intended to alert the user to the presence of uninsulated “dangerous voltage”
within the product’s enclosure that may be of sufficient magnitude to
constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user
to the presence of important operating and maintenance (servicing)
instructions in the literature accompanying the appliance.
WARNING (If applicable): The terminals marked with symbol of “ ” may be of
sufficient magnitude to constitute a risk of electric shock. The external wiring connected
to the terminals requires installation by an instructed person or the use of ready-made
leads or cords.
WARNING:To prevent fire or shock hazard, do not expose this equipment to rain or
moisture.

consoles (paging).
•Configuration memory (presets) management.
•Scheduled events based on calendar.
•Extensive DSP available:
oRouting matrix/mixer, from any input to any output with adjustable level
for crossover points (independent mixes of different inputs for each
output).
oMono or stereo channel processing.
oLevel control, mute, vu-meters and phase adjustment for inputs and
outputs.
oInternal signal generator (sine wave, pink noise, white noise, polarity test).
oParametric EQ on inputs and outputs.

INSTALLATION
5.1. Location, assembly, ventilation
MIMO SG series has been especially designed to be installed in a standard 19" rack, taking
up 1U.
It is very important not to enclose the MIMO SG or expose it to extreme temperatures as
it generates heat. It’s also necessary to promote the passage of fresh air through the
ventilation holes of the chassis, leaving at least one rack unit off between each device and
installed above and below it in the rack frame.
If the setup has several amplifiers in the same rack or in a closed cabinet with doors, it is
highly recommended to supply them forced ventilation, installing fans at the upper and
lower ends. This upward air flow will help to dissipate the heat generated inside.
5.2. Connection to an AC outlet and switching on
All models in the MIMO SG series operate under voltages between 90 and 264 V at 47 to
63 Hz. This device features an over dimensioned power supply that adapts to the mains
voltage in any country of the world with no need to make any adjustments.
On the rear panel, there is a power switch for the unit next to the IEC power connector.
On the front panel, a LED lights up when the unit is switched on.
The mains cables must not be near the shielded cables carrying the audio signal, as this
could cause humming.
5.3. Signal input connections
The rear panel of a MIMO SG unit offers 8 (MIMO88SG) or 12 (MIMO1212SG) balanced
analogue signal inputs, "IN", accepting both line and microphone level signals. Input signal
type selection and management are carried out from EclerNet Manager application.
Please refer to the EclerNet Manager software manual for more information.
Signal input connectors are 3 position screw terminal block. The wiring is:
Hot or direct signal > Terminal +
Cold or inverted signal > Terminal -
Ground > Terminal ⊥
For unbalanced connection short-circuit pin ⊥to pin -.

8
5.4. Audio Output Connections
The rear panel of a MIMO SG offers 8 (MIMO88SG) or 12 (MIMO1212SG) analogue signal
outputs "OUT", all balanced and accepting line level
signals.
Signal output connectors are 3 position screw terminal
block. The wiring is:
Hot or direct signal > Terminal +
Cold or inverted signal > Terminal -
Ground > Terminal ⊥
For UNBALANCED connections, leave the –terminal unconnected.
5.5. ETHERNET port for programming and control
An RJ45 type connector allows connecting the equipment to an Ethernet network:
•Management from EclerNet Manager application. Please refer to the EclerNet
Manager Software manual for more information.
•Possibility of direct connection (point to point) between a computer and a MIMO SG
unit.
•Connection to third party other devices. (Crestron, AMX, Vity, Medialon, etc.
Registered trademarks of their manufacturers). Protocol used: Ecler TP-NET. See
the TP-NET protocol manual for more information.
•Connection to WPmSCREEN units (remote control of an entire network of EclerNet
devices through custom graphic panels).
5.6. REMOTE port for digital remote controls
The REMOTE port allows the connection of digital remote-control
devices, such as the WPTOUCH wall panel or the MPAGE16 paging
console. The REMOTE port is connected to the digital control bus the
remote devices are daisy-chained to, the last one being loaded with a
120 termination resistor between CAN HIGH and CAN LOW.
Refer to the remote device documentation (WPTOUCH, MPAGE16, etc) for more
information about your connection and controls.

Please refer to the EclerNet Manager Software manual for more information about
programming a MIMO SG to manage the remote devices that are connected to the
REMOTE port.
5.7. GPI Remote Control Ports
The rear panel of the MIMO SG offers 8 (MIMO88SG) or 12 (MIMO1212SG) GPI inputs
for 0-10 VDC continuous control voltage. Each of these inputs can be connected to an
external physical device (potentiometer, contact closure, continuously variable voltage 0-
10V DC, etc.) and assigned to a MIMO SG function, as for example:
•Input, output channel or matrix crosspoint volume remote control by means of a
WPmVOL physical knob or an Ecler WPm Series’ WPVOL-IR remote control
•MUTE or SOLO activation/deactivation by means of a switch or contact closure
•Recalling a preset with a push button or contact closure
GPI connectors are screw terminal blocks with three-contacts. The wiring is as follows:
Positive, + 10 VDC > Pin +
Variable voltage, 0-10 VDC > Pin ↑
Ground > Pin ⊥
WPaVOL connection to MIMO serial GPI ports
Jumpers position: ALOG / LIN →LIN position
+12 / +10 →+12 position
WPaVOL RJ45 pin 6 (+12VDC/+10VDC)
WPaVOL RJ45 pin 2 (Remote ZONE.)
WPaVOL RJ45 pin 1, 3 or 7 (GND)

10
WPaVOL-SR connection to MIMO serial GPI ports
Connecting cables can be up to 500 meters with a minimum section of 0.5 mm2.
Consult your ECLER dealer or www.ecler.com about the WP series remote control wall
panels and other accessories available for connection to the GPI port.
5.8. Remote control RS-232 Port
The built-in RS-232 port in the rear panel allows an external device to communicate with
a MIMO SG unit via serial connection. Said connection uses the TP-NET protocol syntax
so to enable the external device to obtain the value of any of the parameters of the MIMO
SG unit (by "GET" commands) and/or modify said values (“SET” commands). See the TP-
NET protocol manual for more information.
The serial connection should comply with the following specifications:
Baud rate: 57600 (fixed, no auto negotiation)
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None

5.9. Front panel controls and LED indicators
The following elements are available on the MIMO SG series front panel:
•Input LED indicators: indicate the presence of audio signal at the unit’s input, and
its intensity level (green, amber and red indicate in this order the increased intensity
level)
•Output LED indicators: indicate the presence of audio signal at the unit’s output,
and its intensity level (green, amber and red indicate in this order the increased
intensity level)
•Status LED indicators (STATUS):
oDATA: Off: there is no connection to EclerNet Manager even if connected
to Ethernet. On: connected to EclerNet Manager or to other third party
application via TP-NET protocol. Flashing: data traffic with EclerNet
Manager or another application.
oPOWER: Illuminates when the unit is in operation. It flashes if there is an
error in the unit or if firmware is not correct. It also flashes when you update
firmware
CLEANING
The front panel should not be cleaned with dissolvent or abrasive substances because
silk-printing could be damaged. To clean it, use a soft cloth slightly wet with water and
neutral liquid soap; dry it with a clean cloth. Be careful that water never gets into the unit
through the holes of the front panel.
