RCF ART 725 MK4 [5/12] Rear panel features and controls

ENGLISH

INPUT is a Neutrik Speakon connector for connecting a speaker-level signal.

OUTPUT is a Neutrik Speakon connector, paralleled with the INPUT jack, for daisy-chaining speakers together.

The Speakon connectors use the following wiring standard:

Pin 1+ = Signal (+)

Pin 1- = Ground (-)

ART was originally conceived back in 1996. The brief was a tough one: creating a perfect sound. Moreover, the speaker enclosures had to be

portable, lightweight and strong enough to withstand an every day use. Using the latest “Advanced Resource Technology’’ the brief remains

the same, but with even more exicting challenges. Creating portable and even lightweight systems with improved vocal clarity and deﬁnition

were RCF goals since the beginning.

INSTALLATION

A 35 mm socket for mounting the loudspeaker on a speaker stand is provided on the bottom of the cabinet.

ART speakers MUST be suspended only with approved rigging hardware. In any case always use at least 2 M10 threaded inserts on

apposite sides of the cabinet.

The new ART SERIES is a range of professional active speaker systems combining high power and wide bandwidth in a light weight enclosure.

COMPONENTS

The woofers used in ART 725 MK4 can withstand peak power of up to 6 times the nominal power. This mid bass woofer has been designed

for superior reproduction of acoustic signals up to the crossover frequency.

Speciﬁc attention has been applied to the speaker cone, optimized for shape and pulp composition.

Our edgewound copper clad aluminium voice coil provides maximum efﬁciency and high speed for accurate transient response.”lnside /

Outside” copper clad aluminium voice coil provides maximum reliability.

ART 725 MK4 massive magnet offers superior bass control and mid-bass voice presence. Our state of the art compression driver is made from

neodymium magnetic circuit technology, reaching levels that exceed 2 Kilogauss in the gap. Thanks to the RCF ”pure titanium” diaphragm

and proprietary high pressure oxygen free moulding technology, we are able to reproduce transparent and accurate high frequencies in all

the audible range.

LICC LOW IMPEDANCE COMPENSATED CROSSOVER

ART 725 MK4 is equipped with a high power handling low impedance crossover design. The low impedance compensated crossover represents

an RCF breakthrough in crossover design. Conventional passive crossovers have an approximate 180 degree phase shift between the woofer

and tweeter at the crossover point. Such a system cannot reproduce transients correctly, causing negative effects on sound accuracy that are

particularly noticeable with violin, trumpet, piano and vocals. Very low inductance values are used in the LICC™, thus providing an excellent

transient response and drastically reducing phase shifts between the woofer and the tweeter. As a result, LICC™ provides a well-deﬁned

natural and open sound across the entire audio bandwidth.

CABINET

ART 725 MK4 polynomial constant directivity horn has virtually the same physical area as a the woofer. This means the driver is perceived to

achieve the same output power as the low section with minimum diaphragm excursion, resulting in a well deﬁned, natural and open sound.

The horn shape is a unique design able to provide exceptional constant directivity with the compression driver.

ART 725 MK4 bass reﬂex cabinet is moulded in a special polypropylene composite material resulting from years of experience in plastic

cabinet designs, providing superior stiffness, lightweight and excellent low frequency damping.

The cabinet is equipped with ergonomically designed handles on each side and a comfortable top handle for easy manoeuvrability in every

situation. Four M10 threaded inserts are provided for optional mounting hardware in lnstalled Sound Applications.

WARNING: Never suspend ART speakers by their handles. Handles are intended for transportation, not for rigging.
