RCF HDM45A:
Power, Poise & Portability

RCF powered, portable PA speakers are already trusted by working professionals – and have been since the first ART300A rolled out of the factory door back in 1996.

They have now ratcheted things up another couple of levels with the introduction of the top-of-the-tree D-Line series speaker – HDM45A.

Powerful, Portable Point Source

It’s not just powerful – HDM45A is peerless when it comes to powered, point source speakers for Front-of-House, side-fill, stage monitoring or delay lines.

Before we get stuck into the components that make HDM45A such a perfect match for large spaces as part of your hard-working inventory, let’s check why RCF is so excited to call this the “rental proof” PA speaker.

Rental proof

Like the other D LINE speakers in the range, HDM45A cabinet is moulded with a special polypropylene composite material designed to dampen vibrations – even at maximum volume settings.

From moulding to the final texture, HDM45A offers maximum reliability and strength for intensive use on the road. The advanced vented architecture offer high efficiency and low distortion.

To make lugging nice and easy, there is a top handle and two side handles (all with rubber handgrips).

On-board Amplifier & DSP

RCF has never been shy of “chucking the kitchen sink” into the power section of their active PA speakers.

Let’s have a quick dig:

Total Power: 2200 W Peak (1100 W RMS)
High frequencies: 600 W Peak (300 W RMS)
Low frequencies: 1600 W Peak (800 W RMS)

A 32-bit floating-point DSP with 48 kHz processing takes care of:

• 2-way crossover and transducer alignment
• 8 programmable equalisations
• 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 linearity of the system, from very low-level signals to “full bottle”.

Event company : Hire inventory : Step it Up

You may be in charge of corporate event production delivery, or you may be running a DJ hire company – it comes back to the same thing though.

It’s much easier to keep your existing clients happy (and returning) than it is to go and find new clients.

If your customers are happy, the chances are they will not only return, but will help refer more clients your way.

While a quick google search for “keeping clients happy” doesn’t actually list “keep RCF HDM45A in your inventory” as a key point, it should!

These speakers not only look the part, but they’re capable of filling a large space with clear, undistorted sound.

Just in case you don’t know, RCF = Legendary Transducers

If you’re new to Factory Sound, you might not kept up with our RCF fanboy history, but it’s been well-entrenched since the ’90s.

The Italian-made components have been sought after by other manufacturers since 1949 – although when RCF began making their own ‘finished boxes’ during the 1990s, they became a (very) serious competitor to other brands, and less of a “gee, they make great components” company.

Here’s what RCF has to say about their Legendary transducers for HDM45A:

Superior compression drivers

The ND940 Compression Driver in pure Titanium with a 4″ 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.

Direct drive technology

The voice coil features a high-temperature kapton former. The assembly process takes advantage of the RCF proprietary Direct Drive technology. The diaphragm’s suspension has been designed following extensive studies aimed at minimising distortion and extending low frequency range.

Potent woofer

The low-frequency transducer is a high-power 15’’ neodymium woofer with a 3.5’’ voice coil, delivering a punchy bass. Reproduction of the mid-bass frequencies is accurate, transparent and free from distortion.

If you want to slip a little deeper into just what makes RCF precision transducers so good, they’ve got a nice page here with a bit of detail. Since 1949, RCF has been at the forefront of speakers that deliver what they promise.
