QSC MX3000 power amplifier
The MX 3000a is a high power, low profile professional power amplifier with advanced features and a flexible input. It delivers tremendous power in only three rack spaces, providing high level performance under the most demanding conditions.
A stepped linear output circuit combines high power with high efficiency to provide greater average and dynamic audio performance, while
reducing normal system cooling and AC requirements by greater than 50%. An automatic variable speed fan matches cooling capacity with heat requirements.
The rear panel uses Level 1 of QSC’s exclusive Open Input Architecture™ which allows the use of optional input connectors, input transformers, cinema crossovers, power limiters, precision attenuators, and other signal processing cards as they become available.
