HD 12-A MK4
ACTIVE TWO-WAY SPEAKER
RCF cares about your sound. The new D-Line MK4 speakers boosts the performance with a series of brand new transducers, improves the sound quality with the revolutionary FiRPHASE processing and renew the grille design to exalt the professional look. The vocals are natural, the sound is clear at long distances, the SPL power is stable at very high levels. The concept of the HD-Line derives from the touring industry, bringing in an elegant and compact cabinet all the experience of RCF professional sound with the maximum reliability and strength for the intensive use on the road. Connect your microphone, your device or your mixer to the speaker and turn up the volume: real plug&play. Perfect as a main front of house in small PA systems, high powered floor monitoring and unobtrusive fixed installation.

RCF speakers are designed using a proprietary and advanced digital FiR technology, conceived to deliver transparent sound, absolute clarity and perfect imaging to the listener.
The special FiRPHASE filters allow for coherent distribution of sound for all listeners without phase distortions, ensuring minimum latencies in the system.
The design of the FIR filter for this specific purpose starts from an accurate measurement of the loudspeaker phase.
FiRPHASE algorithm uses this measurement and adapts the loudspeaker’s phase without touching the amplitude equalization. The heart of the advanced technique used by FiRPHASE is a recursive method (least-squares method) combined with a proprietary algorithm that calculates the best FIR filter coefficients set in according to amplitude and phase constraints. The algorithm corrects phase and amplitude (if necessary) by taking into account the weak points of the transducers and the resonances or cancellations due to the cabinet of the loudspeaker. This technique allows a deep control of phase at the mid-low frequency with relatively small filters, reaching a higher resolution than that one as theory suggests.
