RCF Improves Touring & Theatre Line with RDNet, FiRPHASE and Three-Product TT 4-A Series




New TTL/TTW/TTP 4-A Family Offers Multi-Configuration and Control, With Rotatable Waveguide, FiRPHASE and RDNet on Board


RCF continues to improve its flagship Touring & Theatre products, infusing them with RDNet and FiRPHASE as standard, and it has also extended the range, notably with the three-product TT 4-A series. The new series has been designed to deliver top quality sound for highly demanding events, both indoors or outdoors, and for small to medium sized areas.

TTL 4-A (line array), TTW 4-A (wide dispersion) and TTP 4-A (point source) are equipped with 2 x 10” LF woofers and high performance 4.0" compression driver on a rotatable/swappable waveguide. The TTL 4-A waveguide is 100° x 25°, the TTW 4-A offers 100° x 50° dispersion and the TTP 4-A is 60° x 25°. All models are powered by 2 x 1600W Class D amplifiers.

Due to the advanced rigging and 90° rotatable waveguide the series offers infinite possibilities. The TTL 4-A’s rotatable waveguide can be moved from the upper to the central position—swapping the woofer, and allowing the speaker to be arranged in vertical array or constant curvature clusters with up to six modules.



The TTW 4-A can used alone to generate a 100° x 50° homogeneous coverage, stacked/flown in a column or arranged in constant curvature clusters with up to four modules, the rotatable horn allowing the speaker to be used in both the vertical or horizontal planes.

The TTP 4-A elements can be used individually to generate a 60° x 25° homogeneous coverage, flown in a column or constant curvature clusters—again with vertical or horizontal orientation, with up to six modules per line.  This offers flexibility to rental companies as these enclosures can either be run in series or intermixed.

All are equipped with FiRPHASE 0° linear phase and RDNet as standard. In fact, RCF now has five products with FiRPHASE and RDNet plugin fitted to its TT+ series.

New Firmware and RDNet on TT+ Series Speakers

RDNet network connection embeds now all the TT+ speakers and allows FiRPHASE technology. Older models can be upgraded by installing the optional RDNet board and then running a firmware upgrade from the RDNet software.
