INSTALLATION
Location, assembly, and ventilation
MIMO7272DN has been specially designed to be placed in a 19″ rack structure,
occupying one unit.
It is very important that, as a heat-generating element, MIMO7272DN is not
completely enclosed or exposed to extreme temperatures. Fresh air should be
allowed to pass through the ventilation holes in the chassis, leaving at least
one free rack unit between each piece of equipment and those installed above
and below it in the rack frame.
If the installation consists of several amplifiers in the same rack or is
carried out inside cabinets closed by means of doors, it is highly
recommendable to equip them with forced upward ventilation, installing fans at
their lower and upper ends. This upward flow of ventilation will favor the
dissipation of the heat generated in its interior.
Mains connection and power on
MIMO7272DN operates on alternating voltages from 90 to 264V and 47 to 63 Hz.
This device is equipped with an oversized power supply capable of adapting
without any type of adjustment to the main voltage of any country in the
world.
On the rear panel, next to the IEC power connector, there is an on/off switch
for the unit.
On the front panel, there is an LED indicator that illuminates when the unit
is in operation.
Do not allow the network cable to run parallel to the shielded cables carrying
the audio signal, as this may cause humming.
Balanced analog audio inputs
MIMO7272DN has on its rear panel 8 analog signal inputs (IN 1 to 8), balanced
and supporting line or microphone levels. The selection of the input signal
type and its management is done from the EclerNet Manager application. Refer
to the EclerNet Manager Application manual for more information. 
The signal input connectors are Euroblock type. The assignment of the connection is as follows:
Live or direct signal > Terminal +
The cold or inverted signal > Terminal –
Ground > Terminal ⊥
For UNbalanced connections, short-circuit the terminal – to earth.
Balanced analog audio outputs
The rear panel of the MIMO7272DN has 8 analog signal outputs (OUT 1 to 8) and
2 additional “MONITOR” monitoring outputs, balanced and with line level.
The signal output connectors are Euroblock type. The assignment of the
connection is as follows:
Live or direct signal > Terminal +
Cold or inverted signal > Terminal –
Ground > Terminal ⊥
For UNbalanced connections, leave the terminal – unconnected.
Digital audio inputs and outputs over IP Dante™
(Ports for primary and secondary networks)
MIMO7272DN allows the reception of 64 channels of digital audio Dante™ and the
sending of 64 channels of digital audio Dante™ through an Ethernet network
compatible with the transport of digital audio over IP through the Dante™
protocol.
The routing of the digital audio signals Dante™ through the Ethernet network,
as well as the network configuration of the ports Dante™ (IP addresses, mask,
etc.) of the MIMO7272DN, is managed by the software application Dante™
Controller. For more information, please refer to the developer’s
documentation: https://www.audinate.com/products/software/dante-controller
MIMO7272DN features two ports with an RJ45 interface in its rear panel that allows the sending and reception of digital audio Dante™, labeled as primary (PRIMARY) and secondary (SECONDARY). MIMO7272DN can work with these ports in two possible modes:
-
Redundant Mode: there are two simultaneous network connections (each with its own IP address, both different) so that the information Ethernet packets Dante™ are transmitted via both connections. Each port (primary and secondary) must be connected to a different physical Ethernet local network, or to a different virtual local network (VLAN), correctly configured and isolated from each other. The digital audio Dante™ is therefore sent and received using two distinct and independent paths, with no possible communication between the primary and secondary ports. In case one of them fails, MIMO7272DN will automatically switch to the other, recovering the audio transmission almost instantaneously. Obviously, to achieve total redundancy, all Dante™ devices that are part of a system of this type must have primary and secondary Dante™ ports, connected respectively to the same two independent networks as MIMO7272DN.
Note: in this mode, if (by mistake) the primary and secondary ports
connect to the same Ethernet network, Dante Controller will no longer have
access to the network configuration control and routing Dante™ of the
MIMO7272DN ports. This control is recovered when one of them is disconnected
from the same network as the other.
Note: Dante™ redundancy requires that the primary and secondary ports of all Dante™ devices connect using the same network connection speed. For example, if the primary port connects to a network with a 1 Gbps link, the secondary port must also connect at 1 Gbps. -
Switched-mode: in this mode, only a single network connection is actually enabled (and therefore only one IP address exists), with the primary and secondary ports behaving as ports of a network switch integrated within MIMO7272DN, to which devices forming part of the system’s Dante™ network, or Ethernet switches forming part of that network’s infrastructure, can be directly connected.
Note: in this mode, both ports primary and secondary, should never be connected simultaneously to network switches, as this would create a loop that would cause network conflicts and disruption of the digital audio Dante™ traffic.
The RJ45 connector labeled ETHERNET allows the connection of the equipment to an Ethernet local network (LAN), is compatible with the following purposes: -
Management from the EclerNet Manager application, by direct connection (CAT5 cable or higher) of a computer with a MIMO7272DN unit or using an Ethernet network as a link between both. Refer to the EclerNet Manager Application manual for more information.
-
Connection to third-party control equipment. (Crestron, AMX, Extron, Medialon, etc. are registered brands from their respective owners). Protocol used: Ecler TP-NET. Refer to the TP-NET protocol manual for more information.
-
UCP: EclerNet project remote control service using customizable graphical control panels. MIMO7272DN can act as a server for these panels, included in an EclerNet project, and also be remotely controlled by UCP panel client devices (WPNETTOUCH, Android®, or iOS® mobile devices, Windows® devices, etc.).
Control remote RS-232 port
The RS-232 port with a DB9 connector built into the rear panel allows an external device to communicate with a MIMO7272DN unit via serial connection. This connection will use the syntax of the TP-NET protocol so that the external device can obtain the value of some of the parameters of the MIMO7272DN unit (by means of “GET” commands) and/or modify these values (“SET” commands). Refer to the TP-NET protocol manual for more information.
The serial connection must comply with the following characteristics:
Baud rate: 115200 (fixed, no auto-negotiation)
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
Remote control GPI ports
The MIMO7272DN rear panel has 8 GPI inputs for direct voltage control, 0 to 12
VDC.
Each of these inputs can be connected to an external physical device (a
potentiometer, a contact closure, a variable 0-12V DC voltage, etc.) and
associated with a MIMO7272DN function, for example:
- Remote control of an input channel volume, output or matrix crossover using a physical potentiometer or a remote control WPa series from Ecler
- Activation/deactivation of a MUTE or SOLO by means of a push-button or contact closure
- Retrieval of a preset by means of a pushbutton or contact closure
The GPI connectors are Euroblock type. The assignment of the connection is as
follows
Positive, + 12 VDC > Terminal +
Variable voltage, 0-12 VDC > Terminal ↑
Ground > Terminal ⊥
Jumpers position: ALOG / LIN → LIN position
+12 / +10 → +12 position
WPaVOL connection to MIMO serial GPI ports
Jumpers position: ALOG / LIN → LIN position
+12 / +10 → +12 position
WPaVOL-SR connection to MIMO serial GPI ports
The connection cables can be up to 500 meters approximately, using a minimum
crosssection of 0,5 mm².
Consult your ECLER distributor or at www.ecler.com about the serial remote- control wall panels WPA series and other accessories available for connection to REMOTE / VCA ports.
Remote control GPO ports
MIMO7272DN has on its rear panel 8 relay outputs NO / NC (normally open / normally closed). Each of these outputs can have its status change associated with a trip by means of a specific function programmed through EclerNet Manager, such as a calendar event or the pressing of a key available on a UCP control panel. In this way, it is possible to interact with external equipment, such as motors for projection screens or movable partition walls, lights, sirens, GPI inputs from other equipment, etc.
OBSERVATIONS
Ground loops
It must be ensured at all times that the signal sources that reach the matrix,
as well as all the devices that are connected to its output, do not have the
grounds interconnected, that is to say, that the grounds never reach them by
two or more different paths, since, in this way, buzzes could be produced that
would even interfere with the quality of the sound reproduction.
The shields of the cables, if they are connected to a chassis, must never be
connected to each other. This way we avoid the formation of ground loops.
Background noise
MIMO7272DN has been designed to obtain the lowest possible background noise.
Regardless of the electronic design, the background noise will depend directly
on the correct use and installation of the unit.
It is not the same, for example, to have the GAIN control of a channel at 2
and the VOL of the output to which it is routed at maximum (case 1), to have a
correct gain setting on the input signal and the VOL level of the output
channels to which it is routed at an intermediate position (case 2). In the
first case, the signal that reaches the mix amplifier, which intrinsically has
its own background noise level, is weak, so the signal-to-noise ratio is low
(low signal). When the output amplifier raises indistinctly the whole set we
will have a very high background noise level at the output.
In the second case, when the input gain is correctly adjusted, the signal
received by the matrix is large and therefore with a large signal/noise ratio
as well, so when this signal reaches the output channels and is amplified, it
will have a better ratio than in the previous case.
