PIN 1 = GROUND (SHIELD)
PIN 2 = HOT (+)
PIN 3 = COLD (-)
HOT GND
BAL. XLR
COLD
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.
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 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. The speaker MUST be suspended only with approved rigging hardware.
WARNING: Never suspend the speaker by its handles. Handles are intended for
transportation, not for rigging.
