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.

INFORMATIONS
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.
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 utilises 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.
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+.
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

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.
