      Power Amplifiers

      At Markertek, we carry power amplifiers for a variety of applications, including live sound, broadcasting, and more. These cutting-edge amplifiers provide an efficient power source to your speaker system, so that you can achieve the best possible performance, while also reducing energy costs. We're proud to carry powered amplifier systems from respected brands like Crown, QSC, and Stewart Audio.

      What is an Audio Power Amplifier?

      A powered amplifier (also known as a "power amp") recreates an audio signal at a stronger level, so your loudspeakers can play it back at full volume. Typically, this is the last piece of equipment in the signal chain before the audio reaches the speakers. Before the audio power amplifier, you might also have a pre-amp for boosting low-power signals, an EQ for adjusting frequencies, and other tonal/effect controls.

      If you're searching for a professional-grade power amp for installed sound applications, look no further than the Crown CDI-1000. This two-channel marvel produces crystal-clear sound with virtually no distortion, as well as advanced protection against power shortages and overheating. Meanwhile, if you're looking for a four-channel power amp, the QSC CXD.4 contains robust DSP functionality, including multiple EQs, alignment delay, and limiting.

      To learn more about our speaker amplifier selection, click the "Live Chat" button to chat with us online, or call us toll-free at 800-522-2025. We offer a 100% Money Back Satisfaction Guarantee and free shipping on any order, even if you're purchasing a single speaker accessory. We also carry a wide variety of studio monitors and subwoofers for your rig. Thank you for visiting Markertek!
