- The product does not function (or functions in an anomalous way).
- The power cable has been damaged.
- Objects or liquids have got in the unit.
- The product has been subject to a heavy impact.
5. If this product is not used for a long period, disconnect the power cable.
6. If this product begins emitting any strange odours or smoke, switch it off immediately
and disconnect the power cable.
7. Do not connect this product to any equipment or accessories not foreseen.
For suspended installation, only use the dedicated anchoring points and do not try to hang
this product by using elements that are unsuitable or not specific for this purpose. Also
check the suitability of the support surface to which the product is anchored (wall, ceiling,
structure, etc.), and the components used for attachment (screw anchors, screws, brackets
not supplied by RCF etc.), which must guarantee the security of the system / installation
over time, also considering, for example, the mechanical vibrations normally generated by
transducers.
To prevent the risk of falling equipment, do not stack multiple units of this product unless
this possibility is specified in the user manual.
8. RCF S.p.A. strongly recommends this product is only installed by professional
qualified installers (or specialised firms) who can ensure correct installation

4
IMPORTANT
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.
IMPORTANT NOTES
To prevent the occurrence of noise on line signal cables, use screened cables only and avoid
putting them close to:
- Equipment that produces high-intensity electromagnetic fields.
- Power cables.
- Loudspeaker lines.

INNOVATION INTEGRATION INTENSITY
Innovation. Our research and engineering faculty can today offer innovative projects with
finite control of each detail, from the loudspeaker voice coil wire to the highly efficient
extended dynamic amplifier topology. There are many different ingredients that go into
creating quality products and systems. These include computer aided simulation software
to assist the understanding of transducer behaviour and amplifier operation and the
relationship of dynamics and transient response. RCF utilise over thirty state of the art
software packages to identify magnetic circuits, voice coil dynamics, suspension linearity,
horn dispersion simulation, crossover filters, amplifier thermal behaviour etc.
Integration. RCF is one of only a few loudspeaker manufacturers worldwide who have
the ability to completely design and manufactures transducers, speaker systems and

Limiter indicator. The amplifier has a built in compressor/limiter circuit to prevent
clipping of the amplifiers or overdriving the transducers.
When the compressor is active the led is blinking yellow. When the soft clipping circuit is active
the LED blinks orange. It is okay if the limit LED blinks occasionally. If the LED blinks frequently
or lights continuously, turn down the signal level. The amplifier has a built in RMS limiter. If the
RMS limiter is active the LED lights red. The RMS limiter has the purpose to prevent damages
the transducers. The speaker shall never be used with the limit indicator red, continuously.
Continuous operation with the RMS protection active can cause damages to the speaker.

CONNECTIONS
ENGLISH
BAL. XLR
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 delay is expressed in meters. The delay resolution is 0.1 up to 10 meters and 1 from
10 to 20 meters.
To set the system time delay push the delay encoder and rotate it until the wanted setting
is displayed. Push the encoder again to confirm the setting.

RDNet CONNECTION
The system is equipped with an RDNet connection on board.
Using an RDNet controller unit it is possible to:
- receive status information from the system (amplifiers status, signal levels, system
settings,…).
- Send commands to the system (mute, solo, change sensitivity, change setting, set user
eq, …).
- See the RDNet user manual for details.
RDNet BY-PASS SWITCH
When the RDNet is present and the RDNet LINK LED is green the controller takes control
over the module independently of the BY-PASS SWITCH position.
When the RDNet is not present, the BY-PASS switch act as follow:
- BY-PASS SWITCH pressed (LED ON): the system bypass the input board and reads
the RDNet user settings (last configuration saved).
- BY-PASS SWITCH released (LED OFF): the system reads the input board and bypass
the user setting eventually loaded ion the speaker (last configuration eventually saved).
