RCF 4PRO High-Performance Loudspeakers

Plug your favourite microphone into any 4PRO System and immediately experience the accurate voicing.

If you have had the opportunity to listen to any RCF active systems live in the past, then you will, hopefully be enthusiastic about the new 4PRO Series. The system represents a natural evolution of what RCF has produced in the past. This progression has now reached the 4PRO system, dedicated to live, touring and fixed installations. As with all RCF developments, it comes out of a desire to improve on what has gone before. In doing so, RCF first listened to what its customers said, it is from this feedback, that RCF has strived to produce the perfect speaker.

Over the past years, of continuous research and development of active technology, RCF have reached a whole new audience in the live PA and concert market. In doing so, one thing has become evident, in both large and small live music venues, with their professionalism there is a passion to produce something more – the sound that gives you the possibility of creating new emotions.

Active speaker technology is a cost effective solution when produced correctly. It is only by the checking of every single transducer, signal processor that is used in the speakers, plus Real time control circuits that take care of the audio chain and status of the electronics, monitoring the temperatures of heat sinks that you arrive at designing the most reliable and acoustically correct active designs. RCF is not only a pioneer in this field but a true market leader.

4PRO is designed for professionals, who have always loved RCF speakers and have looked for the perfect marriage of specific power amplifiers with the appropriate crossover or active processor.

Components

It is the acoustic designs that have made RCF the transducer company of choice for many of the world’s leading professional audio brands. For the design of 4PRO, RCF has not only used all new high frequency drivers which are part of the high performance RCF and the well known RCF 18" woofer, but after 2 years of research, RCF has finally produced a new “state of the art” midrange unit.

The compression driver is the very latest in neodymium magnetic circuit technology, reaching levels that exceed 2 Kilogauss in the gap. The “pure titanium” diaphragms are able to reproduce transparent and accurate high frequencies, true to all the audio range. This is thanks to RCF’s proprietary high pressure oxygen free moulding technology.

The low frequency drivers used in the 4PRO Series can withstand peak power of up to six times the nominal power. These mid bass woofers have been designed for superior reproduction of acoustic signals up to the crossover frequency.

Amplifiers

All the 4PRO models are designed using newly created RCF ‘True Active Extended Dynamics ‘TAED’ Active Amplifier Technology. Each amplifier has a specific input board and set-up to optimise the performance in conjunction to the specific transducers in each model. Each amplifier will give you: combo Jack/XLR balanced inputs, XLR Output link, protected gain control, Powercon® Mains Input. Each subwoofer amplifier is equipped with mono/stereo inputs, protected gain control, low pass filters, mono/stereo crossover outputs, crossover frequency selection switch and phase control switch.
