4" TRS
Connectors
MY4-DA
Four 20-bit Analog Outputs on XLR
Connectors
MY8-AE
Eight AES/EBU Digital Inputs and
Outputs on a 25-pin D-sub connector

These are the current Remotable External Input/Output devices from Yamaha:
AD824
Eight 24-bit Mic/Line Level Inputs on XLR, with Balanced Inserts on 1/4” TRS connectors, and +48V
Phantom Power. All Functions (Gain Trim and Phantom Power On/Off) can be controlled remotely via
RS-422 (up to 200 meters away). This device accepts one digital MY-Card for its outputs.
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:
4 XLR Inputs, 12 XLR Outputs:
(1) MY4-AD
(3) MY4-DA
8 XLR Inputs, 8 XLR Outputs:
(2) MY4-AD
(2) MY4-DA
12 XLR Inputs, 4 XLR Outputs:
(3) MY4-AD
(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
8 1/4” TRS Inputs, 12 XLR Outputs:
(1) MY8-AD
(3) MY4-DA
16 1/4” TRS Inputs, 8 XLR Outputs:
(2) MY8-AD
(2) MY4-DA
24 1/4” TRS Inputs, 4 XLR Outputs:
(3) MY8-AD
(1) MY4-DA
Slot Component
1 Input 1Ch-8Ch and Output 1Ch-8Ch
2 Input 9Ch-16Ch and Output 9Ch-16Ch
3 Input 17Ch-24Ch and Output 17Ch -24Ch
4 Input 25Ch-32Ch and Output 25Ch-32Ch

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)
An 8-Channel I/O system using ADAT optical transmission. Up to 6 meters of separation is possible.

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.

All that is required is 8 twisted-pairs of shielded 110-ohm wire. Pin to pin ground connections
are optional as long as the shield is connected to the connector hood.

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.
