We have a fairly standard audio system in our church.
We have a Soundcraft MFXi mixer at the sound desk at the back of the church. Note: the main left output goes to the speakers while the main right output goes to Zoom for our simulcast services. There is a power switch underneath the sound desk on top of the drawers that powers the mixer and wireless receivers.
Our amplifiers are mounted in a rack in the Wardens Office. A Furman power conditioner provides power to the whole rack.
Mono audio coming from the mixer goes to the dbx 2231 Equalizer and from there goes to both the Carver amplifier and the QSC amplifier. Note: the top half of the equalizer effects the Carver and the bottom half the QSC.
The QSC MX3000a amplifier is set up in parallel mode (the same signal goes to both channels) and is connected to the main speakers. Note: the input is non-standard: Pins 2 and 3 (Tip and Ring) are switched so we switched them back at the TRS plug.
The Carver pm1400 amplifier (schematics) is connected to the two sets of speakers further back in the sanctuary. Ideally the audio to these speakers should be delayed to increase legibility at the back of the church. Note: at present this amplifier is turned off as the speakers are very quiet. This needs to investigated.
We have three pairs of speakers. The main, front of house, speakers are EV ZX3.
The second and third pair are auxiliary speakers, EV S-40, and are placed on pillars 26′ and 37′ away from the main speakers. Note: at present they are not connected.
There is an EV ZXA1-Sub subwoofer to the left front of the church.
We have four EV ZxA1 powered monitors at the front for the musicians.
We have Sennheiser EM 100 G3 wireless microphone system with a lavalier microphone for Julie. The microphone and the body pack transmitter are in the top drawer at the mixing desk.
We have two EV RE-2 wireless microphone systems with both a handheld mike and two lavalier microphones. They are in the middle drawer.
We have a 16 input/4 return snake from the right front of the church to the mixer.
What to Do Sunday Morning
- First turn on the power switch under the sound desk to power up mixer (important that this is first)
- turn on the musicians’ monitors and subwoofer.
- go the Wardens Office and turn on the Furman power conditioner to power up the amplifiers.
- Give Julie her wireless microphone.
When it’s time to power-down the system make sure to do that in reverse order as above (this is the important part: turn off the mixer last). Remove the batteries from the wireless mikes.
