The entire audio system must comply with the current standards and regulations regarding electrical systems.
9. Supports and trolleys.
The equipment should be only used on trolleys or supports, where necessary, that are recommended by the
manufacturer. The equipment / support / trolley assembly must be moved with extreme caution. Sudden stops,
excessive pushing force and uneven floors may cause the assembly to overturn.
10. There are numerous mechanical and electrical factors to be considered when installing a professional audio system
(in addition to those which are strictly acoustic, such as sound pressure, angles of coverage, frequency response,
etc.).
11. Hearing loss.
Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure level that leads to hearing
loss is different from person to person and depends on the duration of exposure. To prevent potentially dangerous
exposure to high levels of acoustic pressure, anyone who is exposed to these levels should use adequate protection
devices. When a transducer capable of producing high sound levels is being used, it is therefore necessary to wear
ear plugs or protective earphones. See the manual technical specifications to know the maximum sound pressure
level.
To prevent the occurrence of noise on line signal cables, use screened cables only and avoid putting them close to:
- Equipment that produces high-intensity electromagnetic fields.
- Power cables
- Loudspeaker lines.
OPERATING PRECAUTIONS
- Place this product far from any heat sources and always ensure an adequate air circulation around it.
- Do not overload this product for a long time.
- Never force the control elements (keys, knobs, etc.).
- Do not use solvents, alcohol, benzene or other volatile substances for cleaning the external parts of this product.
GENERAL OPERATING PRECAUTIONS
• Do not obstruct the ventilation grilles of the unit. Situate this product far from any heat sources and always ensure
adequate air circulation around the ventilation grilles.
• Do not overload this product for extended periods of time.
• Never force the control elements (keys, knobs, etc. ).
• Do not use solvents, alcohol, benzene or other volatile substances for cleaning the external parts of this product.
CAUTION
To prevent electric shock hazard, do not connect to mains power supply while grille is removed
FCC NOTES
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio frequency energy, and if it is not installed and used in
accordance with the instruction manual, it may cause harmful interference to radio communications. Operation of this equipment in
a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference at his own
expense.
Modifications: Any modifications made to this device that are not approved by RCF may void the authority granted to the user by
the FCC to operate this equipment.

- As descripted for the low frequencies the user may need to scala up or down the presets set maintaining the compensation ratio between all the cabinets this scaling operation can be performed with the arrow button in the group tab even though the presets change is possible on every single loudspeaker a global change by using the group properties tab is strongly recommended in order to preserve the air absorption compensation distribution all along the audience 17
- High frequency preset using rdnet from the rcf easy shape designer it is possible to export the suggested filters set to rdnet after the selection of all the cabinets in the cluster by pressing the load presets button in the group property tab the user can choose the txt file generated by rcf easy shape designer for the proper load of the filters the group should be composed placing as first loudspeaker of the rdnet cluster the first one below the flybar and then all the others every cabinet should load a proper hf preset and the entire cluster should load the same lf preset once the presets are loaded the icon of every module in the cluster shows a green bar with width directly proportional to the number of the preset loaded in the cabinet the number is shown besides the drawing 17
- High frequency preset using rear panel rotary knob from rdnet the user can have access to all the fifteen presets but using the loudspeaker rear panel rotary knob he can use only four of those filters in addition these local filters are suggested by rcf easy shape designer software 17
