6.3 System Design
Every time that the system is to be installed, it is necessary to simulate it with the LAC software applica-
tion. In chapter 4, we have covered this subject in detail, and it is to be emphasized here that the design
and simulation of the installation is part of the setup procedure and should never be omitted. From the
LAC software it is possible to print a summary and design of the mechanical configuration of the system
for distribution to the personnel responsible for rigging the system.
6.4 Installation of the system
Installation of the system is covered in exhaustive detail in the preceding chapter. Always assure that
the system is installed with maximum attention to and priority on safety.
6.4.1 Power up procedure
Once the system is physically in place and mechanically stable, you can proceed with the connection of
the power amplification. To verify the correct operation of the system, and correct wiring a very simple
procedure can be followed:
1. Power up the amplifiers with output volume completely at the minimum
in MUTE.
2. Apply pink noise generation at the input.
3. Starting from one side, for example Left, take off the Mute from the HIGH output on the processor.
4. Raise the volume on one amplifier at a time to verify that each is coupled to the correct output and
that it is operative. This verification can be effected by ear and with instrumentation. After each
amplifier is verified, its volume should then be returned to zero.
5. Repeat step 4 for each amplifier connected to the HIGH output.
6. Once terminated the verification of the amplification of the HIGH output, return the output to MUTE
on the processor.
7. Repeat steps 3, 4 and 5 for every filtered output of the Left side.
8. Repeat steps 3, 4, 5 and 6 for every filtered output of the Right side.
Once the correct connection and operation of system has been ascertained, you can proceed with
raising the volume on all of the amplifiers.
Upon completion of this procedure, one can be assured that the system is perfectly functional, as
long as the following conditions are also met:
• Each cable has been tested and verified with a tester,
• All power amplifier racks have been correctly wired at the warehouse (or, if new, by the supplier)
• Each electro acoustic system has been measured and tested at the warehouse (or, if new, by the
10
supplier)
)

If the volume/gain control is available, otherwise proceed with a moderate level for pink noise.

The correct procedure starts at HIGH pass band output to the SUB output. In fact, if any wiring is wrong, sending the HIGH
pass band signal to a speaker intended for MID-L does not cause any damage, whereas sending a signal meant for the LOW pass
band to a component intended for HIGH or MID is likely to damage it.

All racks provided by Proel with AXIOM Systems are verified prior to shipping.

All Proel AXIOM Systems are accurately verified and measured at the end of the production line according to state-of-the-art
quality control techniques.
