Guide To Church Sound System Design

By Claudine Hodges


The term soundengineer is a generic term that can applied to different businesses, with specific qualifications. The soundengineer has the function of managing sounds in different industries. A soundengineer registered or mixes sounds or music programs, through real or virtual machines: amps, preamps, compressors, EQs, effects, effects pedals (church sound system design).

On set, working with it (or them) boom operator (boom operator), it ensures the proper sounds recording dialogues or lyrics, trying to avoid as much as possible all the noise and controlling levels 'check in; it handles playback, provides, moreover, the mounting of only ambient sounds necessary (that is to say, outside of time saved location). This profession has evolved over the technical advances of cinema. At the beginning of talkies, there was the reign of omnipotence of soundengineer on set with his Fisher pole, then the movie came out of tray to go and shoot in natural settings. The chief sounds operator also uses multitrack hard disk recorders (genus Cantar) or memory cards.

Technologically similar to microphones used in studio, the microphones for sounds systems meet the different signals to recipient. The consoles have a concert dedicated to large number of entries provided for microphones, advanced EQ sections, a large number of auxiliary buses, especially for consoles dedicated to returns. DJ oriented consoles have little input - and most stereo, simple adjustments, a smaller footprint, and for a long correction "RIAA" for turntables. In Public Address, the console is reduced to a minimum and sometimes integrated directly into amplifier.

Sometimes placed on each console output an equalizer that can correct the overall response ofn enclosure according to its intrinsic defects, acoustics of venue, frequencies causing Feedback, operators wishes, etc. These equalizers are mostly graphics but nothing prohibits the use of parametric. The filter separates the signal into different frequency bands distributable by specialist speakers. Filtering can active or passive:

The former is common in Hi-Fi world. The second solution is preferred sounds as it allows greater flexibility (it is easier to correct the settings of an active filter, higher numerical reason that components a passive filter). But above all, the powers involved are the cost, weight and size of components of passive filter capable of supporting hundreds or thousands of watts would cause problems.

It is possible to adopt a hybrid approach, for example with a passive crossover between the midrange and treble a speaker, and active filtering between this speaker and subwoofer. The limiter is a compressor reacts quickly and with a very high compression ratio. Its purpose is to protect the speakers of two risks of destruction: a too large amplitude signal causing a tear of membrane; a high amplitude signal over a prolonged period causing a burning coil.

He deals with the artistic part but knows how to disappear behind the composer. He works with the engineer to interface between artistic and technical aspects: what microphones to use, how to place them, what type of amplifier used, what equalization, what compression, etc.

Before sounds recording session, its preparation are done under the engineer's instructions: arrangement of orchestra, choice of microphones, headphones network installation for musicians. At sounds recording, the soundengineer checks that sounds recordings do not saturate by adjusting the setting best mic preamps and assumes good musical scale. A sounds recording may be said live when all the musicians recorded simultaneously or in successive layers (overdub (first rhythm tracks recorded with a (reference click the Tempo) and other sections: strings, brass, choirs, and solo instruments (in) dubbing instruments and finally solo singer. These records can done bit by bit ((en) punching-in and punch-out)
