The amplifiers were placed in the sound booth under the mixer, feeding the monitors and the main speakers from the balcony. The system design consisted of a center cluster with additional speakers for side fills all located behind the suspended ceiling.

The cluster: 6 boxes of McCauley M120 speakers, and 2 subs cabinets (mounted one on each side of the array)  not sure what the side fills are.

The sound was very thin and I could tell that the mids where none existent.

We programed a custom setting in the driverack and the speakers came alive with great sound.

This is what we encountered under the board.

First off, there are some basic rules when it comes to wiring a sound system.

1. Keep audio and power as far apart as possible

2. If possible never run then parallel with each other

3. If you have to cross an audio wire over a power wire, cross at 90 degrees

When you wire racks of equipment try to follow these practices.

Try to run the wires down the rack as follows :

This way will maximize hum rejection from your power system.

Here is a picture of the wiring now. We still have some more work to do to really make it look good but the hum is under control now and they are getting clean recordings now.
