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).

The multiplicity of experiences (internships, assistantships event ...) is preferred and can complete an initial training. Studies on treatment / signal theory / Acoustic / music. The sounds systems consists of distribution of sounds signal in a large space with electroacoustic means. A microphone converts sounds into an electrical signal sources. It can replaced by a cell directly sensing the mechanical vibrations of certain instruments (guitar, cello, bass, etc.). Even if the source delivers an electrical signal, it may be necessary to use adapters between the signal delivered and the console needs. A DIbox allows symmetrical and adapt the electroacoustic impedance guitar signal.

The mixer function appears in 1970s and became a specialty. The mixer makes the mixing of source elements from various sources, provided by: Sounds editor "direct" (when there is one), which fixes, cleans and improves sounds dialogues after the image editing; Post become indispensable since the emergence of multichannel recording dialogues shooting.

He often fills the director function because, beyond editing, mixing, clean sounds, it is often a real work of art director requested. These are the same functions as in radio, with the added bonus of professional relationships with people in image. This involves micro investment in harmony with the captured image, and a sharper focus with the image planes reports.

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.

Some big soundengineers can become producers (in), that is to say, interested in production. The soundengineer music is professional contact with artists fully committed to their art. It should at least know apprehend artistic situations sometimes delicate and crucial. Traditionally, the producer advises musicians on song structure, the way it should play them, the expected effect once a recorded song.

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.

The amplifiers increase the signal voltage and are capable of delivering at very low impedances. Technologically similar to what is found in Hi-Fi, they differ essentially in: the involved powers, of order of several hundreds to several thousands of watts; robustness; the extensiveness ofir internal protections (short circuit, overheating, DC, etc.) and their connection: screw terminals similar to Hi-Fi amplifiers leave gradually place Speakon.
