RCF HDM 45-A - ACTIVE TWO-WAY PROFESSIONAL SPEAKER

The HDM 45-A speaker boosts the performance with a top-quality two channel amplifier, RDNet networked management, RCF precision transducers, the FiRPHASE processing, and a rugged cabinet. While being one of the most powerful speakers in composite material in its category, it delivers clear, detailed and smooth sound from low to very high levels, with low distortion and fast transient response. The HDM concept is inspired by the touring industry, packing in an elegant and lightweight cabinet the maximum reliability and strength for intensive use on the road. Perfect as a main front of house speaker in PA systems, high-powered floor monitor, or unobtrusive infill system when combined with the RCF HDL System speakers.

RCF RDNet - Networked Control and Much More

RDNet is a robust management network and control platform for small, medium and large arena-sized sound systems, as well as complex and extended installations. Based on a proprietary network protocol, RDNet provides intuitive control and monitoring of every connected device/object in the RCF audio system. Each device has DSP to address specific presets or modifications of parameters to single or groups of objects. A network user can change level, delay, EQ (linear phase FiR as well) and other settings, including advanced subwoofer configurations. RDNet is not only designed for loudspeakers—you can control parameters and routing of multiple RCF devices, such as digital matrixes or amplifiers.

POWERFUL CLASS-D AMPLIFIERS

Constant linearity from very low-level signals to the maximum amplifier output. A 32-bit floating-point DSP with 48 kHz processing takes care of:
- 2-way crossover and transducer alignment
- 8 programmable equalizations
- Programmable output time delay
- Input Sensitivity reduction
- Soft limiter for very high signal inputs
- RMS monitoring and transducer protection
- Input noise reduction
A specially developed algorithm takes care of the frequency dependent soft limiter offering to the listener the same linearity of the system, from very low-level signals to the maximum amplifier output.

LEGENDARY TRANSDUCERS

- The ND940 Compression Driver in pure Titanium with a 4 inches voice coil allows a crossover point at only 650 Hz. This allows a better impulse response, fast decay, and superior efficiency. Lightweight and powerful, RCF neodymium drivers are a reference in performance and reliability.
- The low-frequency transducer is a high-power 15’’ neodymium woofer with a 3.5’’ voice coil that delivers tight, punchy bass. Reproduction of the mid-bass frequencies is accurate, transparent, and free from distortion.

NEW PERSPECTIVE ON LINEARITY

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.

RENTAL PROOF

D LINE cabinets are molded with a special polypropylene composite material designed to dampen vibrations even at maximum volume settings. From molding to the final texture, D-LINE offers maximum reliability and strength for intensive use on the road. The advanced vented architecture offer high efficiency and low distortion. The speaker is equipped with a top handle and two side handles with rubber handgrips for greater portability.

HIGH DEMAND APPLICATIONS

The multi-purpose cabinet shape will allow every D-LINE model to be used in the standard configuration as well as in stage monitor mode. Two M10 and three M6 threaded inserts available for optional mounting hardware. This makes the speakers perfect for use in mounted or flown situations. When used on top of a SUB Series the HD speaker becomes an incredibly powerful PA system.
