Wireless Intercom Systems Offer Simplicity and Portability

Technology is advancing at light speed, and today there is a broad range of wireless intercom systems that differ in complexity and portability when it comes to indoor and outdoor use. They are convenient to transport and set up, are often hands-free, and offer untethered communication that is comparable to the quality of a wired system and range in affordability and style.

Often used by classroom teachers, corporate presenters and to amplify sounds on stage, wireless intercom systems range from basic portable systems to high-performance systems. Either way, every presentation deserves to be clearly heard, whether your audience is way in the back or right up front.

Basic Components
Public Address (PA) systems will often come packaged with suitable mechanisms to suit particular types of venues and ensure the proper matching of the equipment. The most common include an amplifier, a loudspeaker and a microphone.

Difference Between Analog and Digital
There are some pretty big advantages in using digital technology rather than analog. But it helps to understand the difference. When a wave is recorded and used in its original form, that is known as analog, and when the signal from the microphone is transferred to a tape, that tape can be read, amplified and sent to a speaker to produce the sound.

With digital technology, the analog wave is turned into a series of numbers that are then stored in the device. To hear the sound, those numbers are turned into a voltage wave that provides an approximation of the original wave. When choosing between the two, digital is best because the recording doesn’t degrade over time, the wave always remains the same, and the numbers themselves can be compressed to provide for space savings.

Advantages to Wireless
It is expensive to retrofit a building with a wired intercom system, so by purchasing a device that enables communication without the need to run wires between intercoms will reduce costs and provide the user with more flexibility. The integrated, self-contained design allows the user to set up and tear down quickly, and because there are no cables to disconnect it provides for excellent portability. Another advantage is the fact that wireless intercom systems often come with powerful batteries instead of an AC hookup, so it reduces the reliance on outside power supplies.
