DM7 Console Owner’s Manual 13
6[AES/EBU]
The DM7 is equipped with a sampling rate converter at
both the [IN] and [OUT] chassis connectors. Please
note that the DM7 COMPACT, which features only the
[OUT] chassis connectors, is not equipped with a
sampling rate converter.
[IN] (DM7 only)
These are balanced XLR 3-hole chassis input connectors
that accept digital audio signals in the AES/EBU format.
[OUT]
These are balanced XLR 3-pin chassis output connectors
for digital audio signals in the AES/EBU format.
7[TC IN]
This balanced XLR 3-hole chassis input connector accepts
time code signals from the connected external device.
8[WORD CLOCK OUT/IN]
These are BNC sockets used to transmit and receive
word clock signals to and from an external device. The
[WORD CLOCK IN] is internally terminated by a 75 ohm
resistor.
9[GPI]
This is a D-sub 15-hole chassis connector that allows
communication (5-in/5-out) with a GPI-equipped
external device.
0[PY]
This card slot enables you to install a separately-sold PY
card to expand the number of I/O ports.
(“Installing Optional Cards” page 16).
ADante [PRIMARY]/[SECONDARY]
These connectors are used to connect to other Dante
audio network devices, such as an Rio3224-D2 I/O
device. Use RJ-45 plugs that are compatible with
Neutrik etherCON CAT5e connectors.
These connectors support up to 144-in/144-out, and
96 kHz/24 or 32-bit, or 48 kHz/24 or 32-bit audio.
NOTE
• Use STP (Shielded Twisted Pair) cable to prevent
electromagnetic interference. Make sure that the metal
parts of the plugs are electrically connected to the STP
cable shield by conductive tape or comparable means.
• Please do not use the EEE function (*) of network
switches in a Dante network.
Although power management should be negotiated
automatically in switches that support EEE, some
switches do not perform the negotiation properly. This
may cause EEE to be enabled in Dante networks when
it is not appropriate, resulting in poor synchronization
performance and occasional dropouts.
Therefore we strongly recommend that:
- If you use managed switches, ensure that they allow
EEE to be disabled. Make sure that EEE is disabled
on all ports used for real-time Dante traffic.
- If you use unmanaged switches, make sure to not
use network switches that support the EEE function,
since EEE operation cannot be disabled in these
switches.
* EEE (Energy Efficient Ethernet) is a technology that
reduces switch power consumption during periods of
low network traffic. It is also known as Green Ethernet
and IEEE802.3az.
B[LINK/ACT]
These indicators show the communication status of the
[PRIMARY] and [SECONDARY] respectively.
If the Ethernet cables are connected properly, the
indicators will flash rapidly.
C[1G]
These indicators light when the Dante network is
functioning as Giga-bit Ethernet.
D[USB TO HOST]
This is a USB Type-C (USB2.0) connector.
By connecting a computer here via a USB cable, the
console can function as an up to 18-in/18-out,
96 kHz/32-bit or 48 kHz/32-bit audio interface. It also
enables you to use USB-MIDI to control any DM7-series
unit and remotely control DAW software.
You must install the Yamaha Steinberg USB Driver to
communicate with the computer. For more information,
refer to the DM7 series Reference Manual.
ENetwork connector
This RJ-45 connector allows the unit to be connected to
a computer via an Ethernet cable (CAT5 or higher
recommended).
You can control the unit from supported application
software, such as DM7 Editor.
NOTE
Use STP (Shielded Twisted Pair) cable to prevent
electromagnetic interference.
FGrounding screw
Each supplied power cord features a three-prong plug.
If the AC outlets are grounded, this product will be
properly grounded through the power cords. Also,
grounding this screw may effectively eliminate noise
such as hum and interference.
NOTICE
• Use USB cables less than three (3) meters long.
• Leave an interval of at least six (6) seconds between
plugging and unplugging the USB cable.
