EXAMPLE OF INSTALLATION IN A THEATRE WITH BALCONY
Here below you can see an example of the
use of di
ff
erent PRESETS in an AX2065
fl
own
array installed in a big theatre with balcony.
The TOP BOXES of the array are aiming at the
balcony while the DOWN FILL box is aiming at
the audience close to the stage.
TOP BOXES: the power level at the end of
the balcony is lower, as well as the high
frequency level.
DOWN FILL BOXES: the power level in the
proximity of the stage is higher, as well as the
high frequency level.
PRESET OPERATIONS
In order to op mize the array performances for this speci
fi
c applica on, the
PRESETS should be loaded in di
ff
erent PC260 loudspeaker processors used in
the following way.
Load the STANDARD preset in the
fi
rst PC260 processor that drives the ampli
fi
ers
for the central boxes.
Load the LONG THROW preset in the second PC260 processor that drives the
ampli
fi
es for the TOP 1 or 2 boxes, in order to compensate the loss of power level
and high frequencies of the program sent to the upper deck of the theatre.
Load the DOWN FILL / SINGLE BOX preset in the third PC260 processor that
drives the ampli
fi
ers for the BOTTOM box in order to smooth the high frequency
content of the program sent to the audience close to the stage.
NOTE:
the audio signal send to all PC260 processors must be the same so their
inputs must be linked with a XLR cable.
NOTE:
The outputs 1 and 2 of each PC260 are assigned always to drive the
ampli
fi
ers for the SW215 subwoofers, so you can use indiscriminately the output
1 and 2 of one of them.
IMPORTANT INSTRUCTIONS TO USE GROUPS
If you use more than one PC260 processor to drive the
same ver cal array system as in the example above, you
must always set the same parameters of the input panel for
both processors: levels and delay and any other parameter
must be always the same. The right way to this is the
following:
1) Be sure that each PC260 has not assigned to any device
group.
2) Load the STANDARD, SINGLE/DOWN-FILL, LONG THROW
preset on each dedicated PC260.
3) Assign every PC260 to the same device group.
Now any modi
fi
ca on made on one PC260 is repeated also
on all the others assigned to the same group.
WARNING:
A er you have assigned all the PC260 to the same group, do not load or save preset, because what you do on one unit will be
repeated also on the others (for load and save opera ons you must remove the units from the groups).
EDIT PARAMETERS
In the PC260 presets some parameters can be customized and some other are protected, this
ensure a safe opera on of the system. Here is a brief descrip on of customizable parameters:
IN:
In this screen you can adjust the input levels, compressors/limiters and delay.
The input range can be op mized in the -30 ÷ +6 dB range. The level is set a er the AD
conversion, so if you have problems with an excessive input signal use the analog PAD bu on
on the PC260 back panel.
The compressors are set in order to a enuate very high input signals (the threshold is +12
dB), ensuring a more transparent musical behaviour of the system limi ng. If needed, the
compressor threshold can be freely adjusted.
