Designed to provide uncompromising fidelity in any environment, the MXA2 bundle combines Fender's legacy of great-sounding products that inspire the greatest players with PreSonus' dedication to crafting top-notch audio solutions. This exclusive bundle is the perfect starting point to jump into the world of in-ear monitoring. These dynamic drivers have a clear, sweet sound due to their full-range frequency response. Constructed with rare-earth magnets, which are more powerful than traditional magnet materials, these custom drivers are sure to please fans of rich, punchy low end. Reproducing bass frequencies properly requires more air movement than needed for other frequencies. The Groove-tuned bass port on this model allows for more air to reach the driver, enhancing the bass response without adding size or weight to the monitors. The 3D-printed housing provides a custom-molded-like fit derived from scanning thousands of ear canals and then compiling the results to create an "ideal" fit that works for 95% of users. This low-profile housing uses 3D printing for a precise fit that seals the ear canal to enhance bass while reducing ambient interference. With the combination of the low-profile slimline shell and patent-pending secure-fit tips, these in-ear monitors reduce ambient noise by up to 18dB, allowing you to filter out unnecessary noise. The HP2 headphone amplifier provides a simple way to drive musician's IEMs. It sports two XLR line level inputs and one stereo 1/8" (3.5mm) headphone output with volume control. Operation can be switched between stereo and mono, and a pan knob lets you dial in your mix. Designed for musicians, the lightweight, compact HP2 can be clipped to a belt or mounted on a mic stand, and operates for up to seven hours on a single 9V battery.
