extreme caution. Sudden stops, excessive pushing force and uneven
floors may cause the assembly to overturn. Never tilt the assembly.
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.

4. CONNECTIONS
The connectors must be wired according to the standards specified by the AES (Audio Engineering Society).
BEFORE CONNECTING THE SPEAKER
On the rear panel you will find all the controls, signal and power inputs. At first verify the voltage label applied to the rear panel (115 Volt or 230
Volt). The label indicates the right voltage. If you read a wrong voltage on the label or if you can’t find the label at all, please call your vendor or
authorized RCF SERVICE CENTRE before connecting the speaker. This fast check will avoid any damage.
In case of need of changing the voltage please call your vendor or authorized RCF SERVICE CENTRE. This operation requires the replacement of
the fuse value and is reserved to an RCF SERVICE CENTRE.
BEFORE TURNING ON THE SPEAKER
You can now connect the power supply cable and the signal cable. Before turning on the speaker make sure the volume control is at the minimum
level (even on the mixer output). It is important that the mixer is already ON before turning on the speaker. This will avoid damages to the speaker
and noisy “bumps” due to turning on parts on the audio chain. It is a good practice to always turn on the speakers at last and turning them off
immediately after their use. You can now turn ON the speaker and adjust the volume control to a proper level.
PROTECTIONS
This speaker is equipped with a complete system of protection circuits. The circuit is acting very gently on audio signal, controlling level and
maintaining distortion at acceptable level.
