REAR PANEL
- JACK/FEMALE XLR INPUTS (BAL/UNBAL) The system accept jack or XLR input connectors. These balanced inputs can be used to connect balanced or unbalanced microphones or audio sources at line level. The balanced connector is connected in parallel and can be used to send the audio signal to other amplified speakers, recorders or supplementary amplifiers.
- LIMITER LED The amplifier has a built in limiter circuit to prevent clipping of the amplifiers or overdriving the transducers. When the soft clipping circuit is active the LED blinks RED. It is okay if the limit LED blinks occasionally. If the LED blinks frequently or lights continuously, turn down the signal level.
- SIGNAL LED The signal indicator lights green if there is signal present on the main input.
- POWER STATUS LED This green led is ON when the speaker is connected to the mains power source and the ON/OFF switch is in ON position.
- MALE XLR SIGNAL OUTPUT The output XLR connector provides a loop trough for speakers daisy chaining.
- VOLUME CONTROL Adjust the amplifier volume. This control does not affect the “Link” – “Input – Link” output level.
- FLAT/BOOST SWITCH Set the flat or boost equalization “Boost” equalization is a loudness recommended for background music applications, when the system plays at a low level. For all other applications “Flat” equalisation is recommended.
- INPUT SENSITIVITY SWITCH Position the switch in LINE to use a line level source (0 dB) or MIC to use a microphone source.
- IEC AC SOCKET The IEC AC socket connect the power cord to the socket.
- FUSE CARRIER Mains fuse housing.
- POWER MAINS SWITCH The power switch turns the AC power ON and OFF.
WARNING! CAUTION! Loudspeaker connections should be only made by qualified and experienced personnel having the technical know-how or enough specific instructions (to ensure that connections are made correctly) in order to prevent any electrical danger.
To prevent any risk of electric shock, do not connect loudspeakers when the
amplifier is switched on.
Before turning the system on, check all connections and make sure there are no
accidental short circuits.
The entire sound system shall be designed and installed in compliance with the
current local laws and regulations regarding electrical systems.
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.
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”.
VOLTAGE SETUP (RESERVED TO THE RCF SERVICE CENTRE)
200-240 Volt, 50 Hz SETUP:
FUSE VALUE T 3.15 A L 250V
100-120 Volt, 60 Hz SETUP:
FUSE VALUE T6.3 A L 250V
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
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.
