Think of the stage as a speaker sitting in front of the audience….. sometimes the club or venue actually looks like a box where the performers are positioned. You have the low-end Bass Guitar, Kick Drum and Floor Tom and maybe keyboard sounds or textures. You have the Guitar and Vocals in a mid-rangy area and at the upper end you have symbols and higher range Guitar and Keyboard sounds. All inside the same box just a blasting away at different levels and pointed in all directions.

Now you have a better understanding of the challenge of making these various chunks into a tasty audio stew!

For the best way to present music to the savvy listeners of today, we do what has been done for decades. In the stereo image, you want to create a “room” or “place” for the listener. We have become comfortable with the very low end sounds coming from both speakers at about the same volume. This places the sound to the center of the listener’s field.

We like the vocals or in most cases the melody line to be in both sides equally, again placing the singer in the middle of the left-right field. We are fine if other instruments or singers are more to the left or right as long as the main sounds are where we expect them. We usually place big speakers on either side of the stage facing the audience…… usually in front of the stage and performers…. But as mentioned above this is not a finely tuned speaker cabinet by any means. The components are not necessarily proportionally balanced in volume or location. Setting up the Stage and PA system with this in mind can help reinforce the natural stereo image out in the audience.

Now that I have made a connection that is awkward if not confusing, even though the PA system in all likely hood is a Mono mix coming from both sides or columns of speakers, the listener still hears this as a stereo field. They want the low-end sounds or tones from the center of the stage. Typically the drum – the Kick Drum to be specific for this example – is the most used and most amplified instrument in band situations or where you have audio media. The Bass Guitar player is usually next to the drummer. This helps them keep tighter timing and solid beat, but also supports the stereo image of the listener.

Guitar and other amplified instruments on stage can be heard more from their side of the stage than from the other as an easy example, even if the volume through each side of the Main is sent the same level signal. If keyboards are on the opposite side of the stage from the guitar and also uses a monitor or amp, standing closer to them in front row can make it seem like the keyboards are too loud and those on the other side of the stage think the guitars are somewhat overbearing. It won’t stop them from standing there though! As you get further away from the front of the stage or if the venue is very large, this stereo effect has less and less meaning to the listener. Still, as a rule, most sound systems do not place low-end PA cabinets (or dumps) on one side of the stage and the mid or hi-end cabinets on the other side. It can be however, advantageous to place the low-end dumps in the center of the stage or along the front-center stage area. To make this more inclusive, it is also more comfortable to hear low-end tones coming from an elevation point lower (on the floor, for example) and the higher tones or frequencies coming from higher points (mounted above the stage or on tall poles).

If the volume on stage becomes to strong a level it will negatively affect all the above and more. To reinforce another post of mine, musicians just need to worry about performing great – we sound geeks will make them sound good and loud! I keep dreaming.
