INTRODUCTION
The TTL33-A and TTL31-A are the active line array mo-
dule of RCF TT+ family. The TTL33-A and TTL31-A are
a full range, ultracompact, wide dispersion, line array
modules that sets a new standard in the touring and
theatre sound reinforcement.
Thanks to digital amplifi ers, high power neodymium transducers and well designed cabinet and mechanics the TTL33-A
and TTL31-A are unique products and offers the maximum output per size and weight; acoustically are “fully horn
loaded” in order to properly control directivity and to provide the highest sensitivity. The system is very easily confi gura-
ble; the cabinet is 15° shaped and is possible to build very small fl own clusters starting from 4 modules or very big, long
throw, systems of 16 modules. A 32 bit fl oating point DSP, sampling at 96 kHz, is taking care of system equalization, 24
db/oct crossovers, soft clipping and system confi guration parameters like air absorption or cluster size correction.
TRANSDUCERS TECHNOLOGY
Each transducer has been specifi cally designed for the application. The woofer provide large excursion and very light
weight, the midrange has an incredibly high BL for best vocal presence, the unique compression driver design offers 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 transducers is negligible!
TTL33-A 8” NEO WOOFERS
The MB8N251 is a high output, high power handling mid-bass desi-
gned to provide a very tight and fast response in band-pass designs.
Extended response down to 60 Hz, inside-outside voice coil, M-roll
surround. The voice coil size is 2.5”.
The TTL33-A is equipped with 2
