By psychologists it is proved, that music, illumination, ventilation, beautiful laying - the major factors of influence on the visitor.
High quality of a soundtrack and acoustics of a hall - the mortgage of high-grade rest and a guarantee of high reputation of an institution. Especially cenen at restaurant a "alive" sound, that is the compositions played by musicians without a soundtrack at presence of visitors. However the organization at restaurant of a high-grade concert platform - employment completely not simple also demands considerable material inputs.

With what to begin...
At once we shall make a reservation: now creation of the competent acoustic project of restaurant on forces only to professionals. Therefore, if you do not want, that during visiting your institution visitors received all scale of the sensations peculiar to rural discos, it is better to address at once in this or that company, engaged installation of the sound equipment.
In Moscow tens the firms offering similar services today work, however even among them to find experts of a high level not so simply. Starting a choice of firm-executor, it is necessary to pay the most steadfast attention to an operational experience, quantity and, that the most important, quality of the executed projects, a spectrum guarantee and poslegarantiinyh services. The serious companies provide even preparation of the personnel of an institution which will be in direct contact to the sound equipment.
To postpone with search of the firm incuring the responsibility for selection, installation and adjusting, it is not necessary even in the event that construction of restaurant has not begun yet. Features of acoustics of premises are formed at a stage of outline designing of a building in which it is supposed to place restaurant. Thus civil engineers, as a rule, do not reflect on such "trifles", as a sound. It is possible to cite as an example weight of restaurants and the cafe, equipped by the expensive equipment which opportunities are not used to the full owing to a wrong lay-out of a hall. Therefore it is desirable, that building and sound projects have been coordinated at the earliest stage of life cycle of an institution.
If your restaurant works already for a long time and differs really unique interior and furniture of premises, but sound registration in it while is absent, services of experts on installation of a sound it can appear insufficiently. It is necessary to address for the help to the designer who is made out interiors and if it is impossible - to professional artists and architects. Only with their help for certain it will be possible to pick up the technics ideally corresponding style.
After the coordination of the technical project the firm-executor starts to work, during which can be carried out a sound computer breadboard model of a hall with tables and a stage, to be spent so-called modelling the empty and filled hall, its separate points, etc. Process of installation are listened, as a rule, has interactive character: various variants of the decision of this or that problem are offered the customer, the opportunity of realization of those or other technical ideas is discussed.
It is necessary to note, that installation of the sound equipment almost always is spent in parallel with other works: furnish of restaurant is a complex technological problem above which decision some subcontractors work at once. In order to prevent annoying misunderstanding it is necessary to watch that interests of various experts were coordinated in due time. A characteristic mistake, their resulting inconsistency, irrational, mutually exclusive accommodation of light devices and the sound equipment is.
Practice shows, that during work the initial project can transform beyond recognition, and, as a rule, in the best party. And in it there is nothing surprising: creative people are engaged in installation of the equipment in most cases. However, last circumstance sometimes results and in some overlays, to avoid which it is possible only at presence of the rigid monitoring system behind performance of works and stipulated in advance penal sanctions.

And than to finish...
Almost all the firms, engaged installation of a sound in bars and restaurants, offer the customer the musical goods of only several manufacturers by virtue of what selection of the equipment necessary for your restaurant can have subjective character. Therefore the general representation about components of " good music " to have it is necessary.
In the beginning of a "alive" sound path there is a microphone more often. Now on the majority scenic ploschadok the dynamic and condenser microphones intended both for a vocal are applied, and for podzvuchivaniia musical instruments - shock, acoustic guitars, grand pianos, etc. Depending on purpose microphones have the various diagram of an orientation. The greatest distribution have received omnidirectional, kardioidnye, superkardioidnye and microphones with the diagram of an orientation of type "eight".
The basic criteria of a choice of a scenic microphone are wide enough range of working frequencies (from 40 up to 16000 Hz and above), high sensitivity and low propensity to "zavodke" (occurrence of the dissonant phenomena in a sound path), a low level of own noise resulting imperfection of the electric scheme of a microphone, type of power supplies (for condenser microphones), optimum weight, appearance of a product and, certainly, the price. One of the most known and popular firms making microphones, is Shure. With microphones of this firm it is possible to be quiet for scenic quality of a sound, thus their cost is rather low. Strict requirements of professionals are answered with characteristics and design of microphones AKG, products of companies Beyerdynamic also are popular, Sennheiser, etc. the Range of the prices is wide enough, however on the average the sound microphone costs from 100 up to 250 dollars.
Communication of a microphone with other devices of a sound path (however, as well as other communications) is carried out by means of the special cables providing qualitative transfer of a signal and reliable contact. Fine means of the communications are made by companies Neutric and Cordial. Cables of firm Symetrix are widely applied also. Recently many vocalists and instrumentalists aspire to use in the work the radiomicrophones providing unlimited freedom of moving on a stage, an opportunity of an output in a hall, etc. Switching in this case is carried out by means of odno-and two-antenna radiosystems. The complete set of radiosystem includes the radiomicrophone consisting of a dynamic or condenser microphonic head and the transmitter which signal is fixed by the reception device.
Qualitative radiosystems are characterized by enough greater radius of action (the order of 90 meters), their radiomicrophones are tolerant to the noise transferred from the case, thus the case differs high durability. The above the range of working frequencies of radiosystem and is more quantity of channels on which communication can be carried out, the above its price. Among manufacturers of radiosystems it is necessary to note such companies as Samson, Shure, Beyerdynamic, cost can change from 300 up to 5000 dollars.
Signals from separate microphones, sound pickups and electronic musical instruments often demand additional processing with the purpose of improvement of their quality. The diversified devices can be included in a path of processing of a signal. For example, to relieve a signal of various noise, whining, cracklings and other defects, the parametrical equalizer is used. With the purpose of transfer of all riches of the sound perceived by a good microphone, the external microphonic preamplifier is used. Clearness, detailed elaboration of sounding and strengthening of effect of presence provides eksaiter, and the control and neutralization of peak loadings are guaranteed with the compressor.
One of world leaders in manufacture of devices of processing of a sound is Lexicon. At some Moscow restaurants and clubs works and does not cause censures standard complex RSM 80 these firms. Also it is impossible to bypass attention equipment Aphex, Drawmer, Furman. Depending on a complete set cost of the equipment of a path of processing of a sound can change from several hundreds up to tens thousand dollars.
Heart of a sound path is miksherskii the board. The destiny of each concrete sound here is solved, there is a mixing in the necessary proportions of signals from all participants of scenic action - a word, music is born. At will of the operator working during a concert for miksherskim the board, acting signals can be subjected to additional or primary processing (if external preliminary processing of a signal for any reasons was not carried out) by means of a mixer.
At a choice of a mixer it is necessary to remember that the number of its inputs should correspond or a little exceed number of possible sources of a sound signal. The main advantages of any board are the low noise level, stability to overloads, compactness and the reasonable price. Good miksherskie boards for a "alive" sound are let out by firm Crest. Mixers Soundcraft, Allen&Heath, Soundtracs are often used also. The price on excellent concert miksherskii the board for restaurant kolebletsia on a mark 5 - 10 thousand dollars.
The target signal miksherskogo the board represents a ready piece of music which it is possible to listen through headphones. But that music became property more the broad audience of listeners, the signal is necessary for strengthening. For this purpose so-called amplifiers of capacity are used. The requirements shown to amplifiers, are various enough, however one of the main things is high reliability of the device which is provided, in particular, with powerful system of compulsory cooling of the electric scheme, system of the protection guaranteeing duly switching-off and smooth inclusion of the device in case of occurrence of a supernumerary situation, and other means. For improvement of quality of sound amplification together with amplifiers of capacity various additional devices - limiters, crossovers, atteniuatory, etc. can be used
In Russia amplifiers of capacity Crest use the greatest popularity. The Wide circulation other devices among which it is necessary to note Carver, JBL, QSC, ABT, Yamaha, Ashly, Sound Tech, Telex, etc. the Price polutorakilovattnyh have also amplifiers of capacity of these manufacturers - within the limits of 800 - 2500 dollars.
Acoustic systems borrow one of the most responsible places - they finish a sound path. On quality of their work in many respects depends, whether the visitor of restaurant can hear rather alive sounding in correct dynamic and frequency ranges, distinguish its slightest shades. Qualitative low-frequency systems (subwoofers) should provide clearness at strengthening a sound on low and ultralow frequencies, reproduce high sound pressure, giving to a sound depth. Broadband systems in an ideal should differ a high level of sound pressure and absence of distortions at work, providing a pure and distinct sound in a range of frequencies from 40 up to 22000 Hz and above.
Among the companies which are letting out acoustic systems, the special place borrows Tannoy. Production of this firm has excellent operational characteristics and high quality design. Very good acoustic systems make firms Martin Audio, EAW, and also Trace Elliot. The prices for acoustic systems kolebliutsia in enough wide limits - here all depends on your financial opportunities.
