QSC's award-winning MX/MXa Series amplifiers

combine ultra-clean audio performance and unsur-

passed reliability while delivering maximum power

under the most demanding conditions. The MXa’s

achieve superior performance with high-efficiency

stepped linear output circuits,ensuring solid two-ohm

operation, night after night. They’re at home on tour

or in an installation rack; in a main or monitor system;

driving horns or pumping subwoofers.MX amplifiers

are trusted by leading touring companies and

venues around the world.

Stepped-linear output technology on MXa models reduce normal system cooling

requirements and AC current draw by greater than 40%. The MX 2000a's and

3000a's dual monaural construction boosts reliability by providing separate

power supplies for each channel. MXa rear panels feature our exclusive Level 1

Open Input Architecture, which allows the addition of input transformers,

crossovers, power limiters, precision attenuators, and other signal processing

accessories. An extensive set of protection features assure stable operation

and reliability, even under the harshest conditions.
