RCF Audio
RCF S.p.A. (formerly Radio Cine Forniture - R.C.F. S.r.l.) is a widely recognized Italian manufacturer of high performance audio products including power amplifiers, loudspeakers, digital mixers and digital signal processors (DSP). History RCF is an Italian audio products manufacturer founded in 1949 in Reggio Emilia. The first products sold were microphones and electroacoustic transducers (loudspeakers). In the late ’60s, concert sound was going electric, and many loudspeaker pioneers were searching for high-powered devices to use in their designs. RCF was one of the first European OEM suppliers for international brands, thanks to the experience built on high power transducers. After a few years, thanks to the in-depth know-how in loudspeaker technology, RCF began to develop and produce sound reinforcement systems under the same brand. The introduction of the ART Series, in 1996, has established RCF among the few global manufacturers of active loudspeakers. The TT+ High De ...

Reggio Emilia
Reggio nell'Emilia ( egl, Rèz; la, Regium Lepidi), usually referred to as Reggio Emilia, or simply Reggio by its inhabitants, and known until 1861 as Reggio di Lombardia, is a city in northern Italy, in the Emilia-Romagna region. It has about 171,944 inhabitants and is the main ''comune'' (municipality) of the Province of Reggio Emilia. The inhabitants of Reggio nell'Emilia are called ''Reggiani'', while the inhabitants of Reggio di Calabria, in the southwest of the country, are called ''Reggini''. The old town has a hexagonal form, which derives from the ancient walls, and the main buildings are from the 16th–17th centuries. The commune's territory lies entirely on a plain, crossed by the Crostolo stream. History Ancient and early Middle Ages Reggio began as a historical site with the construction by Marcus Aemilius Lepidus of the Via Aemilia, leading from Piacenza to Rimini (187 BC). Reggio became a judicial administration centre, with a forum called at first ''Regiu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Line Array
A line array is a loudspeaker system that is made up of a number of usually identical loudspeaker elements mounted in a line and fed in phase, to create a near-line source of sound. The distance between adjacent drivers is close enough that they constructively interfere with each other to send sound waves farther than traditional horn-loaded loudspeakers, and with a more evenly distributed sound output pattern. Line arrays can be oriented in any direction, but their primary use in public address is in vertical arrays which provide a very narrow vertical output pattern useful for focusing sound at audiences without wasting output energy on ceilings or empty air above the audience. A vertical line array displays a normally wide horizontal pattern useful for supplying sound to the majority of a concert audience. Horizontal line arrays, by contrast, have a very narrow horizontal output pattern and a tall vertical pattern. A row of subwoofers along the front edge of a concert stage ca ...

Headphones Manufacturers
Headphones are a pair of small loudspeaker drivers worn on or around the head over a user's ears. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound. Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby to hear. Headphones are also known as earspeakers, earphones or, colloquially, cans. Circumaural ('around the ear') and supra-aural ('over the ear') headphones use a band over the top of the head to hold the speakers in place. Another type, known as earbuds or earpieces consist of individual units that plug into the user's ear canal. A third type are bone conduction headphones, which typically wrap around the back of the head and rest in front of the ear canal, leaving the ear canal open. In the context of telecommunication, a headset is a combination of headphone and microphone. Headphones connect to a signal source such as an audio ...

Electronics Companies Established In 1949
The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow. Electronics has hugely influenced the development of modern society. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $481 billion as of 2018. The largest industry sector is e-commerce, which generated over $29 trillion in 2017. History and development Electronics has hugely influenced the development of modern society. The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small electr ...

Linear Phase
In signal processing, linear phase is a property of a filter where the phase response of the filter is a linear function of frequency. The result is that all frequency components of the input signal are shifted in time (usually delayed) by the same constant amount (the slope of the linear function), which is referred to as the group delay. Consequently, there is no phase distortion due to the time delay of frequencies relative to one another. For discrete-time signals, perfect linear phase is easily achieved with a finite impulse response (FIR) filter by having coefficients which are symmetric or anti-symmetric. Approximations can be achieved with infinite impulse response (IIR) designs, which are more computationally efficient. Several techniques are: * a Bessel transfer function which has a maximally flat group delay approximation function * a phase equalizer Definition A filter is called a linear phase filter if the phase component of the frequency response is a linear func ...

Powered Speakers
Powered speakers, also known as self-powered speakers and active speakers, are loudspeakers that have built-in amplifiers. Powered speakers are used in a range of settings, including in sound reinforcement systems (used at live music concerts), both for the main speakers facing the audience and the monitor speakers facing the performers; by DJs performing at dance events and raves; in private homes as part of hi-fi or home cinema audio systems and as computer speakers. They can be connected directly to a mixing console or other low-level audio signal source without the need for an external amplifier. Some active speakers designed for sound reinforcement system use have an onboard mixing console and microphone preamplifier, which enables microphones to be connected directly to the speaker. Active speakers have several advantages, the most obvious being their compactness and simplicity. Additionally the amplifier(s) can be designed to closely match the optimal requirements of th ...
