3. INSTALLATION REQUIREMENTS

The MIMO54 has been especially designed to be installed in a standard 19" rack, taking up 1U.
Two considerations must be taken in account when looking for your MIMO54 location: one is the
maximum comfort of use and the other is to allow an easy access to the equipment input and output
connections.
Since the MIMO54 power consumption is very low, it doesn't require forced ventilation.
Nevertheless, you must avoid extreme temperature conditions and keep the atmosphere of the room in
which it is located as dry and dust-free as possible.
Keep the equipment far from noise sources (variable voltage regulators, motors, etc...) as well
as from power cables.
The MIMO54 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.
In order to protect it from potential overloads, the MIMO54 is equipped with a 0.5A time-delay
(slow-blow) mains fuse (28). If it gets blown up, you must replace it with an identical one. NEVER
REPLACE THE FUSE WITH ANOTHER ONE WITH A HIGHER VALUE.
CAUTION: Fuse substitutions have to be performed by a qualified technician.

4. INPUTS

The MIMO54 accepts two types of balanced audio inputs: microphone (MIC) and stereo line
(LINE).

4.1. Inputs 1 to 4, program

Input Channels 1 and 2 accept microphone or line signals. Channels 3 and 4 accept line signals
only. Finally, Channel 5 is dedicated to priority signals and accepts microphone or line signals.
All input terminals are Euroblock connectors, except the XLR type for MIC/LINE L Input 1.
Euroblock connectors wiring diagram is the following:
Hot or direct signal
Cold or inverted signal
Ground
And for XLR connector:
Hot or direct signal
Cold or inverted signal
Ground
Microphones should have a low impedance (200 to 600Ω) and be monophonic. For
UNBALANCED connections, you must short pin 3 (negative) to ground.
For inputs with a MIC/LINE selection, suitable operating position should be set with the dedicated
back panel switch:
•
Engaged: line signal
•
Released: microphone signal
NOTE: In microphone mode the MIC ADJ sensitivity knob located next to the previous switch is enabled.
The gain for each input source (1 to 5) is set with the GAIN rotary knob on the front panel (one
per input channel). Please refer to section 6. CONSIDERATIONS for more information.
