The “Assign ID” procedure for a device makes the internal network controller to perform two opera ons: reset the current ID; search the
fi
rst free
ID in the network, star ng from ID=1. If no other devices are connected (and powered on), the controller assume ID=1, that is the
fi
rst free ID,
otherwise it searches the next one le free.
These opera ons ensure that every device has it’s own unique ID, if you need to add a new device to the network you simply repeat the opera on
of step 4. Every device maintains its ID also when it is turned-o
ff
, because the iden
fi
er is stored in the internal memory and it is cleared only by
another “Assign ID” step, as explained above. This means that if your network is made always of the same devices the assigning ID procedure must
be executed only the
fi
rst me the system is turned on.

Useful tools to set up properly a ver
Ɵ
cal array system
This is a list of tools that can be very useful to set properly a ver cal array system.
CABLE TESTER
It is a good prac ce to check all cables before each installa on, because even one faulty cable can compromise heavily the
system performance.
INCLINOMETER WITH LEVER
This tool can be used to verify the ver cal array angle. It can be used at the top or at the bo om of the array In this
case you have to sum all splay angles, so the maximum precision is needed for aiming the ver cal array, par cularly
for long throw applica ons.
LASER DISTANCE METER
This instrument can be useful to measure the height of the ver cal array and to know the distance between FOH-Subs and FOH-Array
for se ng the delay me.
SMAART or similar acous
Ɵ
c measurement system
These are useful to measure delays, phase and response of the system.
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 USING EXAMPLE
In order to op mize the array performances for this speci
fi
c applica on, the
PRESETS should be used in the following way.
Load the STANDARD preset in the central boxes.
Load the LONG THROW preset in the TOP 1 or 2 boxes, in order to compensate
the loss of power level and high frequencies of the program sent the upper
deck of the theatre.
Load the DOWN FILL / SINGLE BOX preset in the BOTTOM box in order to
smooth the high frequency content of the program sent to the audience close
to the stage.
