There are several different forms of "trouble". At least initially, let's break them down into Acoustics, Gear, Venue. | There are several different forms of "trouble". At least initially, let's break them down into Acoustics, Gear, Venue. | ||

=== Bass Regeneration === | ==== Bass Regeneration ==== | ||
[[Bass Regeneration]] is a special class of feedback, or regeneration, that exists in all live amplification systems. It is a very insidious and hard-to-confront phenomenon, but it is responsible for a lot of bad sound. Resonances of all kind, including those of musical instruments and those of large “boomy” rooms will also contribute to bass regeneration. ...

=== Hiss === | ==== Hiss ==== | ||
If you have all settings on the {{PS1}} set straight-up (including the {{R1}}, with nothing connected, it is not unusual to have an audible hiss. The reason: The System is pretty much running wide-open at full power with no input. If you had a microphone or a recorded source playing - the System would be extremely loud. If you were performing at these settings the hiss would be inaudible. | If you have all settings on the {{PS1}} set straight-up (including the {{R1}}, with nothing connected, it is not unusual to have an audible hiss.

You want to isolate the source of the hum, but this can be tricky because hum is usually the result of two or more devices interacting. | You want to isolate the source of the hum, but this can be tricky because hum is usually the result of two or more devices interacting. | ||

If placed in a corner, ask if you can be placed in the center or a wall. If you the "short" wall in a rectangular room is wide enough, then that is probably your best choice for the wall behind you (if the long wall is not greater than 100 feet). | If placed in a corner, ask if you can be placed in the center or a wall.
