I/O AND CONTROL OPERATIONS
MAINS IN -
Powercon® NAC3FCA power input connector (blue). To switch the ampli
fi
er on, insert the Powercon®
connector and turn it clockwise into the ON posi on. To switch the ampli
fi
er o
ff
, pull back the switch on the connector
and turn it counter-clockwise into the POWER OFF posi on.
WARNING!
In the case of product failure or fuse replacement, disconnect the unit completely from the mains
power. The power cable must only be connected to a socket corresponding to the speci
fi
ca
Ɵ
ons indicated on
the ampli
fi
er unit. The power supply must be protected by a suitably rated thermo-magne
Ɵ
c breaker.
Preferably
use a suitable switch to power on the whole audio system leaving the Powercon® always connected to each
speaker, this simple trick extend the life of the Powercon® connectors.
MAINS OUT -
Powercon® NAC3FCB power output connector (grey). This is connected
in parallel with the MAINS ~ / IN. The maximum load applicable depends on the mains
voltage. With 230V~ we suggest to link a maximum of 4 AX2065A loudspeakers, with
120V~ we suggest to link a maximum of 2 AX2065A loudspeaker.
INPUT - Audio signal input with locking XLR connector. It has a fully electronically balanced
circuitry including AD conversion for the best S/N ra o and input headroom.
LINK - A direct connec on from the input connector to link other speakers with same
audio signal.
ON -
This LED indicates power on status.
PROT -
This red LED lights when the ampli
fi
er module is in protect mode for an internal
fault and, consequently, the ampli
fi
er is muted.
SIGN/LIMIT -
This LED lights in green to indicate
the presence of the signal and lights in red when an
internal limiter reduces the input level.
GND LIFT -
This switch li the ground of the balanced
audio inputs from the earth-ground of the ampli
fi
er
module.
PRESET BUTTON -
This bu on has two func on:
1)
Pressing it while powering on the unit:
ID ASSIGN
the internal DSP assigns a new ID to the unit for the PRONET
remote control opera on. Each loudspeaker must have a unique
ID to be visible in the PRONET network. When you assign a new
ID, all the other loudspeakers with the ID already assigned must
be ON and connected to the network.
2)
Pressing it with the unit ON you can select the DSP PRESET. The selected PRESET
is indicated by the corresponding LED:
STANDARD
This PRESET is suitable for ver cal
fl
own arrays that may range
from 4 to 8 boxes or for the centre region of a bigger
fl
own array.
It can be used also for stacked arrays.
LONG THROW
This PRESET can be used in arrays bigger than 6 or 8 boxes and
loaded in the top 1 or 2 boxes in order to obtain a more even
distribu on of the sound pressure, especially if they point very far away or to the upper deck of a large theatre.
DOWN FILL /
This PRESET, which features a much smoother high frequency response, can be loaded in the bo om boxes (usually 1 or 2
SINGLE BOX
boxes) of a large
fl
own array, in order to reach conveniently the audience close to the stage. This preset could be very useful
also when the box is used just on its own as a Front Fill element in the front of very large stages.
USER
This LED lights when the USER PRESET is loaded. This preset corresponds to USER MEMORY no. 1 of the
DSP and, as a factory se ng, it’s the same to STANDARD. If you want to modify it, you have to connect
the unit to a PC, edit the parameters with PRONET so ware and save the PRESET into USER MEMORY no.
1.
Note: see also the PRONET example further on this manual.
NETWORK IN/OUT -
These are a standard RJ45 CAT5 connectors (with op onal NEUTRIK NE8MC RJ45 cable connector carrier),
used for PRONET network transmission of remote control data over long distance or mul ple unit applica ons.
TERMINATE -
In a PRONET network the last loudspeaker device must be terminated (with an inner load resistance) especially
in a long run cabling: press this switch if you want to terminate the unit.
POWER OUT -
AX2065A is able to power an addi onal passive AX2065P module through the available power output on the
back panel.
WARNING: connect a single AX2065P module only.
