:Dual mono (with the {{L1}} systems) is usually not a good idea, if you have more than one performer. With more than one performer/source it's in my opinion always preferable to separate the sources (i.e. one source per L1). The spatial separation and precise localization help more with clarity much more than the added gain.

: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 the 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.
