TT 4-A - THE SPEAKER SOLUTION

Top quality sound for very demanding situations indoors or outdoors in small to medium-sized areas. The flexibility of the TT 4 series fills the gaps between point source and linear array loudspeakers, and gives sound engineers increased adaptability. This approach combines all the benefits of TT+ technology such as controlled dispersion, outstanding clarity and extreme power with three coverage options, multiple rig accessories, remote control and storable presets. A ground-breaking solution for a wide range of applications. 

100° X25° WAVE GUIDE WITH FREQUENCY-EVEN DIRECTIONALITY

This special wave guide construction allows multiple TTL 4-A's to be deployed for excellent control of directivity. In difficult acoustic environments, clarity in the speech area is increased considerably. 

RCF RDNET

NETWORK CONTROL AND MUCH MORE
RDNet is a robust control network and control platform for small, medium and large sound systems, as well as complex installations. Based on a self-developed network protocol, RDNet provides intuitive control and monitoring of all connected devices / objects in the RCF sound system. Each device has DSP to address specific presets or changes of parameters to individual or groups of objects. A network user can change level, delay, EQ (linear phase - FiR too) and other settings, including advanced subwoofer configurations. RDNet is not only designed for speakers - you can control the parameters and routing of multiple RCF devices, such as digital matrices or amplifiers. 

NEW PERSPECTIVE ON LINEARITY

RCF loudspeakers are designed with a proprietary and advanced FiR filtering technology, designed to deliver transparent sound and perfect stereo imaging to the listener. 
The special FiRPHASE filters make it possible to achieve even sound distribution for all listeners without phase distortion, which ensures minimum delay.
