5.2. Phones output

In the MONITOR section, the PHONES output allows to monitor any zone output signal, from 1
to 4, as well as the signal received through the fifth input of the equipment, dedicated to high-priority
signals.
In order to obtain the best performance, headphones impedance must be high (200 to 600Ω).
Connect your headphones to the PHONES (14) output on the front panel by means of a standard stereo
1/4" phone jack (ring = right channel, tip = left channel and sleeve = ground). Select the signal to listen
with the ZONE selector (12) and set its volume with the rotary knob VOL.

6. CONSIDERATIONS AND START-UP

6.1. Power-up

This is done by means of the Power switch (27). Although the MIMO54 produces minimum noise
at power-up, it is highly recommended to power up all devices according to the following sequence:
sound sources, mixers, processors and equalizers and, finally, power amplifiers. The sequence has to
be reversed for power-down. Following this order will prevent transients produced by devices powering-
up/down to affect the following devices in the chain, remaining inaudible.

6.2. Input gain

The gain is controlled with the GAIN volume knob (4) for each input.
The SP indicator (2) lights to indicate a signal presence in this input.
The CLIP indicator (3) warns that the channel is nearly overloaded. As a rule of thumb, this
indicator should never stay permanently lit.
On the front panel, Input # 5 has a GAIN knob acting as a general control of this signal send to
zone outputs in Priority mode (see 4.2. Input 5, priority). Additionally, inside the unit, 4 adjustment
potentiometers allow to attenuate the individual signal sent from Input 5 to the 4 output zones, customising
this input sound volume for the different zones in Priority mode. Please also refer to section 9.
CONFIGURATION DIAGRAM for information about the location and the setting of these potentiometers.

6.3. Destination selection for Input #5 / MPAGE4 microphone signal

Next to the INPUT 5 gain knob on the front panel, use the ZONE 4 ways switch to define the
destination zones for this input in Priority mode (see section 4.2. Input 5, priority). An output zone (from 1
to 4) is selected as Input #5 destination when its switch is activated (downwards).
Additionally, MPAGE4 console can be used to page destination zones selected in real time.
MPAGE4 control panel has a gooseneck microphone and 6 user keys:
•
ZONE 1 to 4: paging zone selection keys. They have a LED that illuminates when the key
is engaged, indicating that this zone is selected. These are mechanical latching switches
(maintaining their state after being activated)
•
ALL : selects all zones (1, 2, 3 and 4) for paging. It is also a latching switch with a LED
that illuminates when the key is engaged
•
PAGE: non-locking key but with LED indicator, enabling paging while it is pressed.
Paging stops when the key is released ("push to talk"). If MPAGE4 unit is configured to
produce a ring chime, it will be played first at the moment you press the PAGE key
When using a MPAGE4 console with the MIMO54, bear in mind the following points:
•
The MIC/LINE input 5 sensitivity dial must be set to the LINE position.
•
The PRIO MODE internal jumper which defines how the PRIO/EVAC function works
should ideally be in the CONTACT position (contact closure activation using the MPAGE4
keys). By default it is the VOICE position (automatic activation by input level detection).
