3. INSTALLATION
3.1. Location, assembly, ventilation
The MIMO88 has been especially designed to be installed in a standard 19" rack, taking up 1U.
It is very important not to enclose the MIMO88 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.
3.2. Connection to an AC outlet and switching on
The MIMO88 operates 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 (20) next to the IEC power connector. On the front
panel, a LED (7) 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.
3.3. Signal input connections
The rear panel of the MIMO88 offers 8 balanced analogue signal inputs, "IN" (9), 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 -.
3.4. Audio Output Connections
The rear panel of the MIMO88 offers 8 analogue signal outputs, "OUT" (8), and two additional "MONITOR"
(10) outputs, 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.
