This article pertains to Dual Mono with all {{L1}} systems.

=== {{L1}} Systems ===

The {{L1}} systems have extremely wide horizontal dispersion. As a result, running multiple {{L1}} systems in the same sound field may result in overlap. The comments below are applicable in that context.

===Non-{{L1}} Systems ===

The {{F1}} and {{S1}} systems have narrower horizontal dispersion. If you space those systems apart or aim them to avoid overlap, this article is not applicable.

;Dual Mono

==Dual Mono==

This is amplifying the same sound source through two separate loudspeakers.

:For a single performer/single source it's not quite so clear cut. One will be more accurate (i.e. sound is clearly located at performer's position, more consistent spectrum) and two will sound wider and more spacious. In the end, that is an artistic decision, depending on which one is closer to your artistic intent.

=== Gain Before Feedback ===

To optimize gain before feedback, each microphone should be heard through only one {{L1}}.

Feedback occurs when the sound from the loudspeaker (or loudspeakers if a microphone is connected to more than one) is louder at the microphone than the sound of the voice. As you increase the number of loudspeakers a microphone is connected to (e.g., dual mono), you increase the possible paths for feedback and lower the gain before feedback.
