IMPORTANT NOTES
Before connecting and using the amplifier, please read this instruction manual carefully and keep it on hand for future reference. The
manual is to be considered an integral part of the product and must accompany the amplifier when it changes ownership as a
reference for correct installation and use as well as for the safety precautions. RCF Spa. will not assume any responsibility for the
incorrect installation and/or use of the product.IANO
WARNING: To prevent the risk of fire or electric shock, never expose this equipment to rain or humidity.
SAFETY PRECAUTIONS
1. All the precautions, in particular the safety ones, must be read with special attention, as they provide important information.
2. The power supply voltage of this equipment is sufficiently high to involve a risk of electrocution; therefore, never install or connect
the product with the power supply switched on.
3. Before powering up the amplifier, make sure that all the connections have been made correctly and that the voltage of your power
mains corresponds to the voltage shown on the rating plate on the unit; if it does not, please contact your RCF dealer.
4. The metallic parts of the unit are earthed by means of the power cable. In the event that the current outlet used for power does not
provide the earth connection, contact a qualified electrician to earth the equipment using the dedicated terminal.
5. To protect the power cable from damage, make sure that it is positioned so that it cannot be stepped on or crushed by objects.
6. To prevent the risk of electric shock, never open the amplifier. There are no parts on the inside that the user needs to access.
7. Make sure that no objects or liquids can get into the amplifier, as this may cause a short circuit.
8. Never attempt to carry out any operations, modifications, or repairs that are not expressly described in this manual.
Contact your authorized service centre or qualified personnel should any of the following occur:
-the amplifier does not function (or functions in an anomalous way);
-the power supply cable has been damaged;
-objects or liquids have got into the unit;
-the amplifier has been subject to heavy impact.
9. When the amplifier is not to be used for long periods of time, switch it off and disconnect the power cable.
10. If the amplifier begins to emit any strange odours or smoke, switch it off immediately and disconnect the power supply cable.
11. Do not connect this product to any equipment or accessories not specified.
For suspended installation, only use the dedicated anchoring points and do not try to hang this product using HANDLES or 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 the transducer.
To prevent the risk of falling equipment, do not stack multiple units of this product unless this possibility is specified in the instruction
manual.
12. RCF Spa. strongly recommends this product is installed by professional qualified installers (or specialised firms) who can ensure
correct installation and certify it according to the regulations in force.
The entire audio system must comply with the current standards and regulations regarding electrical systems.
13. Supports and trolleys
The equipment should only be used on trolleys or supports, where necessary, that are recommended by the manufacturer. The
equipment/support/trolley assembly must be moved with extreme caution. Sudden stops, excessive pushing force and uneven floors
may cause the assembly to overturn.
14. 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.).
15. 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 technical specifications in the instruction manual for the maximum sound pressure the loudspeaker is capable of producing
IMPORTANT NOTES
To prevent the occurrence of noise on the cables that carry microphone signals or line signals (for example, 0 dB), only use screened
cables and avoid running them in the vicinity of:
-equipment that produces high-intensity electromagnetic fields (for example, high power transformers);
-mains cables;
-lines that supply loudspeakers.

OPERATING PRECAUTIONS
-Do not obstruct the ventilation grilles of the unit. Situate this product far from any heat sources and always ensure
adequate air circulation around the ventilation grilles.
-Do not overload this product for extended periods of time.
-Never force the control elements (keys, knobs, etc. ).
-Do not use solvents, alcohol, benzene or other volatile substances for cleaning the external parts of this
product.

TT+ HIGH DEFINITION TOURING AND THEATRE
RCF TT+ represents another prominent chapter in the long history of RCF Sound Systems.
Whether a speaker system is designed for live sound or large concert situations as well as permanent installed theatre sound
applications, the paying customer now expects a level of audio fidelity and intelligibility of such a standard unsurpassed by previous
generations.
This requirement has fostered the need for Audio Professionals to be able to offer a range of speaker systems combined with
dedicated Processing and Amplification Technologies that are superior in Acoustic Performance and Control Technology.
RCF TT+ offers ready to use solutions and tools in true active high definition speaker systems.
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 amplification and control electronics. Our 50 plus years heritage in Audio combined
with our state of
the art research and development and manufacturing processes allows us to seamlessly integrate all the ingredients to design and
build TT+
INTENSITY. The design philosophy for the new TT+ series is based upon offering the sound engineer solutions and tools that are
ready to use. Key factors are the ability to sustain very high power with highly efficient sound pressure levels. Intense sound levels are
created with extremely high definition and extended dynamic range. Modern construction materials result in mechanical weight ratios
that are light for practical flying and portability.

SIDE PANEL FEATURES AND CONTROLS
1MAIN XLR INPUT (BAL/UNBAL). The system accept female XLR input connectors and line-level signals from a mixing console
or other signal source.

2SIDE COUPLING. The system provides linear equalisation in case of a single speaker in floor monitoring position. In case of
coupled application (2 speakers side by side) this switch equalise the curve response reducing the low-mid and low frequency
range.
This switch can be used even for a single speaker when a very high intelligibility is required from the monitor.
3INPUT SENSITIVITY. Controls the overall signal level at the input to the power amplifier. The control ranges from +∞
(maximum attenuation) to the –2 dBu sensitivity (maximum input gain). The centre detent is +4 dBu (nominal level required to
drive the amplifier at maximum power).
4LIMIT INDICATOR. 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 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, continuous operation with the RMS protection active can cause damages to the
speaker.
5SIGNAL INDICATOR. The signal indicator lights green if there is signal present on the main XLR input.
6STATUS INDICATOR. The status indicator lights orange if the main amplifier or power supply is in faulty condition. If the
status indicator lights orange, switch off the amplifier and call the closest RCF SERVICE CENTRE.
7POWER INDICATOR. Power on indicator. When the power cord is connected and the power switch is turned on this indicator
lights green.
8AC POWERCON RECEPTACLE. RCF TT+ series uses a POWERCON locking 3-pole AC mains. Always use the specific power
cord provided in the package.
9POWER MAIN SWITCH. The power switch turns the AC power ON and OFF. Make sure that the sensitivity is set to +∞when
you turn on the speaker.
10 GROUND.
11 LINK XLR OUTPUT. The output XLR male connector provides a loop trough for speakers daisy chaining.
12 AC POWERCON LINK RECEPTACLE. Use this receptacle to link one or more units. Always make sure that the maximum
current requirement does not exceed the maximum admitted POWERCON current. In case of doubt call the closest RCF
SERVICE CENTRE.
13 GROUND.
CONNECTIONS
The XLR connectors use the following AES standard:
PIN 1 = GROUND (SHIELD)
PIN 2 = HOT (+)
PIN 3 = COLD (-)
BEFORE TURNING ON THE SPEAKER
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.
WARNING: Always make sure that the maximum current requirement does not exceed the maximum admitted POWERCON current.
In case of doubt call the closest RCF SERVICE CENTRE.
