Martin Audio MA4.8Q AmplifierMade By Lab.Gruppen
Housed in a convenient 2U package, the MA4.8Q 4-channel amplifier allows for the adjustment of maximum voltage peak, gain adjustment and has on-board network capability for monitoring and control. With these features it is now possible to specify identical amplifiers in an installation and then adjust each output to the very specific requirements of the speaker system. A typical large-scale system is a combination of high-powered speakers, full range in-fill speakers, 70/100V ceiling speakers, with an active speaker management system. With switchable outputs and on-board network capabilities, the MA4.8Q can be designed into a complete value engineered system handling all amplification tasks.
