Input 5, Priority; Phantom Power; Outputs; Zone Outputs - Ecler MIMO54 Notice D'utilisation

Stereo LINE inputs accept 0 dBV (1 V) line level signals from CD and DVD players, multimedia
devices, MP3 players, radio tuners, TV receivers, etc. Turntables CAN NOT BE CONNECTED directly
to the MIMO54, as none of the inputs has a built-in RIAA preamplifier.

4.2. Input 5, priority

The signal received at the input #5 is processed as a high-priority signal, having two kinds of
operation:
•
Priority mode or Talkover:
Attenuates the program signal in all zone outputs, superimposing #5 input signal.
Destination zone selection can be done from the front panel micro-switches (labeled
ZONE), or from zone selection keys on MPAGE4 optional console (see "6.3. Destination
selection for Input #5 / MPAGE4 microphone signal" for more information).
NOTE: you can also use a MPAGE4 console and simultaneously leave some zones
permanently selected as paging destination with front panel ZONE switch. These zones
(permanently selected) always receive voice messages sent from MPAGE4 unit,
regardless of whether they are selected or not by their keys.
Priority mode can be activated by automatic detection of a signal at the 5th input, or by
PRIO potential free contact closure (dry contact) on the back panel.
Internal jumpers are used to select activation mode (signal detection (default) or contact
closure), attenuation (- 20, -30 (default) or - 80 dB) and recovery time (1, 2 (default) or 3
seconds). Please refer to section 9. CONFIGURATION DIAGRAM for more information.
•
Emergency/Evacuation mode:
Mutes the current program signal in All zone outputs and replaces it with Input #5 signal.
Additionally, zone outputs volume controls (front panel knobs and remote panels) are
ignored, as the signal diffusion has a preset volume adjusted with EVAC VOL control on
the back panel.
This mode is only activated by closing the EVAC potential free contact on the back panel.

4.3. Phantom power

An internal jumper activates the Phantom power supply for all microphone inputs at a time,
allowing to connect condenser microphones. Please refer to section 9. CONFIGURATION DIAGRAM for
more information.

5. OUTPUTS

5.1. Zone outputs

The MIMO54 has four main or zone outputs, all balanced and with Euroblock connectors: ZONE
1, ZONE 2, ZONE 3 and ZONE 4.
Euroblock connector should be wired as indicated:
Hot or direct signal
Cold or inverted signal
Ground
On these outputs, a balanced circuit emulates a transformer. To use an output in unbalanced
mode, you must short unused output pin to ground. Otherwise the output signal won't have the suitable
level and quality.
