Rear Panel

This will explain the functions and names of the components on the rear panel of the DM7 Series.

a

[OMNI OUT]

Balanced XLR 3-pin chassis output connectors for analog audio signals.

b

[INPUT]

Balanced XLR 3-hole chassis input connectors for analog audio signals from line-level devices or microphones.

c

Exhaust vent

This product is equipped with a cooling fan. This vent lets warm air escape from the unit. Make sure that the vent is not blocked with obstructions or other objects. Intake air is provided through vents on the lower front and rear sides.

CAUTION

  • Do not block the ventilation ports (heat dissipating slits) on this product. To prevent increased internal temperature, there are ventilation holes on the front and rear of the product. If the ventilation ports are blocked, heat will be trapped inside the product, which may cause malfunction or fire.

d

AC IN connectors [A]/[B]

Connects to the supplied power cords. Connect the power cords to this unit, then connect the plug ends into the outlet. When connecting the power cords, insert all the way until they lock in place securely. The supplied AC power cords feature a V-lock mechanism with a latch, which prevents the power cords from disconnecting accidentally.

CAUTION

  • Ensure that the power to the unit is turned off before connecting or disconnecting the power cord.

To disconnect a power cord, remove it while pressing the latch on the plug.

e

[ ｜ ]/[ z] (Power switch)

Toggles the power between ON ( ｜ ) and OFF (z). If the unit will not be used for a long time, be sure to remove the power cord from the AC outlet.

When the switch is (z), the power is off.

NOTICE

  • Turning the unit on/off in rapid succession can cause it to malfunction. After turning the unit off, wait at least six seconds before turning it on again.

NOTE

  • This product will operate normally when one or both power supplies [A] and [B] are on. If both power supplies are on and one of the power supplies fails during operation, the unit automatically switches to the other power supply.

f

[AES/EBU]

The DM7 is equipped with a sampling rate converter on 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 outputting digital audio signals in the AES/EBU format.

g

[TC IN]

This balanced XLR 3-hole chassis input connectors accepts time code signals from the connected external device.

h

[WORD CLOCK OUT/IN]

These are BNC connectors used to transmit/receive word clock signals to/from an external device. The [WORD CLOCK IN] connector is internally terminated by a 75-ohm resistor.

i

[GPI]

This is a D-sub 15-hole chassis connector that allows communication (5-in/5-out) with a GPI-compatible external device.

j

[PY]

This card slot allows you to install a PY card (sold separately) to expand the number of I/O ports.

k

Dante [PRIMARY]/[SECONDARY]

These terminals are used to connect to I/O devices such as the Rio3224-D2 to a Dante audio network. Use RJ-45 connectors that are compatible with Neutrik etherCON CAT5e connectors.

  • NOTICE
  • Use an STP (Shielded Twisted Pair) cable to prevent electromagnetic interference. Make sure that the metal components of the connectors are electrically connected to the STP cable’s shield by conductive tape or other similar methods.

    • Do not use the network switch's EEE function(*) within 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 the Dante network when it is not appropriate, resulting in poor synchronization performance and occasional dropouts. Therefore, we strongly recommend that:

    • When using a managed switch, turn off the EEE function on all ports used for Dante. Do not use switches that cannot turn off the EEE function.
    • When using unmanaged switches, do not use switches that support the EEE function. The EEE function cannot be turned off on these switches.

    *The EEE (Energy Efficient Ethernet) function is a technology that reduces switch power consumption during periods of low network traffic. It is also known as Green Ethernet or IEEE802.3az.

l

[LINK/ACT]

[PRIMARY] and [SECONDARY] indicators show the respective communication status. If the Ethernet cables are connected properly, the indicators will flash rapidly.

m

[1G]

These indicators light up when the Dante network is functioning as Gigabit Ethernet.

n

[USB TO HOST]

This is a USB Type-C (USB2.0) port.

By connecting a computer with a USB cable, the console can function as a 96 kHz/32-bit or 48 kHz/32-bit audio interface with a maximum of 18 inputs and 18 outputs. It also allows you to use USB-MIDI to control a DM7 Series unit and remotely control DAW software.

The Yamaha Steinberg USB Driver must be installed to communicate with the computer.

NOTICE

  • Use USB cables less than 3 meters in length.
  • Leave an interval of at least 6 seconds between plugging and unplugging the USB cable.

o

Network connector

This RJ-45 connector allows the unit to be connected to a computer via an Ethernet cable (CAT5 or higher recommended).

NOTICE

  • Use an STP (Shielded Twisted Pair) cable to prevent electromagnetic interference.

p

Grounding screw

Each supplied power cord has 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.
