Multiplicity for PAs is Helpful

In everyday life you can find yourself in a situation whereby you are surrounded by multiple people, be it in a restaurant, in an auditorium, or a classroom. More often than not you are with people with whom you are trying to have a conversation with, but being able to hear each other can be challenging. While that scenario is something that may occur from time to time, it doesn’t necessarily mean it has to happen at all, especially at an event where you are trying to project your voice.

Noisy environments may sometimes feel like you’re competing to be heard loud and clear but depending upon what type of portable speaker you are using to project your voice, you can instead create a competitive advantage. The Califone portable UHF line of speakers offers a solution. The PresentationPro™ and PowerPro™ portable speakers each have 16 different 900 mHz UHF frequency channels to choose from that present the type of flexibility a teacher or student making a speech needs. If multiple students are making a presentation, using more than one microphone with a speaker that has only one frequency channel will cause interference that can distort the audio being emitted. Having the option of selecting one channel for one student, a second channel for a teacher and matching a handheld wireless microphone or beltpack transmitter with a hands-free microphone to the speaker’s channels will allow both the student and teacher to project their voices without any cross-talk.

Even a classroom that uses array speakers equipped with UHF frequency channels can be used in conjunction with a PresentationPro or PowerPro speaker to daisy chain them for enhanced audio projection and sound. Creating an atmosphere that lets multiple presenters in the same room project their voices without any friction or muffled sounds coming out of the speakers makes way for a seamless presentation without any audio interruption.
