Small like a “mini� array that sounds bigger than a “compact�. Advanced technologies, knowledge, experience, continuous engineering effort and dedication were able to bring us to a unique result: the TL33-A. Active, ultra compact, wide dispersion, line array module that sets a new standard in touring and theatre sound reinforcement.

Digital processing
The integrated digital processor is based on a state of the art 24 bit, floating point DSP running at 96 KHz sampling rate. The calculation capacity largely exceed the processing needs and the DSP is never pushed to the limit. Crossover and equalization of the 6 transducers, limiter, system presets: high pass, air absorption and cluster size corrections.

Digital power
The TTL33-A is powered by a 750 watt switching power supply and 3 digital amplifiers: 500 watt mid-bass , 500 watt midrange and 250 watt compression driver. Very high output, extremely low distortion and natural sound . All the amplifiers and digital processing are housed in an aluminum extrusion external to the cabinet for best heat dissipation.

Compression drivers
A new compression driver unit has been developed in RCF specifically for array applications. The best ratio between the size of the diaphragm and the overall diameter and the very small total size makes the ND1411-MT a unique driver for application in line on straight horns. TTL33-A houses 3 of them for perfect HF control.

Controlled mid-bass
Two light and reliable neodymium 8�, in a band pass loading configuration, provides a tight and loud mid-bass. Thanks to a careful acoustic design the sensitivity in the 100 Hz region is almost double than typical, same size, designs.

High output midrange
A fast and accurate horn loaded 8� takes care of the midrange frequencies. Powerful neodymium magnet, aluminum die cast basket, aluminum back can in direct contact to the rear plate for best heat dissipation.

Reliable mechanics
Laser cut high quality steel bars and precision machining for an easy to use and reliable mechanics. Thanks to the very light weight of the cabinet building the cluster is very simple, fast and effortless.

RCF Prediction Software
In order to assist with the set up procedures for the TTL33-A Line Array System, RCF has developed a complete prediction software package. The software enables a complete two dimensional simulation of the behaviour of the TTL33-A cabinets and also suggests the correct subwoofer combinations.
The system curvature angles and the sound projection data are computed with maximum sound pressure levels for the given building design originally inputted. The software will allow simulations up to a maximum of sixteen TTL33-A mid-high cabinets.
There is also a rigging menu which provides data for weight, centre of gravity and height of the array configuration. Rigging points and rigging hardware configurations are also computed.
