Audio

CSI has over 30 years experience in the music industry and the audio field. We take great pride in providing you and your organization with the best sound possible. We use best practices and cutting edge technology to handle any scenario and provide you with the best solutions. 

We run into many situations where people have been misled or were under the impression that new speakers or a new console can solve their audio problems. The truth is that there are more determining factors, that only by years of experience, we are able to identify and resolve.  

Are you getting the best out of your system?

 

 

"Churches can be amongst the most challenging environments in which to properly set up a professional sound system. Given that the architectural variance between houses of worship is so great, there is rarely a one-size-fits-all solution when it comes to deciding which equipment you will need and how it should be placed. To top it all off, some churches may require a versatile sound system that allows them to accommodate a variety of different speakers, performers and musical styles - anything from choirs, to soloists to full bands. It can be a real headache if you don't know some of the ground rules to help you through the process. 

One of the major issues to be found when it comes to church audio systems are unwanted echoes, reverberations and amplifications of certain frequencies caused by the large, open design of the main worship area itself. Many churches boast high ceilings with angular walls, and most of the time, these rooms are rectangular in shape. Rectangular or square, 'boxy' rooms have a troublesome habit of creating what are called 'standing waves' of sound. The waves are caused by low-frequency sound bouncing from wall to wall around a room. Standing waves can radically change the way that sound is perceived, depending on the position of the listener. Church attendees in the front row may have trouble hearing certain parts of a sermon or musical piece but others scattered throughout the room may actually be assaulted by amplified low-end frequencies which drown out the whole of the sound itself. 

There are a few possible solutions to this problem. The first is to install what are called bass traps. Bass traps are boxes made of wood and filled with fiberglass that act to absorb low frequency sound before it can be reflected. They accomplish this by vibrating when hit with a sound wave - unlike stiff walls, which reflect instead of vibrate. Properly placed bass traps around a church hall can be an excellent method for ensuring that the both music and speech are able to be heard with clarity by all attendees. 

Alternatively, room equalization (EQ) can be employed instead of bass traps. EQ is the art of managing the balance of frequencies leaving a sound system so that they match the acoustic properties of the space where the system is placed. Equalization can be performed manually, or it can be done automatically by the device itself. When it comes to manually equalizing a church hall for a specific type of sound, sound engineers can actually enter in the size parameters of the space in front of them, as well as the approximate number of people who will be occupying that space. Even the materials that the church has been constructed out of can be taken into consideration. Once this has been entered, algorithms within the device itself can automatically adjust the sound coming out of the loudspeakers so that it is clear and bright, no matter where people are listening from. More advanced equalizers actually use microphones placed throughout a church and 'listen' to the sound that is being recorded. They then use a spectrum analysis which examines the frequency distribution in the room and automatically adjust the EQ to compensate for any trouble spots."
