POWER PANEL
MAINS IN -
Powercon® NAC3FCA power input connector (blue). To switch the
amplifier on, insert the Powercon® connector and turn it clockwise into the ON
position. To switch the amplifier off, pull back the switch on the connector and
turn it counter-clockwise into the POWER OFF position.
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 specifications indicated on the
amplifier unit. The power supply must be protected by a suitably rated
thermo-magnetic 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.
POWER 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 AX2010A loudspeakers, with 120V~ we suggest to link
a maximum of 2 AX2010A loudspeaker.
CONTROL PANEL
ON -
This LED indicates power on
status.
PROT -
This red LED lights when
the amplifier module is in protect
mode for an internal fault and,
consequently, the amplifier 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.
INPUT -
Audio signal input with
locking XLR connector. It has a
fully electronically balanced
circuitry including AD conversion
for the best S/N ratio and input
headroom.
LINK -
A direct connection from
the input connector to link other
speakers with same audio signal.
GND LIFT -
This switch lift the
ground of the balanced audio
inputs from the earth-ground of
the amplifier module.
PRESET BUTTON -
This button has two function:
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 operation. 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 vertical flown arrays that may range from 4 to 8 boxes or for the centre region of a bigger flown 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
distribution 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 bottom boxes (usually 1 or 2
SINGLE BOX
boxes) of a large flown 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
setting, 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 software and save the PRESET into USER MEMORY no. 1.
Note: see also the example further on this manual.
NETWORK IN/OUT -
These are a standard RJ45 CAT5 connectors (with optional NEUTRIK NE8MC RJ45 cable connector carrier), used for PRONET
network transmission of remote control data over long distance or multiple unit applications.
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.
