ENGLISH
On the back panel you will find all the controls, the signal and current inputs. 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.
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.
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”.

VOLTAGE SETUP
(RESERVED TO THE RCF SERVICE CENTRE)
230 Volt, 50 Hz SETUP: FUSE VALUE T 1.6 A 250 V
115 Volt, 60 Hz SETUP: FUSE VALUE T 3.15 A 250 V
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.
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.
