White Paper Utopia & Elear White Paper
UTOPIA & ELEAR WHITE PAPER UTOPIA & ELEAR WHITE PAPER Focal’s DNA is, by essence, the com- bination of the absolute acoustic quest, total control of the manufacturing process and the “je ne sais quoi” brought by the com- pany’s designers into every single product. The extreme care paid to each detail, from the early stages of R&D, to utilizing the latest manufactu- ring techniques and thorough quality control sums up our philosophy. Since the very beginning, Focal has brought major innovations that pushed the limits of loudspeakers and their performance, thanks to the flagship pro- jects within the brand such as, Utopia III, Utopia Be car audio kits or SM9 studio monitors. During the development of these flagship products in each of their respective divisions, the amount of time and resources devoted to the research phase far ou- tweighed the actual production. These products were “born” thanks to this approach in order to reach the ultimate acoustic truth. > Grande Utopia EM > SM9 > Ultima kit UTOPIA & ELEAR WHITE PAPER However, to keep on innovating and to reach such a target requires a different way of thinking. We needed to be able to capitalize on our core know-how and past experiences, but also to challenge traditional thinking of what is possible and what could be achieved. This strategy resulted in the creation of numerous > "W" composite exclusive technology, such as “W” composite sandwich sandwich cone cones or IAL tweeters that brought major improvements in term of acoustic translation of the original audio signal. Before starting on the Focal flagship headphone project, we already had the relevant background with our in-house knowledge, thanks to the well-received Spirit headphone line. -
The Frequency Element: Using the Equalizer
Chapter 7 The Frequency Element: Using The Equalizer Even though an engineer has every intention of making his recording sound as big and as clear as possible during tracking and overdubs, it often happens that the frequency range of some (or even all) of the tracks are somewhat limited when it comes time to mix. This can be due to the tracks being recorded in a different studio where different monitors or signal path was used, the sound of the instruments themselves, or the taste of the artist or producer. When it comes to the mix, it’s up to the mixing engineer to extend the frequency range of those tracks if it’s appropriate. In the quest to make things sound bigger, fatter, brighter, and clearer, the equalizer is the chief tool used by most mixers, but perhaps more than any other audio tool, it’s how it’s used that separates the average engineer from the master. “I tend to like things to sound sort of natural, but I don’t care what it takes to make it sound like that. Some people get a very preconceived set of notions that you can’t do this or you can’t do that, but as Bruce Swedien said to me, he doesn’t care if you have to turn the knob around backwards; if it sounds good, it is good. Assuming that you have a reference point that you can trust, of course.” —Allen Sides “I find that the more that I mix, the less I actually EQ, but I’m not afraid to bring up a Pultec and whack it up to +10 if something needs it.” —Joe Chiccarelli The Goals Of Equalization While we may not think about it when we’re doing it, there are three primary goals when equalizing: To make an instrument sound clearer and more defined. -

Acoustic feed back: The sound from the loudspeakers should not reach microphone. It may result in loud howling sound. Distribution of Sound Intensity: Instead of installing one or two powerful loudspeakers near the stage alone, audio power should be divided between several loudspeakers to spread it right up to the farthest point. This covers every specified area. Reverberation (Echo): Install several small power loudspeakers at various points to get rid of problem of overlapping of sound waves in the auditorium, rather than using single power high power unit. 29/01/2019, USJ Basic Requirements of PA System: . Orientation of speakers: The loudspeakers be oriented as to direct the sound towards the audience and not towards walls. The loudspeakers should preferably be placed a meter off the floor, so that their axes are about the height of the ears of the listeners. Selection of Microphone: Microphone for PA system should be preferably cardiod type, it will prevent reflection of sound from loudspeakers. For dramas use directive microphone. -

A Nearly Complete Case for the Horn Beginning with the Driver High
Earo High Definition Audio A nearly complete case for the horn This paper attempts to describe , in least complex scientific terms, the challenge of converting an electrical audio signal to an acoustic one. In doing so it also attempts to explain the rationale behind the principles of horn loading and why Earo bases most of its designs on this method. Beginning with the driver You are invited to join in on a jo urney that will take you to some insights on why speakers are designed they way they are and why old school wisdom can be combined with state of the art technology to create outstanding realism in audio reproduction. We need to begin where the rubber hits the tarmac, with the loudspeaker driver. It appears to be simple in concept and implementation, that’s deceptive as we will show. In the picture below we can structure the speaker into two significant section, the frame and the moving parts. The frame consis ts of the basket which is the driver chassis. It holds the magnetic circuit and the two flexible joints that allow the moving parts to move. The lower moving part both cent ers and acts as a return spring to the cone assembly. It is termed “spider” which is strange as it does not resemble one at all. At the other end of the cone is the other joint suitably termed the “surround” . We won’t dig too deep into the exciting world of the magnetic circuitry and will rest to say that regardles s of what source of magnetism is used, its purpose is to direct as much as possible of it into a circular airgap in which the voice coil moves.
