JBL MPA600 2-Channel Amplifier 440-Watts RMS

The MPA Professional Audio Amplifier Series is specifically matched to the characteristics of JBL speakers. They deliver a wide range of output power to accommodate even JBL's most powerful transducers. They exhibit good peak power capability and excellent dynamic headroom to accurately reproduce musical transients. Each amplifier includes a protective output limiter to protect both the amplifier and the loudspeaker form excessive power. The limiting action curve is perfectly matched to JBL transducers taking full advantage of their low power compression characteristics. The action of the limiter does not "rob" the system of acoustic power since the total output of a heavily distorted amplifier is the same as the "limited" MPA amplifier, but with extremely clean, non-distorted sound. Open Input Architecture™: JBL systems philosophy also extends to the input stage of the amplifier. Flexible input cards allow these amplifiers to be tailored to a variety of applications, and configurations can be changed easily as new situations arise.
