One Size Fit All PA System

Choosing the right Public Addressing (PA) system for a business premise can be a daunting task and a hassle?

To ease the process of decision-making and to take away the complexity of understanding a PA system, AEX system innovated the Medusa 3 Series Integrated PA System.

Usually, the completion of a PA system setup would require at least a Pre-amplifier, Audio input selectors, an Emergency microphone, Automatic evacuation message unit, Power amplifiers, Amplifier changeover unit, Amplifier monitoring unit, Speaker zone selectors, and Remote paging microphones. That’s a lot of things to build the PA system up.

But, the dull side of purchasing the normal PA system is having to study numbers of equipment and decide which would be suitable for the premises.

The disadvantages of setting up a PA system with number of equipment are:

  1. Occupies more space: Requires costlier racks and takes up business space that could otherwise be used to serve other business functions.2.
  2. Complicated to set up: The setup will be a lot more complicated and only professionals can do it. Money spent on professionals to rack up and get the system running is expensive.
  3. More cables and accessories: Equate to more money spent as well.
