What are omni-directional and uni-directional speakers?
Omni-directional speakers usually send sound in all directions, front and back. They are not standard, and are usually found in outdoor plazas. Uni-directional speakers only send sound in one direction – forward. This is normal for most PA speakers. There are also omni-directional microphones, which are not good for live music. It is better to use microphones with a “cardiod” pattern. The “Sum” is sometimes called “Mono”, as it is the combination (or addition) of the Left and Right signal. Check out the sound engineering Q&A for more on this topic. This answer can be edited and improved by you on the Guitar Noise Wiki. Go to speaker types and select edit to make improvements.
