Setting up a sound system is a great challenge for anyone. Pastor Davis first approached me about setting up the sound system at the new church in Graham, before its scheduled  opening 1 Jan 1999. “I was astonied until the evening oblation” as Daniel the prophet said. Thankfully, a very patient sound engineer in Missouri (…more)

 

There’s a lot that can go wrong with a  PA System. Here’s a few tips for the ‘big stuff’. Those things that we’re afraid of, that make loud noises and scare us to death. Not all problems are that way, some are just little annoying things; annoying enough to disturb a church service. Here’s a (…more)

 

Crossovers Crossovers separate frequencies and sends their signals to the proper speakers. In other words, bass frequencies are sent to the subwoofers, midrange and high frequencies to the other speakers, etc. Full range speakers produce all frequencies and don’t need crossovers. Few people need subwoofers, delays or crossovers in small buildings and small PA Systems. (…more)

 
Input

Input devices put audio signals into your sound system. One common method of inputting audio signals into a system is using equipment such as microphones, instruments, and various types of audio equipment. Quality microphones are expensive but they give you the best vocal tone quality, and less feedback (squeal)  from the speakers.Get the best Mic you can (…more)

 

Output devices send audio signals out ! An audio device such as a mixer or amplifier, receives audio signals at its inputs and then, when it has done its job, it sends the signal out. The signals go through the mixer’s pre-amps, (since they aren’t very strong signals) then they are processed by the EQ (…more)

 

An amplifier increases the power of a signal, and is the last device in the signal chain before the final destination – the Speakers. There has to be an amplifier somewhere, to make the signal strong enough for the speaker to produce sound. There are 3 ways to go about this, in a PA/ Sound (…more)

 

Input devices put audio signals into the system. Signals go into the mixer input jacks and are then distributed as needed. The mixer blends all the signals together to produce one stereo audio signal that can be routed along many different paths. You can put signals to the system by either microphones or cables. Microphones (…more)
