moved with extreme caution. Sudden stops, excessive pushing force and uneven floors may
cause the assembly to overturn.
10. There are numerous mechanical and electrical factors to be considered when installing
a professional audio system (in addition to those which are strictly acoustic, such as sound
pressure, angles of coverage, frequency response, etc.).
11. Hearing loss
Exposure to high sound levels can cause permanent hearing loss.The acoustic pressure level
that leads to hearing loss is different from person to person and depends on the duration
of exposure. To prevent potentially dangerous exposure to high levels of acoustic pressure,
anyone who is exposed to these levels should use adequate protection devices. When a
transducer capable of producing high sound levels is being used, it is therefore necessary
to wear ear plugs or protective earphones. See the manual technical specifications to know
the maximum sound pressure level.

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 main power supply and the ON/OFF 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.
(HD 32-A features Powercon input/output main connectors)
FUSE CARRIER. Mains fuse housing.
POWER MAIN SWITCH. The power switch turns the AC power ON and OFF.

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”.

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. D-LINE speakers MUST be used only with approved rigging hardware.
WARNING: Never suspend D-LINE speakers by there handles. Handles are intended for
transportation, not for rigging.
