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.

TURNING ON THE SPEAKER
The amplifiers are equipped with a microprocessor to control the DSP and the amplifier. The correct switch on of the amplifier is ensured by
an initialisation procedure; during this test stage the LEDs (Limiter, Signal and Power Status), located on the amplifier module, remain off
for approx. 2 sec. At the end of the switch on procedure on the amplifier module the Ready green LED only remains steadily on. In case of
severe failure of the speaker, the LED on the front panel flashes several times and on the amplifier module, the Limiter red LED flashes.
The speaker switches to “mute”.
FAILURE INDICATION AND SAFETY
The microprocessor is able to signal three different kinds of failure by flashing the “Limiter” red LED on the amplifier panel before the lighting
up of the “Power status” green LED. The three types of failure are:
WARNING: a non severe error or auto-ripristinate malfunction is detected and the performance of the speaker is not limited.
LIMITATIONS: an error is detected and the performance of the speaker is limited (the sound level is reduced by 3 dB). This does not affect
the operation of the speaker since it continues to operate. However, it is necessary to call the service centre to solve the issue.
FAILURE: a severe malfunction is detected. The speaker switches to “mute”.
FLASHING INDICATION: 1 or 2 Warning 3 or 4 Limitation from 5 to 8 Failure.
In case of failure, the “Ready” green LED remains off.
Perform the checks listed below:
- check if the speaker is properly connected to the power supply
- make sure that the power supply is of correct voltage
- check that the amplifier is not overheated
- disconnect the speaker from the mains power supply, wait for a few minutes and connect it again.
If after these tests the red “LIMITER” LED is still on, please contact an authorised service centre.
