RCF extends power to 4K

The HDL 50-A 4K can enhance the SPL up to 143dB

The Italian manufacturer has added to its HDL composite range with the HDL 50-A 4K, an active three-way line array module redesigned from the original HDL 50-A. It is charged with 8,000W peak power and comes with two 12-inch woofers, four symmetrical 6.5-inch midrange and two 2-inch drivers. The module can enhance the SPL up to 143dB. FiRPHASE and RDNet 3.1 networked management are also included. The housing is constructed from lightweight plywood and polypropylene and the unit weighs 56kg. Current HDL 50-A owners can upgrade the system to 4K by replacing the onboard amplifier.

Staying with the HDL range, the HDL 36-AS is described by RCF as the ideal flyable bass complement for the HDL 28-A array system. It features one 4-inch voice coil and a 15-inch neodymium woofer to handle 135dB SPL max from 40–140Hz. The built-in 3,200W Class-D

amplifier delivers playback clarity up to 135dB SPL max. It is also compatible with RDNet remote monitoring and control.

Following customer requests for a companion 10-inch system for the NX series, RCF has reworked the NX 10-A platform to develop the NX 10-A II. Powered by internal two-way 1,400W Class-D amplification, it comes in a solid aluminium structure, which is said to stabilise the amplifier and assist with heat dissipation. The DSP has limiters and protection, as well as FiRPHASE filters to boost coherent distribution without phase distortion. The NX 10-A II is loaded with a 10-inch woofer with a 2.5-inch voice coil and 1.75-inch compression driver, with 1-inch voice coil assembly.


RCF has also introduced the MC-1 Monitor Controller, designed to manage two pairs of stereo monitors. The controller features two stereo inputs on combo connectors (TRS+XLR) on Input A and TRS jack and mini-jack on Input B, as well as two pairs of XLR for output. Also featured is a DIM (mute) button, reducing the sound by –20dB, a mono switch and a central generous machined main volume control. The MC-1 is passive and requires no external power.

Following a complete firmware redesign with improved sound, enhanced precision and 0° phase response, RCF has upgraded its TT 5-A II, TT 2-A II, TT1-A II, TT 051-A II and TT 051-A II models. RDNet network connection now embeds all the TT+ speakers and allows FiRPHASE technology. Older models can be upgraded by installing the optional RDNet board and running a firmware upgrade from the RDNet software.
