The diagram below shows a typical small House of Worship audio system. This system utilizes four
microphones, one for the Pulpit and three on the choir. A Master volume control (Atlas AAVC-10K) is
connected to the "VCA" terminals for overall level control. For background music, a CD player's audio
outputs are connected to Input 6, and a recording device (cassette recorder or computer's audio input) is
connected to the Tape Out jacks. For system tuning, a 1/3rd octave graphic EQ is connected to the Pre
Out/Pwr In jacks. For the "cry room" an 8

speaker is connected to the Zone 2 "1W 8
