      Audio Test Equipment

      At Markertek, we carry a wide variety of audio test equipment for analyzing waveforms, measuring sound levels, and much more. We're proud to stock quality audio testers from NTi Audio, Greenlee, and more than a dozen other brands. Whether you need a measurement microphone to calibrate your monitors, or an all-in-one analyzer to measure noise in an event space, we have robust tools for your specific audio needs.

      With an audio analyzer like the NTi XL2, you can quickly obtain a reading of the SPL, Lmin, Lmax, Lpeak, Leq, and many other attributes. Meanwhile, the built-in spectrum analyzer allows you to see the full frequency spectrum as 1/1 octave or 1/3 octave, with the option to capture frequency data in 100ms intervals for future analysis. This handheld device is ideal for live sound monitoring, broadcasting, and building acoustics.

      We also carry a range of handheld impedance meters, including the Gold Line ZM-1P, which can calculate loudspeaker impedance in a myriad of configurations. Once you've installed a loudspeaker system, you can use the impedance meter to measure the total wattage, or you can measure individual components during installation. We highly recommend investing in an impedance meter to protect your valuable audio equipment from electrical damage.

      To learn more about our audio tester selection, call us toll-free at 800-522-2025 or click the "Live Chat" button to chat with us online. We offer a 100% Money Back Satisfaction Guarantee and free shipping on any order, even if you're buying a single accessory. Thank you for visiting Markertek!
