TTL33 WP
PASSIVE LINE ARRAY MODULE
DESCRIPTION
The TTL33 WP is a full range, ultracompact, wide dispersion, line array module
that sets a new standard in the touring and theatre sound reinforcement,
offering substantial power and efficiency for a variety of professional indoor
or outdoor applications. TTL33 WP is a 3-way passive system featuring with 2
x 8” neo woofer 64 mm voice coil in a bandpass low frequency configuration,
1 x 8” neo midrange 64 mm voice coil in horn loaded configuration, 3
x 1” neo compression driver 37 mm voice coil, titanium dome, in hornarray configuration. Each transducer has been specifically designed for the
application. The 2 woofer provides large excursion and very light weight, the
midrange has an incredibly high BL for best vocal presence, the unique
compression driver design offer the minimum spacing between throats to
avoid HF cancellation.
Thanks to the extensive use of neodymium and new basket designs, the total
weight of the 6 transducers is less than 8 Kg!
The internal passive filter provides crossover and equalization between
the midrange and the compression driver. The Crossover network offers
Compression Driver Protection thanks to a unique design Active MOSFET
Circuit. The system is driven in bi-amped mode, is able of producing a Max
SPL of 133 dB and handles 500 Watts AES (LF) + 200 Watt AES (MF/HF)
TTL33 WP includes the LICC-Low Impedance Compensated Crossover that
features markedly lower induction values in series with the woofer. The benefit
is delay reduction, reduced phase shift and superior transient response. For a
superior power handling high power, aluminium case, resistors are used in the
crossover network. Dynamic high-frequency driver protection is accomplished
with the RCF exclusive – Active Mosfet Compression Driver Protection System,
chosen to complement the power curve of the driver.

MAIN APPLICATIONS
• Outdoor sound reinforcement
• Touring sound reinforcement for mid-sized venues
• High quality reinforcement of music and speech
• Medium to large theatres and night clubs
• Stadiums, arenas, concert halls and other fixed venue installations
• Corporate A/V presentation
Connections to the amplifier are made through a watertight multi-pole
connector IP67. The grille is in custom perforated aluminum with open-cell
fibers and water repellent woven fabric backing.
The cabinet is constructed of multi-ply baltic birch plywood and finished in a
very resistant, textured, polyurea black paint. The mechanical suspension and
orientation system is in high quality steel, very precise and easy to use. The
suspension system is directly connected to the aluminum sides of the cabinet.
The suspension system is designed to have a safety factor 7 up to 16 speakers
per side.
