Providing high efficiency amplification, the MA (Modular Amplifier) series of products introduces operational and performance refinements in a highly adaptable design. Each MA modular amplifier employs a common “digital mainframe” to which power modules of 200, 450, or 1000 watts can be mounted. Flexible by design, each mainframe is populated with either two or four channels of amplification based on the system’s needs and specific loudspeaker or subwoofer application. By allowing the mix of modules, the MA modular amplifer provides efficient use of power, supplying the appropriate wattage level needed for each specific application (i.e. 1000 watt modules may be used to drive subwoofers, while 450 watt modules may be mixed with 200 watt units to bi-amplify the low-frequency and higher efficiency high-frequency drivers respectively).
When combined with PRO’s ALC-3316, PLP-8250, or PLP-8800 loudspeaker controller or processors, installers can use the MA modular amplifiers to quickly and easily power, apply high resolution DSP filters, and calibrate any PRO sound system. When driven by the MA, the output of each loudspeaker precisely mimics the input signal of its assigned channel, rendering performance tolerances previously only attainable at the pre-amp and power-amp level. The resulting resolution of detail and musical accuracy set a new standard for lifelike portrayal of music and video soundtracks alike.
For greater flexibility, looping outputs allow multiple MA chassis to be connected and share input signals. This is especially useful for instalSPECS See next page for MA specs lations employing multiple side channel loudspeakers, or where sophisticated multi-subwoofer configurations are used to address room modes.
Built on proven Class-D technology from ICEPower, each MA modular amplifier operates efficiently, providing generous power while producing little heat. A balanced design, all connections are made via transformer isolated (optional) XLR inputs, minimizing ground-loop hum and buzz problems. In addition, each amp employs world class A-D and D-A converters with native dynamic range of 123Db.
