Benefits of Modular Amplifier Systems: A modular input system allows users to select input modules which match the needs of the application. In a fixed input system, all the inputs are provided in a "fixed" format, without possibility of customization. Modular mixer/amp systems are preferable because it allows for configurations that are flexible and changeable. This is especially important if an installation requires an unusual assortment of inputs, or may be subject to reconfiguration from time to time. Potential applications include school multi-purpose systems, church sound, hotels, motels, conference centers, retail establishments, warehouses and car dealerships.
