CONNECTIONS
The XLR connectors use the following AES standard:
PIN 1 = GROUND (SHIELD)
PIN 2 = HOT (+)
PIN 3 = COLD (-)
BEFORE CONNECTING THE SPEAKER
On the back panel you will find all the controls, the signal and current inputs. At first verify that the voltage selector
on the speaker is in proper position for your country (115 Volt or 230 Volt).
The switch shall be in proper position (unless moved from unauthorized people), but a fast check will avoid
problems. In case is necessary to change the voltage please call your vendor or authorized RCF SERVICE
CENTRE. This operation require the substitution of the fuse value and is reserved to an RCF SERVICE
CENTRE.
BEFORE TURNING ON THE SPEAKER
At this point you can connect the power supply cable and the signal cable, but before turning on the speaker make
sure that 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 damage to the speakers and noisy “bumps” due to
turning on parts on the audio chain. It is a good practice to always turn on speakers at last and turn them off
immediately after the show.
Now you can turn ON the speaker and adjust the volume control to a proper level.
INSTALLATION
A 35 MM socket for mounting the loudspeaker on a speaker stand is provided in the bottom of the cabinet.
ART speakers MUST be suspended only with approved rigging hardware. In any case always use at least 2 M10
threaded inserts on opposite sides of the cabinet.
WARNING: Never suspend ART speakers by there handles. Handles are intended for transportation, not for
rigging.
PROTECTIONS
ART Series active speakers are equipped with a complete system of protection circuits. Two led on the amplifier
back panel indicate the working status of the amplifier: the green led indicate that the speaker is ON and the red
led is on when the protection circuit is active. The circuit is acting very gently on audio signal, controlling level and
maintaining distortion at acceptable level. If this led is ON for a long period is better to reduce immediately the
signal level from the mixer or from the speaker volume control.
