RCF HD 12-A mk4 700W 12" Digital Active Speaker (EACH)

The HD 12-A mk4 active speaker provides a rich low-end with a deep punch, as well as a clear mid-range and crisp top-end. This makes it ideal for a number of applications, from live sound, playback, stage monitoring or installations.

The integration of FiRPHASE technology ensures that a highly transparent sound with amazing clarity is delivered. This is an advanced filter, and the FiRPHASE algorithm enhances dynamics, amplitude and phase patterns, making sure that there is minimal latency.

Pure Class D Power:

The HD 12-A mk4 provides you with incredible audio quality, thanks to its high-quality materials and a Class D amplifier. This offers a bold sound that can fill large venues, with a quick attack and balanced response.

A strong aluminium structure for the amplifier ensures great stability and protection, meaning that the speaker will run reliably with less risk of overheating as it dissipates any high temperatures.

Solid Construction:

The HD 12-A mk4 enclosure is moulded on a polypropylene composite material, forming a solid and wear-proof casing. This not only means that the speaker can survive gig after gig, but it also dampens vibrations to provide cleaner audio delivery.

Featuring 3 handles (top and side-mounted), transporting the HD 12-A mk4 is made easy, and its light weight lessens the risk of injury when carried. A robust steel pole mount underneath the speaker means you can position the speaker in a standard configuration or as a stage monitor, run it however you prefer!

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.

THE LATEST EVOLUTION IN THE ACTIVE LOUDSPEAKER TECHNOLOGY
The concept of this unique speakers derives from the touring industry, bringing in a compact cabinet all the experience of RCF professional sound.
The RCF Team always has the performer’s needs at the forefront of the design in order to create new lines of speakers with renewed features, improved sound clarity and definition and even lighter weight systems.
D-LINE represents the  latest evolution in the active loudspeaker technology with a revolutionary design and sound. Every detail has been carefully studied in order to offer musicians and professionals the perfect tool to amplify their performance, night after night.
High quality materials, precise manufacturing, careful assembly and extensive quality control procedures complete the groundbreaking design work of the RCF R&D team.
The vocals are natural, the sound is clear at longer distances, the spl power is stable at very high levels.

RENTAL PROOF
D LINE cabinets are moulded on a special polypropylene composite material designed to dampen down vibrations even at maximum volume settings. From moulding to the final texture, D-LINE offers the maximum reliability and strength for the intensive use on the road. The reflex port has been resized to offer a better efficiency.
The HD 32-A is equipped with a top handle and a side handle with rubber handgrip for greater portability.
The RCF HD 12-A features 3 ergonomically designed forged handles with rubber handgrip, 2 on the sides and one at the top.
The HD 10-A is equipped with a top handle and a side handle with rubber handgrip for greater portability.
At the bottom a rugged steel pole mount has been installed in all models.
The new cabinet shape will allow every D-LINE model to be used in the standard configuration as well as in stage monitor model. Two M10 and 3 M6 threaded inserts are provided for optional mounting hardware in Installed Sound Applications.

POWERFUL CLASS D AMPLIFIERS
RCF's Class-D power amplifier technology packs huge performance operating with high efficiency into a lightweight solution. D-Line amplifiers deliver ultra-fast attack, realistic transient response and impressive audio performance. The amplifier features a solid mechanical aluminium structure which not only stabilises the amplifier during transportation but also helps the fan-less heat dissipation. All the D-LINE amplifiers present SMPS power supply section in order to produce maximum output and minimum transportation weight.

A NEW PERSPECTIVE ON LINEARITY
RCF speakers are designed by using FiRPHASE, a proprietary and advanced FIR filtering technology, conceived for delivering transparent sound, absolute clarity and perfect stereo images to the listener. The FiRPHASE algorithm optimizes dynamics, amplitude and phase patterns, ensuring at the same time minimum system latency.

IN/OUT CONNECTORS
The amplifier presents both XLR In/Out connectors and a Jack input for the maximum connection versatility.

SWITCHABLE EQ MODE
A switchable EQ Mode makes it easier to select among two different equalisation presets:
- Extended response switch that slightly emphasizes the bass response for playback music and low volume applications;
- Linear response switch, when the speaker is used to amplify a live mix. The amplifier has a built in limiter circuit to prevent clipping or overdriving the transducers.

MIC/LINE SWITCH
A useful Mic/Line switch helps adjusting the input sensitivity. When used for speech, the [Mic] setting allows to use a microphone directly with the speaker. Set the selector to [Line] when using the speaker for live music or playback.

VOLUME KNOB
An easy to reach volume knob on the back allows to set the overall volume of the speaker according to its application.

STATUS LEDS
3 status LEDs – Power / Signal / Status are provided for monitoring the system.

SUPERIOR DRIVERS
At the core of HD 12-A there are the best quality components, starting from the powerful with 1” voice coil and 1.5”diaphragm compression driver. This allows better coverage, dispersion control and incredible efficiency.
The 12” woofer offers an extremely linear response and a precise, deep low frequency control. All the compression drivers and transducers are precision built, taking advantage of RCF’s superior knowledge and experience dedicated to achieving extremely high standards.

FIRPHASE
RCF speakers are designed by using FiRPHASE, a proprietary and advanced FIR filtering technology, conceived for delivering transparent sound, absolute clarity and perfect stereo images to the listener. The FiRPHASE algorithm optimizes dynamics, amplitude and phase patterns, ensuring at the same time minimum system latency.

PHASE MATTERS
The design of the FIR filter for this specific purpose should start from an accurate measurement of the loudspeaker phase. The 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 Squared 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 (when necessary) by taking into account the weak points of the transducers and the resonances or cancellations due to the cabinet of the loudspeaker. Despite the design perfection of our transducers and cabinets, we realize that the phase corrections are the “missing point” for the perfection. This technique allows a deep control of phase at mid-low frequencies with relatively small filters, reaching a higher resolution than that one as theory suggests.
