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, bracket snot 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.
RCF S.p.A. strongly recommends this product is only installed by professional qualified installers (or specialized 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.
Supports and trolleys.
The equipment should be only 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.
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.).
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

PRODUCT INFORMATIONS

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 transducer and crossover technologies that are superior in acoustic performance and control.
RCF TT+ offers ready to use solutions and tools in true high definition speaker systems.

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 behavior and amplifier operation and the relationship of dynamics and transient response. RCF utilizes over thirty state of the art software packages to identify magnetic circuits, voice coil dynamics, suspension linearity, horn dispersion simulation, crossover filters, amplifier thermal behavior 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 60 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

TT08-A II ACTIVE PRECISION MONITOR

The RCF TT08-A II is by far the smallest member of the TT+ family, whilst being the most flexible and powerful tool in its class. From live sound to playback and monitoring, corporate events and broadcast studios. Though remarkably compact and lightweight, the TT08-A offers an incredible maximum sound pressure level of 128dB. Its performance efficiency is almost 3dB higher than many larger 10” speaker systems and indeed comparable to many 12” systems.

TT10-A ACTIVE PRECISION MONITOR

The RCF TT10-A, with 130 dB SPL and a small footprint, can be the right solution if you need high power and unobtrusive size in live sound, playback or monitoring, corporate events and broadcast studios. Though remarkably compact and lightweight, the TT10-A offers an incredible maximum sound pressure level of 130dB.

TT20-CXA ACTIVE HIGH DEFINITION MONITOR

The TT20-CXA is a full range active high output stage monitor, featuring an high performance symmetrical enclosure. The high frequencies section features a 60° x 90° horn-loaded 2,5” compression driver with constant directivity coverage angle. The Direct Drive technology provides exceptional sound pressure levels, making the TT20-CXA the right choice for medium to large- scale applications. The loudspeaker’s low frequency section comprises two 8” high-power neodymium woofers in symmetrical configuration.

REAR PANEL

FEMALE XLR INPUTS (BAL/UNBAL). The system accepts XLR input connectors.
MALE XLR SIGNAL OUTPUT. The output XLR connector provides a loop through for speakers daisy chaining. The balanced connector is connected in parallel and can be used to send the audio signal to other amplified speakers, recorders or supplementary amplifiers.
SYSTEM VOLUME KNOB
SIGNAL / LIMITER LED. The LED light is green when a signal is applied to the speaker. It turnsRED when the speaker compressor activates.
POWER LED. This green led is ON when the speaker is connected to the main power supply.
LINK LED. This LED turns on when the speaker is connected to RDNet.
ACTIVE LED. This LED blinks when the speaker is transmitting data over RDNet.
RDNET DATA INPUT AND DATA LINK. The RDNET IN/OUT PLUG SECTION features etherCON connectors for the RCF RDNet protocol. This allows the user to completely control the speaker using the RDNet software.
FLAT / HIGH PASS. Use the Flat / High Pass button if you want to apply a Flat or a High Passn Equalization.
BYPASS / LOCAL SETUP. When pressed, the setup is loaded from the internal memory that only RD Net can write. Every time the speaker is turned on, the last stored configuration is applied. When the button is released, the speaker uses its local setup and will not remember its last RD Net setup when turned on again.
AC POWER INPUT. Power con locking 3-pole AC mains.
AC OUTPUT LINK. Power con locking 3-pole AC mains output

WARNING: the Power con connector is used to disconnect the system from the power supply network. It shall be easily accessible after the instillation and during the use of the system

SPEAKER RESET

To reset the speaker to the original settings :

turn on the speaker (the Power LED will blink slowly)
while the Power Led is blinking, press and release several times the Bypass / Local Setup button
the Power LED will now start blinking faster, this means the system accepted the reset command

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.

INSTALLATION

WARNING: daisy chaining speakers 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
WARNING: The power con connector is used to disconnect the system from the power supply network. It shall be easily accessible after the installation and during the use of the system

SERVICE NOTE
